What is an Auxiliary Fan??


A man who does not know what an auxiliary fan is.

You’re driving your car and you notice that something is wrong… seriously wrong. The mechanic pops the hood up and looks around a mish mash of engineering parts. This is the part where you go, ‘Oooohhhh!’

The mechanic in his dirty gray jumper wipes his hands with a greasy rag tucked in his back pocket. He then turns to you and says, “Your auxiliary fan is not working. The fuse is blown.”

You’re not quite sure what the mechanic is talking about. Instincts lead you to a completely different idea, because the fan blower seemed to work fine when you switched on the air conditioner this morning. Afraid to sound stupid and end up being charged extra as a result of it, you nod your head and pull out a wad of cash hoping not to hear about the problem again.

As you drive home, you wonder, ‘What in the hell is an auxiliary fan?’

Auxiliary Fan


Worry not, my troubled driver, for that is exactly what I am here to explain. While car parts have their own unique purposes, one must realize that they function in a structural order. Each part relates to one another and therefore, there are a lot of supporting systems that makes your car run like a perfectly oiled machine.

The auxiliary fan serves a very important purpose in supporting other parts in your car. We have to know that, like all fans, the auxiliary fan works in various speeds, and each speed has its own function. At low speeds, it cools the condenser of your air conditioning unit when it is overworked or when it has reached a certain temperature. In the same manner of kicking in at certain temperatures, the auxiliary fan notches up to high speeds when the engine needs to be cooled down. This also helps in cooling down the radiator when idling or moving through slow traffic.

The main purpose of the auxiliary fan, as mentioned in the previous paragraph, is to control and cool down the different parts of your car so that it runs efficiently. So, if there comes a time again when your mechanic tells you that the auxiliary fan needs to be replaced, you can just smile as you sign the repair form, knowing full well its purpose in your beautiful car.

How Do I Maintain My Flat Fin Radiator?

Taking care of your Flat Fin Radiator is not a lot of work, but it will definitely make a huge difference and will prevent you from experiencing troublesome surprises on the road. Here are some tips for you to keep your Flat Fin radiator running in peak condition:

  • Regularly Perform a Radiator Flush

For your radiator to do its work effectively, it needs to be free from any dirt or blockage. You can make sure your radiator is clean by doing a radiator flush.

So here’s how you can do a Radiator Flush:

Step 1: Prepare all needed materials (radiator flush solution, coolant, funnel,
cloth, screwdriver/wrench, container for draining), and make sure your engine is cold before anything else.

Step 2: Place your used coolant container beneath your radiator’s drain, and
then open the radiator’s drain plug using a screwdriver or wrench and let the coolant pour out into the receptacle until it is empty. Close the drain plug.

Step 3: Remove the radiator fill cap and pour the radiator flush solution, then fill the remainder with water. Replace the radiator cap.

Step 4: Turn on your engine and warm it up for about 10-20 minutes.

Step 5: Turn off the engine and let it cool.

  • Do a Radiator Coolant Check

Your car’s coolant helps maintain optimal temperature. Thus, it prevents overheating and protects your radiator. It is a mixture of 50% water and 50% glycol, depending on your vehicle. Glycol is an antifreeze that has special properties; it guards the radiator from corrosion and rust.

To check your coolant level, you simply need to look at the white plastic overflow tank beside your radiator. These containers usually have high-low level labels on them which will help you determine if it’s time for you to replenish you coolant. If your coolant level is already low, just remove the cap on your coolant tank and add your mixture until it reaches its recommended level again. And then, place back the cap to close the receptacle.

It is also good to know that there are three types of anti-freeze.

  1. Ethylene Glycol or Polyethylene Glycol – a standard coolant for most radiators
  2. Non-Toxic Radiator Coolant – a coolant that doesn’t have ethylene or polyethylene glycol which are both toxic (if one is exposed to great quantities for long periods of time)
  3. Extended-Life Anti-Freeze Ethylene Glycol Coolants – this is the one lasts longer than the others

Moreover, here are other additives you can use:

  • Nitrates – corrosion inhibitors, buffers
  • Silicates – corrosion inhibitors, especially for aluminum radiators
  • Carboxylates – buffers, corrosion inhibitors
  • Borates – buffers which help reduce corrosion and cavitation, extends the life of a coolant, raises the boiling point of a coolant, and protects from the acidity of an anti-freeze.

Do not mix different types of anti-freeze. This can decrease the effectiveness of your radiator. Always perform a radiator flush before changing types.

Additional Tips

-Always make sure your engine is cold before removing the radiator cap. Touching a hot engine can cause minor or serious burns if you’re not careful.

-Keep the coolant waste away from the reach of children and animals because it is toxic.

-Properly dispose waste coolants according to local hazardous waste regulations.


When Do I Change My Flat Fin Radiator

Unlike a milk carton which has a shelf life stamped on its label, a Flat Fin radiator does not have an expiration date indicated on its body. If that is so, how would you know when you have to change your Flat Fin radiator? This is significant especially if you are the type of person who wants to make sure his car is in perfect condition so as to prevent any mishaps, such as overheating, which can definitely damage other engine parts, cause delays, and decrease productivity. More so, if you are working with heavy machineries and large generators, you would want to avoid encountering such engine problems.

Unfortunately, it is hard to say the exact duration of your radiator because it depends on different factors such as the weather or the type of car you are using. However, most automotive mechanics suggest that a well maintained radiator can last for at least 8 to 10 years, or even throughout the lifetime of your car.

To be able to maximize the life of your radiator, make sure you observe maintenance routines such as keeping an adequate amount of coolant and regularly flushing out your coolant system.

It is also important that you get a high-quality, economical, and durable Flat Fin radiator. As you may know, radiators primarily work to maintain the optimal temperature of your engine by absorbing heat through its fins and diffusing it into the air. This is essential because without proper heat regulation, you can expect frequent overheating, and later on your engine may break down. Quality radiators definitely work better and last longer than ordinary ones.

Additionally, your radiator and the other parts of your car should be periodically checked to see if there are problems. Watch out for signs which may indicate that your Flat Fin radiator already needs to be replaced. Such signs include cracks or leakages. Leaks can be manifested by an unexpected drop in coolant levels. You can also inspect if your thermostat is working fine. Note any unexpected change in your vehicle’s temperature because this is a hint that your thermostat may be broken. Lastly, look for corrosions and rust build up. These are signs of deterioration.

Before you decide to change your radiator, you should assess if it really is damaged. Otherwise, there may be some other components that need to be examined. You may do some troubleshooting by checking other parts of your car such as the intake manifold gasket and the water pump. Take note that a broken water pump may have the same indications as with a worn out radiator. If you are not sure what to do, you can ask a mechanic to take a look at your car.

Your Flat Fin radiator can last a really long time if you take an excellent care of it. With proper maintenance, you may not even have to replace your radiator since it can last throughout the lifetime of your car. Preventive maintenance, which is changing your radiator before it completely fails, is also highly recommendable.

How Car Airbags Keep You Safe

Since the year 1987, white bags designed to be filled with air – aptly named the airbag – have saved over 25,000 lives. That’s a lot of lives, which is why the U.S. government has made it a requirement for airbags to be included in all vehicles. Regular maintenance of your car and its parts such as the radiator, leafsprings and so on certainly contribute  to your safety on the road, but airbag systems provide you protection in case of collisions.  Here is a short video for the sake of show and tell and the awesomeness of stuff in slow motion:

From the video, you may think that the airbag doesn’t seem like much of a safety device. But believe the 25,000 and more people, those things are life-savers. And every driver, no matter how experienced they are, should acknowledge that their car can never be completely safe without an airbag.

An airbag, as good ol’ Wikipedia defines it, “is a vehicle safety device that consists of a flexible envelope designed to inflate rapidly during an automobile collision, to prevent occupants from striking interior objects such as the steering wheel or a window.” Now we could go deeper than that and plunge into the complex science of airbags and car collisions, but in the final analysis, it’s important to know that the combination of a seatbelt and an airbag would largely decrease the chance of an injury during collision. When it comes to your safety, two precautions are definitely better than one.

But of course, I won’t leave you with that. The reason why I didn’t go to the specifics because the video featured below already has. Here are experts who know exactly what they’re doing and talking about when it comes to airbags. And a special shout out of course, to the crash test dummies that are always ready to sacrifice their fake organs for the safety of our real ones. Come on, let us live curious and learn more about airbags together.

Everyday Checklist for Preventive Car Maintenance

Prevention is better than cure. I don’t know about you, but I really believe that statement. Whoever said those magical words is brilliant person who actually thinks practically. The statement doesn’t only talk about a person’s health. Car owners should also think about the fitness of their car. Yes, owners also need to monitor their car’s shape in order to experience great engine efficiency and excellent car performance. But how do you exactly prevent a car’s easy wreck? Keep an everyday preventive maintenance checklist. These are the major aspects of your vehicle that should be given preventive maintenance; check them every day before starting your car.

Battery. Each cell is the chamber of the heart of all electrical systems. Failure of this would prevent your car from starting. Check water level (for non-maintenance free batteries) and dirt or sludge on the connecting poles.

Brakes. This is the most significant mechanical device that controls your car. Check them, both foot brake and hand brake, regularly.

Lights. This is one of the most important parts of your vehicle because this is the only guide you have in the dark, especially when you’re driving at night. Be sure to check all lights – front, rear, brake, signal, hazard – by turning them on before you leave, especially in long trips.

Oil. This is the blood life of your lubricating system. It provides protection to your engine, especially those with metal to metal contact. You don’t want your car to suffer from Arthritis, do you? Lubrication is a vital aspect of your vehicle. Change them regularly together with the oil filter.

Water. Imagine yourself running for a long time. Now what’s the first thing you will look for when you reach a convenient store? Refreshments! Water provides the coolness that the engine requires after a long use. Checking the water level of the radiator will prevent overheating, most especially during the summer season, so better check regularly.

Fuel. As humans can’t go on with their daily activities without food, so as your car – gas allows your car to run. It is a combustible substance that provides energy to your car. Considering the traffic nowadays, you cannot afford to have your fuel at the minimum level. Otherwise you will use it up and run out of gas while in traffic. Visit the nearest gas station when needed. Remember to put the correct fuel for your engine. Otherwise, your car will not perform efficiently.

Fluids. Observe how easily manufactured well-maintained cars are, and how they smoothly come to a stop upon stepping on the break,. This is the magic of steering and brake fluids. Car fluids are supposed to be checked regularly for a trouble-free ride. Also, it wouldn’t hurt to use eco-friendly fluids to protect our environment.

Accessories. Radiators, mufflers, and leafsprings are just some car accessories in need for a possible wear and tear. Every little damage that might happen to any of the car accessories would make a difference in your driving comfort.

Tires. Rotate your tires approximately every 10,000 kms. Moreover, check the air pressure of your tire. Ensure that the front and rear tires have the same pressure.

Tools. Bring the necessary paraphernalia like tire wrench, jack, jack handle, screw driver (flathead and Philip’s) pliers, adjustable wrench sizes 10 and 12, open and close wrench, and an Early Warning Device (EWD). This will be handy, especially if your car breaks down in the middle of your journey. And of course, don’t hesitate to call road assistance.

Cleanliness. It is true that it’s next to godliness. I’m pretty sure you don’t want your car to look so filthy. It is a preventive tool, since in the process of cleaning, defects and damages are often discovered. Cleanliness of the automobile reflects the personality of the owner.

Horn. A type of a warning signal, horns are very valuable to both drivers and pedestrians. In fact, horns are actually used more often than that of other warning signals. But car horns get damaged too. One day, they may stop honking and there’s nothing you can do but to get them replaced. Look for stuck debris and dislodged pieces of plastic around the horn, these things can cause a horn to stop working properly. Checking your car horn will also allow you to check your steering wheel, since the horn is attached directly to the steering wheel. Well, talk about hitting two birds with one stone, eh?

Too many to remember? Let me give you an acronym, BBLOWFFATTCH or simply BLOWFATCH. That way, you will not forget to recall these aspects of your car. Write these things on a piece of paper and pin it somewhere in your garage. If you have time, you can even create a photocopy print outs of the checklist. Maybe you can even add some more on to the list to make you more preventive.

10 Things I Discovered about Flat Fin Radiators

When it comes to cooling down your engine, the radiator is of great importance. This is especially true during these hot summer months. Here are some of the interesting tidbits I’ve discovered about flat fin radiators

1) Flat fin radiator cores have 3 types of materials – Brass, Copper, and Steel fin. These can also come in a non-louvered or louvered fin construction by which these are specifically designed in ensuring a maximum airflow. These types can also be structured with both high-flow and low-flow tubing

2) Having been produced in copper or brass, flat fin radiators are well-resistant to salty and acid conditions.

3) Different types of flat fin radiators come in different sizes – the Copper is usually 2 rows up to 8 tube rows with a core thickness of 37 to 150 mm and its fin pitch is also 2.2 mm, 2.5 mm, and 3 mm. As for the Steel, it is normally 3 rows up to 8 rows with a core thickness of 57 to 150 mm and its fin pitch are also 2.2 mm, 2.5 mm, and 3mm (just the same as the Copper’s).

4) The core of a flat fin radiator looks like the picture below:

5) Flat fin radiators are designed for heavy equipments and large generators. Heavy equipments are large fuel-run and driver-operated machineries that are utilized in performing “heavy” tasks namely, earth moving, heavy lifting, demolition, digging, and light equipment or material transport.

6) The flatness of a fin in a flat fin radiator can also be measured by its thickness, and the unit of measurement used is millimeters.

7) Flat fin radiators offer OEM (Original Equipment Manufacturer)- quality, durability, and high-cooling efficiency to its users.

8) A fin in a radiator works by cooling a fluid and it is made from a thin sheet of heat-conductive metal.

9) Flat fin radiators are very useful especially in our polluted environment because its straight-through fin makes the cooling system insensitive to contamination. Aside from that, it is also easy to clean.

10) Flat fin radiators are available at Roberts Automotive and Industrial Parts Manufacturing Corporation!

Detecting Problems with Your Flat Fin Radiator

If you drive a lot, one of the problems you’re likely to encounter is an overheated engine. Just like how the human body needs sweat to cool down, the automobile engine also needs a cooling mechanism – more so when the engine is operating in a hot environment. This is where radiators come in. The flat fin radiator is a type of radiator where “pins” are spread across the engine to cool it down. Since these radiators fight off heat every day, they are easily subjected to wear and tear. Here are some tips for you to detect if your radiator is already having problems:

Don’t wait for your car to overheat while you’re on the road, be aware of signs that your radiator is not performing its job.

  • If your car overheats a lot recently, then it’s obvious that your radiator is no longer doing its job. It’s most likely already broken and it’s high time for you to replace your broken radiator. As a driver, you should be able to notice that there’s a problem with the cooling system of your engine when the area around your legs feels warmer than usual.
  • You can always check your radiator if you think there’s a problem with it. Unfasten the radiator cap and take a look at the radiator if there’s anything unusual. If you don’t know what to look for, you can always go to a mechanic to check your radiator.
  • Consider the last time you placed coolant or water in your radiator. If the last time you did this was years ago, then your radiator may have already been running dry for a very long time.
  • Check if there is any leakage happening around your radiator. If you feel that you are placing coolants very often, then the problem may already be a leaking radiator.

If you are not familiar with what to do then it’s advisable to consult a mechanic instead. Remember, a problem with one part of a car may not necessarily mean that is the only problem with your car – it may just be a symptom of a bigger problem.

Radiators: How hot is too hot?

We often have that notion that the hotter the engine is, the better its performance will be; that’s why many of us warm-up our engine first before going for the drive. Well, it’s true that for engines to perform at its optimum best, it has to be hot. But there’s also a maximum temperature for that efficiency; anything more than that, heat will start to deteriorate the engine and you’ll end up with an overheated engine.

Can’t take the heat? So can’t your engine. Keep your engine at the right temperature with the help of an Evercool radiator.

How then, will you maintain that ideal engine temperature? You don’t! That’s the job of the radiator. Radiators such as flat fin radiators try to spread as much area as it can to cool as many sections of the engine as possible. Your job is to keep the radiator cool enough for it to control the temperature of the engine. Here are some facts for you to know about engine temperature:

  • The normal temperature of an engine should be around 90 to 105 degree Celsius. With the help of radiators, the engines can go up as high as 135 degree Celsius. The radiators will be there to back up as the cooler all the time. That’s where flat fin radiators become useful as they can cover a lot of area to control the above-average temperature of the engine.
  • Coolants play a big part of how high your engine’s temperature can go without overheating. Pure water is not as effective as those mixed with coolants. Coolants are more expensive than water. A mix between the two would be good to keep cost at a minimum while attaining better cooling efficiency.
  • The primary cause of overheating of radiators is a leaked radiator. The coolant goes out which leaves the radiator nothing to help absorb the heat of the engine.

Know Your Auto Parts: Flat Fin Radiators

When you look at a picture of a flat fin radiator, you might mistake it for the radiator part of a refrigerator. True enough, a flat fin radiator does look like one. And in fact, the flat fan radiator of an automobile serves a similar purpose as  that of a fridge. However, don’t mistake this car part as unnecessary; because once you understand what the flat fin radiator does, you’ll realize how important it can be in ensuring you a smooth ride while prolonging the life span of your engine.

Invest in a good-quality flat fin radiator to ensure efficient engine performance.

The purpose of radiators

Radiators are there to absorb or give off heat depending on the temperature of the engine. It’s important to stabilize heat because over heating could cause major problems with your car. One overlooked importance of radiators is that it provides the ideal environment for the engine so the engine can operate at an optimum efficiency. Considering the size of engines, there are different kinds of radiators that serve different purposes.

What’s the need for a flat fin?

Flat fin radiators are designed to evenly spread the radiator’s effect throughout the radiator area. The more fin count (or number of fins per inch), the more area it covers and the more even the effect will be. The drawback for that one, however, is that as there are more  fins, the longer it takes to travel from point A to point B. Along the way, the cooling effect could have already heated up. In general, the ideal number of fins should be between 12 to 16. Anything more than 16 would mean you’re most likely not getting the best efficiency out of your radiators. One important thing to note is that since this is a radiator, you shouldn’t expect this auto part to last for so long because heat wears car parts out fast. It’s important to find an efficient and high-quality brand so your flat fin radiator will have the optimum effect on your engine.
