Why do I need to flush antifreeze\coolant?

Why do I need to flush antifreeze\coolant?

Antifreeze (also known as engine coolant) has three major functions.  The first of course is to cool the engine down.  Without antifreeze your engine will very quickly suffer catastrophic damage.  The second function of antifreeze is to keep the coolant in the engine from freezing (It's like the function is right in the name!  Weird right?).  If the coolant were to freeze inside the engine it would expand and crack the engine on the inside.  The third function and one of the more important ones in our tropical climate is corrosion protection.    Degraded coolant will negatively affect all three major functions of the coolant.  Whenever antifreeze gets old it will break down and form solids in the engine.  This looks like either murky coolant or gunk buildup inside the radiator.  These solids will do massive amounts of damage to the engine seals and moving parts like the water pump.   A coolant power flush will remove m ... read more

Why do I need to flush my transmission?

Why do I need to flush my transmission?

Transmission fluid has many functions.  The fluid is used to put pressure on certain clutches and plates inside the transmission which causes the motion of your vehicle.  It is also circulated through the radiator to cool the transmission.   Over the life of a vehicle the transmission fluid is put through large amounts of abuse.  Whenever transmission fluid breaks down it loses its ability to cool the transmission properly.  It will also pick up debris which will be circulated through the transmission causing damage to the moving parts inside the transmission.   A transmission flush will remove the debris and gunk build up inside your transmission and radiator.  It will also replace the old fluid with new fluid that will protect the moving parts inside.  Just changing the transmission filter and refilling the pan will only remove about 25% of the old transmission fluid leaving a large amount of fluid inside the torque converter and radiator ... read more

My vehicle vibrates when braking! Help!

My vehicle vibrates when braking! Help!

Ever wondered what is happening when your car vibrates when you hit the brakes?  When you operate your brakes it creates an immense amount of heat in the brake rotor.  This heat can cause the metal to warp especially after hitting a puddle with some cold water in it after the brakes are already hot.  When the metal warps it can cause uneven contact between the brake pad and the brake rotor.  This is felt  in the steering wheel if it is your front brakes and the body of the vehicle if it is your rear brakes only when the brakes are applied

Why are my brakes squealing?

Why are my brakes squealing?

There are many causes for brakes to squeal.  We will cover the three most common in this article.   The number one cause of brake squealing is worn brakes.  The brake pads of today come with a small piece of metal that hangs off the side of the pad which is designed to squeal whenever your brakes are thin enough to need replacement.  It is a nice design feature that allows you to change your pads before any damage occurs to the brake rotor.   The second most common cause of brake squealing is poorly designed cheap brake pads.  These "economy priced" pads are made of cheaper material that creates more heat and vibrates across the rotor causing a loud squealing noise.   The third most common cause of brake squealing is glazed brake rotors.  When braking, the brake system will build up immense amounts of heat that cause the surface of the brake rotor to become very slick.  This slick surface will cause even the best of brake pad ... read more

My Check engine light is blinking! What does that mean?

My Check engine light is blinking! What does that mean?

The check engine light is designed to turn on when there is a fault in your vehicle systems.  When it blinks the fault has become detrimental enough to cause damage to the catalytic convertors.  Most often the light will blink due to a misfire significant enough to cause excess amounts of fuel to dump into the exhaust system.  This excess amount of fuel is then burned in the catalytic convertors causing them to superheat.  This can cause the substrate in the convertors to melt which will completely ruin the convertors.  Due to the expensive metals that are used in the catalytic convertor this can be a very costly repair.  The sooner the misfire is corrected, the more money you can save in other repairs that can be avoided by not procrastinating.
