Complete Coolant Flush & Refill - $89.99

The coolant system is an area that can often be overlooked. When you think of the stress that the coolant goes through every day, it's amazing it lasts as long as it does. Imagine a liquid that can be heated to 212-235 degrees and stay there as long as the engine is running. It would seem that staying at that heat, it would separate into different components. Well, actually it does. This takes a while to happen though. When different components are separated out of the coolant mixture, they must collect somewhere. Most of the time it is in the radiator and the heater core. Over time, this will restrict the flow of liquid through them. It can even cause them to corrode and start leaking. There are inhibitors that are added to antifreeze, but over time, they will dissipate. This is when the coolant should be changed. Antifreeze also acts as a lubricant for the seals in the water pump. If the coolant looses its lubricating properties, the seals in the water pump will fail. Then coolant will enter a bearing and cause it to fail. That is when you will see a coolant leak from the water pump, and it will have to be replaced. Old coolant can also cause the hoses to break down. Another problem with a cooling system could be a bad radiator cap. The cap should form an air tight seal to the opening of the radiator. If the seal is bad, it can allow coolant to leak past it, or even worse, allow air to enter the cooling system. When air and water are present against iron, it will cause rust. This rust will usually accumulate in the bottom of the block. This will degrade the coolant's ability to exchange heat from the engine. Is extreme cases, it can case the engine to overheat. All of these things added together make for a nightmare when it comes to repairs!
