Because of the high temperatures under the hood, it's common to see temperatures well over 300 degrees. You'd need something to keep you cool if you had to operate in those conditions—that's what coolant is for.
Coolant, also known as antifreeze, is a heat transfer fluid that keeps an engine's cooling system lubricated and cool (and prevents freezing in the winter). Coolant circulates throughout and around the engine, collecting heat and returning it to the radiator to be dissipated into the air.
The thermal cycling process continuously occurs as the car is driven. Over time, coolant picks up pieces of rust and grime, and its ability to keep the engine at an acceptable temperature deteriorates.
A coolant flush should be performed every 30,000 – 50,000 miles. It's best to have a trained technician conduct your car's coolant flushes.
They can not only remove old coolant safely, but they may also help identify any underlying issues such as leaks or indications of overheating.
When your car's engine overheats, it can cause major damage and result in expensive repair or replacement. Help avoid this situation with regular coolant flushes.
