The engine in your car runs best at a fairly high temperature. When the engine is cold, components wear out faster, and the engine is less efficient and emits more pollution. So another important job of the cooling system is to allow the engine to heat up as quickly as possible, and then to keep the engine at a constant temperature. Every vehicle has at least one fan. That is how vital it is, but some vehicles have more than one to ensure their cooling systems are superb. There are belt-powered fans, electric fans, and AC cooling fans. Electric fans are more modern as they don’t have fan belts for you to keep a constant eye on. They are also quieter and consume less power than other fans. Primary cooling fan use a thermostatic control called a fan clutch to determine the right speed of their spin. The fan clutch signals the cooling fan to run faster when heat is accumulating in the engine and tells it to go slower or stop altogether when enough air is coming through the radiator. This renders the fan unnecessary. Cooling fans drain
