Shroud And Fans:
    The fan and the fan shroud effectively drive the heat over and out the engine compartment rather than thrusting it into the front of the engine.

With excellent operating temperature management, allowable levels of engine temperature are stabilized. Investing in proper maintenance though will considerably benefit the ride and driving quality in maintaining the ideal working conditions of the engine.
