The engine cooling fan only works when had to help cool the engine. Therefore, a failure inside the engine cooling fan, relay or manage circuit is horrible information. Because it may permit the engine to overheat. The engine coolant sensor or a separate engine temperature transfer use to control the engine temperature. As a end result, the engine cooling fan does no longer begin until the engine reaches the average running temperature. Therefore, no extra cooling is needed whilst a chilly engine starts offevolved. The fan will then switch on and rancid to maintain the proper coolant temperature...
