Hi, The Fans in the Bonnet do not run even after driving my car for more than 1hr or so. I'd noticed if the engine is hot it (FANS) would kick start by itself but now it is not starting. Any help appreciated. Regards, Javeed

The cooling fans will only work when the engine reaches a certain temperature. Under normal driving conditions this will not be reached as long there is sufficient airflow through the radiator, the cooling system is circulating correctly and engine heat is dissipating properly. When you are stationary or in slow moving traffic this airflow is reduced, and then the fans should be deployed when required to draw air through the radiator. If your car has air conditioning the fans should work when it is switched on. The A/C will not work if the fans don't.

The relay for the cooling fans is behind and below N/S headlamp. The engine ECM will switch the relay to operate the fans when the engine temperature gets too high.....
