Good to know that it is alright, but can you help me understand the setup a bit?
Is there a separate fan on one side and if so, how is it different than the radiator fans, etc?

I am completely ignorant when it comes to this!


Much appreciated!

I was told that the fan on the passenger intake vent is for cooling the exhuast. The front radiator fans work to cool the entire car's engine. Hope this helps.

Hi,

That's not quite correct. The Exhaust runs on both sides of the engine and consequently the car. The Fan is properly called the Engine Compartment Fan and is controlled by the DME from signals it receives from a Temperature Switch mounted between the #1 and #2 Intake runners. It's job is to control the temperature inside the engine compartment, not specifically the exhaust, and will usually, but not always, activate if the Engine Compartment temperature exceeds 180°. Hope this helps...

Happy Motoring!... Jim'99
