What heat exchanger is this gents?
It sits directly under the engine, right behind the front bumper.

It suffered a bit of damage and I would like to replace it asap.


Can you tell me what system is this cooler for?

 

That's for the intercooler.

 

Thanks! I found the part, is seems that it is an auxiliary radiator.
I wonder what is the function of this auxiliary radiator, since the main radiator is fan cooled. Does it support the main radiator in keeping the coolant level temp down?

 

It's for the intercooler, which is air-liquid, and circulates separately from the main engine cooling. I've never removed one but since I have never seen a separate reservoir, I assume it shares that with the engine cooling system.
