2. Is the heat not trapped between the underpan and the underside of the car body?

There is only one cat under the hood, and I had to cover this with fiberglass batting to keep underhood temperatures down to a reasonable level in the summer.

The heat is not trapped, because just as basjoos has mentioned, the heat travels through the radiator, through the engine compartment, and out the wheel wells. The heat can also exhaust through the slots next to the windshield wipers.

In my case, it can also exit just in front of the second catcon underneath the car.

In the winter, the engine heat is so low that I have a hard time keeping heat in the radiator, even with an almost full radiator block.

Jim.
