You'll definately want an airflow source for the hot
side of the peltier that comes from outside the engine
compartment and exhausts to outside it too.

You'll also want a LARGE cooler block with a very long
or otherwise high area path for the water to flow
through so it can shed as much heat as possible.

They're not terribly efficient and a lot of the input
energy goes to waste as heat out the hot side. They're
much better heaters than they are coolers.
