I was at the track and my buddy whos got a blown GT leaves his heater on but the car off while he's in line to run. Says it cools the engine down? I thought the heater core was separate from the engine? So is he just retarded or is he actually cooling his engine?

 

i know that it actually cools the engine a little when the car is running, but when the car is shut off, i have no clue

Well, he's not actually cooling his engine if its not running.

 

With the engine off it will only cool the tiny amount of water in the heatr core proper. Its a waste of battery.
