Is this right? My friend told me the other day that the heat inside your car when you turn on the heat is caused from the engine heat released to go into your car and therefor making your engine bay cooler? Is this all correct or what? It makes sense to me. thanx.

The heat from your car is from your engines cooling system. In essence the heater core is a mini radiator. Yes it does release heat from the cooling system, but this does not lower underhood temperatures.

It cools of a little bit for a little while. Turning your heater on will circulate warm coolant through the heater core, and doing this will flush cold coolant that has just been sitting in the core through the engine. So, the slight drop is from cold coolant flowing through there, but it wont last long as the engine will warm that coolant just like the rest of it.

" think it cirulates through the heater core at all times its not a trap door system...the only thing that may MAY help with cooler temps is the fan blowing the hot air into your car and getting it away from that mini radiator...but thats minimal."
This is not true on all cars, some have vacum valves to stop coolant flow when the heat is off.
