the pusher pushes the air through and the puller sucks through so they both flow towards the car, which gives it much faster wind speed = more cooling. i will try and unplug the pusher and see what that does for a while tho, but i am almost 100% sure it wont change much.
what i will do is get a new thermostat, put that in. replace heads with another set i have. and try again.
TRUST NO ONE. DEPEND ON NO ONE. PEOPLE ARE INCONSIDERATE.
