How do I reverse it from PUSH to PULL - Page 2

You've got more than enough wiring help, but when I did this many years ago I have the fan blowing out. What goes out has to come in so you get nearly twice the flow of the fan plus the engine draw going through the condenser. Airflow through the condenser is essential to have it work properly. Now there'll be whining that the engine will be starved for air, but the intake area is too big and the resistance too low to make any difference.

Glad its working, english (puncuation) was never my strong suit in high school.

Engine won't be starved it will get air from somewhere else but the fan will cancel out any flow in up to the velocity that the fan is flowing within the effective capture radius of the fan net you less air flow overall (fluid dynamics)

It may be fluid dynamics to you, but what you said doesn't make any sense. The fan covers about half the condenser area so it will flow out where the fan is and in the other area (no fan) it will flow it. It works!

If you think so. It makes perfect sense. Bye

My car runs very cool, today I drove a 90 mile round trip it was 110 degrees here in Phoenix and with the fan pulling into the engine bay with the fan blade reversed as it should be for a puller the vent temp was 57 degrees and the temp gauge never went above 7 o'clock on the gauge, it used to hang at 8 o'clock.

A 53 degree differential out the vents compared to the ambient temp is not bad for the 30 year old girl.
