pusher vs puller fan

My car is N/A, so heat is not such a concern as turbo.

The Hayden fan is only rated at 1100 CFM. That is what I am using too. Mounted to the back side of the radiator.

The boiling sound is normal when you shut off engine that is pretty hot. Its boiling the water, and the cap is letting it over into the bottle.

I always have my A/C on here in the desert, so my 2 little factory fans also run, which helps keep it cooler.

I run a 180* thermostat, which won't prevent over heating, but does allow it to run cooler if it can. Better than keeping the temp up to 195* minimum.

I also added a large (12"x15") transmission cooler right in front of the radiator (mounted to it actually), between the radiator and the A/C condensor. I removed the small 3/8" coolant by-pass hose (below the thermstat) and ran hoses out (under the afm)to the new cooler.

I calculated a 40% radiator increase.

It always runs about 1/3 on the gage, and never have the boil over sound anymore.

50/50 antifreeze. New cap.

If I were to ever need a new fan, I would get this.

You may need this. Or do a search on this forum for electric fans others have used.
