A/C condensor pusher fans - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**Stocker** · 05-24-2018, 05:13 PM

Had a third shop work on my A/C and it finally seems good.... with one exception. I was told I need a couple pusher fans in front of the A/C condensor, because at low speeds (or at idle) there's virtually no air passing through the condensor. It's in the stock position but sits too far from the radiator. With a big gap at the top and a smaller gap at the bottom, most air to the radiator is bypassing the condensor.

If any of you have added pushers in front of your condensor, what did you use? I searched a bunch of threads but didn't find what I'm looking for. Summit has thousands of fans and it's hard to know where to start. Thanks for any help!

Nevermind..... Found 12-inch Hayden 3680 fans locally, did some more research and decided to mount a pair of them to the condensor. They'll be triggered by the hot lead to the compressor, using a relay & fuse of course.

I have a big pusher-puller sandwiched between the radiator and compressor. Definitely helps with engine cooling at hot idle with the AC on, and the AC works, so I guess both work!

It'll still slowly climb in temp at idle on a hot day though.
