Re: Can an AC Installed make the engine run hotter than before?

Yea, I guess most are right with not having to worry about boiling over.

I don't think that the radiator shops/vendors will say for positive that they would take it back if it doesn't work.

Think I am going to install a tranny cooler and get that out of the radiator. Every 20 degrees cooler a tranny can run will make it survive longer.

Who knows, maybe that might lower it 3-5 degrees too.

Thanks everyone for the replies and suggestions. Much appreciated.

If you add a tranny cooler do not route it solely through that. They are auxiliary coolers for a reason. Adding one is a great idea, but also keep the lines running through the heat exchanger in the radiator as liquid dissipates heat more efficiently than air.

110% You'll burn up your trans if you remove it from the radiator! But do add one. I added the heat exchanger type. It doesn't need to be mounted where it can get air flow, but I put it where it could anyway...

I added an aux cooler to my truck like 8 years ago. I've put over 40K miles on my 700R so far.

This was just a mock up pic, it's installed on the front cross member:

+1. You also get the added benefit of at least an extra quart of transmission fluid running through the system...
