A/C Pusher Fan...

So, many of you guys know the drill......sitting in traffic with the A/C on watching the heat gauge rise. Now, I never have overheated since putting the Champion radiator but it's nerve wracking in traffic watching the needle climb. Once I get moving....no problem it settles right back down to 180.

As a refresher.....I've got the Pro6ten compressor, new evaporator, condenser, hoses, adjusted POA valve for 134 etc etc. HD fan clutch. Shroud seals etc etc...
However, some of the reading and some seem to be of the opinion that the higher pressures of r134 vs r12 makes heat dissipation more of a challenge...blah blah blah...

So, I installed, or had installed because BDT (Big Dumb Troy....as yours truly is affectionately known) and electricity is a bad combination a 12" pusher fan in front of the condenser and had it wired to the compressor to run when the AC is on. I figured, I'm out 60 bucks for the fan and an hours worth of labor by my buddy Rob at OS Performance to wire it up.

So far. So good.

Driven it for a few days now......sitting in traffic with the windows up and the AC blasting the needle sits at 185.

How cool, indeed.

Cheers,

Troy

Anyway....just thought I'd toss that out there

Troy, that's excellent that the AC pusher fan fixed your problem. Post pics when you get a chance!

That is what a local AC shop recommended that I install if I were to swap to R134A, but that was to address the higher head pressure that would occur in 100+ summer temps. They explained that R134A could go over 300 psi with those ambient temps and blow out the compressor front seal. The auxiliary fan would keep the temp (and pressure) down. But they convinced me that R12 was the way to go as it was still readily available and wasn't as expensive as it once was after the ban.

Anyway, glad you and your engine are staying cool.

To do again, Ken, I would have stuck with R12. That’s another story for another time over a frosty beverage as it was a huge Urinary Olympiad with the shop I had install the AC bits and pieces.....

Live and learn

Cheers
