R134 with stock condenser. Will it cool or? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Should I put a parallel flow in? I'm doing a factory looking restoration and I'm doing some work to the rad support and now is the time to make the decision. I hear you can't flush parallel condensers. Im in Canada , not Arizona, so it gets warm but not blistering hot. Anyone our there with experience? I also have the poa recalibrate already and I'm using all new components and have a nos condenser.

My 85 will freeze you out . I converted to 134a with pretty much everything factory stock . Changed out the POA and pressure switch been 2 years since I had it done .

I use to convert them all the time in my garage work days. All you need is the R134 schrader valve conversion kit. Screw the new fittings over the R12 ones and you're in business. Take the valve core out of the R12 ones first.

Same with my '87. I did nothing except change the fluid type and it is perfectly fine.

Been 13 years in my case.
