Welcome to FP. Yep, we like to see pictures!

Pontiac GTO

Thanks Frosty, Yes, I have a copy of the body and service manuals for the car and that's way the replacement is described. Was just looking for experience that might indicate there's more to it than described, and to see if there any 'gotchas' that might be good to know.

Hello Frosty - Yes, that's the plan. I was mostly looking for any experience that might validate my plan to get to the evaporator core by only removing the inner fender, and any experience with aftermarket replacements from someone like Old Air. Thanks for the input.

Welcome to FP. Great looking car, especially like the color

Congratulations to everyone who were selected for this year's calendar. Too bad everyone who entered couldn't have been chosen. Great looking cars!!

Welcome to the group.

After replacing my A/C compressor it seems that my evaporator core may be leaking. After using the A/C the last time I noticed that the condensation that dripped on the floor of my garage was oily and had a green tint, probably from the leak detect PAG oil. There's also residue around the drain hole along the rear bottom edge of the right front fender. After some research and review of the Pontiac service manual, I'm planning to remove the inner fender and replace the evaporator core with a unit from Old Air. Just wondering if anyone has experience with this and has any advice to offer. Classic Auto Air offers a service to restore evaporator cores and the housing, but they require a core that doesn't leak.

It was a great show this year and always fun to combine a Pontiac event with Cavanaugh Flight Museum. IMG_8774.MOV IMG_8775.MOV

Thanks Bear for the feedback. The factory fan and vent system will not help anyone in the back seat. Sent from my iPhone using Tapatalk Pro

After a few weeks of ordering compressors and trying them, I finally found a true bolt on replacement. Be aware if you're interested in replacing your old GM A6 compressor with one of the modern aluminum body compressors that the Four Seasons style from Summit Racing will require modifications. The muffler mounting on the back of the Four Seasons style compressor is higher and causes issues with the rear bracket that goes between the compressor and the intake manifold. While it physically fits the aluminum bracket on the front and the lower triangle bracket, you will not be able to use the intake manifold bracket or the muffler mounting bracket. I purchased a Pro6ten compressor from OldAir (manufactured by SunAir) , installed it over the weekend with new hoses and drier. Charged the system yesterday with R134a refrigerant and all seems to be good for now.
