Expansion/POA valve cover on a '65
Take a look at the attached pic, can anyone tell me what that cover is over the expansion/POA valve, I've seen other "65's with it but most do not have it, including mine. Was it for early/late cars, only cars with ATC? Anyone got one?

Most of those were broken / thrown out when removed for service. Can't give you a proper name.

So do you think every A/C car came with one in '65, what about other years, anyone know? They may have been a pita to r & r so people, auto shops, dealers just threw them away, they don't seem to be for any reason other than looks.

I'd say the have an inuslation quality also. Keep the POA valve cooler and it functions more efficiently.

I bought my '66 Grand Prix from Pete Klabo (Ventures Unlimited) in Oregon and I clearly recall him pointing out that the car was so original it still had the A/C cover fitted.
Why do they get thrown away??? I'd say it's for 2 reasons: they are a little difficult to remove & refit but more probably it could be that the mounting lugs fracture so they just break and the cover starts lying loosely over the A/C unit. My own cover has one broken lug (which I have repaired & strengthened) so I'm very concious it it brittle & old. Ian

AC Plumbing cover
I've never heard of the reason for their existence but I can tell you that they were installed on all fullsized AC cars both in 1965 and 1966. Not sure if they were installed later than these two years. Pontiac changed the POA valve configuration in 1966 and as a result the cover for that year is slighly different (less domed) than the 1965 ones. There is also a different part number for each.
I finally found a good one after searching for many years. The ears did get easily broken off and when I bought my car the ears on the evaporator case were all that was left. These covers are very difficult to find since most are damaged in some way. They are made of fiberglass and the engine heat after all these years have made them quite brittle. Hope that helps clarify. Brad Kline |

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
