Has anyone tried rebuilding a vacuum actuator for the AC system?

Im taking a stab a replacing the diaphragm, which is completely destroyed.

As replacement cost for the actuator are in the $80 region and I need 3. 

Ive managed to open one up (yay grinder).

I'm looking into different rubber sheets to just make a new diaphragm. 

Then reseal the actuator. (thatll be fun)

Keep us posted on how this repair works out for you
I do not ever recall someone trying to repair one of these Vacuum valves --and on here a few times daily since 2006
I need two valves and will be fixing my confort control in the near future myself
The key may be getting the --correct blader material
The major issue is --you will not know how your own design might hold up --for the long haul -and you really do not want to redo this job again after just having had the entire CC system apart and then back together
Just that may justify having to go for the expense of the new valves
Redoing the CC system is very time consuming and expensive but OH what a nice thing to have working to enhance the rides pleasure


I don't think they are 80, I thought closer to 50. Did you check all three with a vacuum hand pump? I don't known if the one under the hood is rebuildable. Its plastic face gets destroyed by the under good heat and oils. 

Ive removed all three. The diaphragm is essential GONE. Just remnants left behind. I have a commercial version, there are actually three of these things under the hood. They are aluminum. No plastic that i know of. 

I do know i have seen many 20/80 Vacuum valves with a white plastic fronts mostly on the passenger side heater box under the hood
I am sure that is what Clovis was talking about


Ahh commercial car. Its always good to post what kind of car you have and also model and year.

I removed the front cover to change out the timing chain & gears all that went pretty well when I put the cover back on I put in a fresh oil filter ,filled it up figured it would be enough to prime the oil pump when I started the car .Fired up the car and heard lifters rattling, So I shut the car down right away. So I removed the oil filter housing, and poured oil down the neck of the oil pump housing filled it up and filled up the filter put it all together and fired it up and same…

Caddy members, I’m upgrading my 64 2-door coupe deville.

motor guy lost my block (machine shop went under) so I’m replacing motor & tranny with LS conversion. I have motor parts (other than block) for 429, rebuilt transmission, converter, and too many other motor parts not needed with fully dressed LS going in.

Email me (Tom.reichenberger@ipsper.com) or call me (210-739-4854) if you’re interested…..I live in San Antonio, TX.

thanks, TX…

While working on my trunk lock on 64 Cadillac, I mistakenly closed the locking mechanism while the trunk was open.  Is there an easy way to manually release the lock back to the open position?


Fuel Pump Failure

Posted by Jon Shields on August 6, 2022 at 6:48am 4 Comments


I'm located in Melbourne, Australia and my 64 sedan de ville is stuck in the garage due to failed mechanical fuel pump. The first after market mechanical fuel pump lasted a few years before it failed & left me stranded 5 hours from home. A hire car and tow got us home. On inspection, I noticed a valve not seated within the housing. I was optimistic, pressed it into place and assumed the pump was good to go. But alas, no. From what I can now determine, the diaphragm pushrod…
