Valve core

Barrnone on Sat June 21, 2008 4:55 PM User is offline

Year: 1995
Make: Chevrolet
Model: Tahoe
Engine Size: 5.7
Refrigerant Type: 134a
Country of Origin: United States

I noticed that the high pressure side is leaking at the valve core. I went to see if I could tighten it just for the moment and my standard r12/r134 valve core tool will not fit into the valve. Does this require a special tool? If so is the tool and valve core available from ACKits?

Thanks for all of the previous help.

Not really sure if the 95 uses the shrader valve or teflon ball. Can you see the valve, or a ball. If you can see a valve like a tire valve, it is most likely a big bore shrader valve which Ackits.com does have the tool. If you see what appears to be a ball, it's a replaceable service port. But, if only leaking very sow, try a new cap, as the cap is the primary seal on those..If it's leaking a lot, and past the cap, you will need to evacuate the system to change the service port. Let us know which you have...Hope this helps..

This valve core tool on the bottom of the page works with the regular and big bore valve cores.. But not with the teflon ball being used on most high side systems today by the big three..Hope this helps..

Chick,

That is the valve core tool I have and it does not fit into the hole in the service port. It is leaking pretty good, when you take the cap off all I can see is liquid bubbling off and the system is low enough now I don't want to use it. The low pressure port is at an awkward angle, I will get a mirror out and see if it looks like you describe. If it is a replaceable service port, it sounds like I can get that from ACKits, right?

Thanks
