McClare Posted August 12, 2007 Share Posted August 12, 2007 Anyone know what adapter you need to recharge the a/c on a comanche? My friend has one of those fill bottles but doesn't have the right adapter for it. It doesn't push the pin in when he threads it on Link to comment Share on other sites More sharing options...
Oizarod115 Posted August 13, 2007 Share Posted August 13, 2007 i think you have to change out all the seals and stuff in order to run r134a :dunno: never tried Link to comment Share on other sites More sharing options...
dfreeman616 Posted August 13, 2007 Share Posted August 13, 2007 the bottles you're referring to are r134a refrigerant, but our trucks came with r12. the adapters can be had at most auto parts stores, however you may need to replace some parts due to leaks. you also have to remove all the r12 before converting. while you can vent it to the atmosphere on your own, this is illegal and should be done by a licensed shop. the other possibility is recharging with r12 at a licensed shop, but r12 is considerably more expensive than r134a.

Renegade Posted August 14, 2007 Share Posted August 14, 2007 I just tried to convert my '89 to 134 & we found a leaking Schrader valve. Thought it would be no big deal except we could not find a replacement. Apparently they have been discontinued & the only solution other than a junkyard replacement(which may also leak) is a new aftermarket compressor. :headpop: Good thing winter is right around the corner.
