Default a/c recharge

I want to confirm where the a/c recharge ports are located. My local garage where I have the oil changed etc was unable to locate the ports to do the recharge (there are not many SAABs in N/W Louisiana). The reason I am not taking this to my dealer is at this time I am unwilling to go to them since they seem to be below standards for SAAB repair (multiple trips for same problem + high $).

Any advice/help would be appreciated.

Loyal SAAB owner.

hi funsaabguy,

the aircon recharge points are located on the lefthand side of the engine bay if you open the bonnet, i think covered by a plastic cap.
There are 2 points for charging but im not sure witch one is the one you need!
easy way to spot them is they look like i big plastic screw cap, take cap off and you have a valve charge point.
Hope the helps

Sorry to bring this thread back to life but my dad gave me an aircon home recharge kit he had bought (r134a). The problem I have is the quick connector on the filling hose that comes with kit doesn't fit onto the low pressure connector on my car (if I'm at the correct port).

What I think is the low pressure connector on my car is like a large tyre valve with a green screw on cap, the high pressure fitting behind my grill is the correct type of fitting but is too large (a safety thing so you don't put pressure into the can and blow it up )

I am assuming the connector on the left of the diagram before is the low side (is rubber hose / the other connector behind the grill is on metal pipe so imagine it would be high side).


Hope that is kinda clear , so these are my questions.

Am I at the correct fill port (green cap inside drivers side wing)

Does anyone know what thread this port is and if / where I can get an adapter to go to the quick release type fitting?

Thanks.

I think you're toying with the wrong valve. The tire-like valve on a rubber hose with a green cap on the passenger side of the engine bay is a valve to the EVAP system. The low pressure A/C valve you're looking for is under the passenger headlight. You have to take the headlight off to get to the valve. It should be the same as the high pressure one. Do not connect anything to the valve with the green cap!

Thanks walmark -



Good job I wasn't in my normal 'you will fit on there' frame of mind took a step back and had the sense to pick the brains of the people on here.

I will have a look behind the light tomorrow in the daylight.

What is the EVAP valve for? Is the Evap for the aircon also gas filled? I was tempted to push in the valve stem to see if there was pressure behind it!

It's like when you see a wet paint sign or big red button - you just need to touch it.

Thanks again.

EVAP system is used to store gasoline vapors compressed during refueling. These vapors are stored in a canister (on top of the tank) and later slowly purged into the air intake for combustion via the purge valve. The nipple you found is a service port for that system. This is also why you will get check engine light when you don't tighten the gas cap right. It has nothing to do with the aircon though.

A general rule with car air conditioning and refrigeration systems is that the low pressure pipes are the large dia ones. the high pressure side the small dia pipe work. so if you have two car ac ports side by side with no colour coding then that may help.
