Low AC Check Valve?

4 posts in this topic

I want to check my own AC coolant in my Spark. The kit I have says to use the Low valve, but I can only find the one marked "H" (high?). Should be a High and Lower valve. Where is the Low pressure valve so I can check my AC coolant?

I think it is up near the firewall, but don't remember exactly. I know it is definitely in the engine compartment and I've had a guage on mine in the past.

Please note the gauges on those cheap diy a/c recharge kits are horribly inaccurate. You should be using quality shop gauges that also measure the pressure on the high side.
