I am trying to find my low A/C Port to be able to recharge my A/C and I am unable to find it. Could someone assist with this. My High Port is right off of the condenser.

Thanks,

For the 4.2L, check on the intake manifold side of the engine. I think there's a green cap on the schraeder (sp?) valve for the low side right next to the intake.

Okay, I thought that might be the one but it does not look like an A/C Port but it does come off of the A/C Tubing. It just seemed like it was plastic. I will try that and let you know the results.

Thanks again,

Is there anyone out there that would know where to get adapters/couplers that will work on the low side of the 2002 Chevy Trailblazer. The reason is that it does not look like a normal port. It is a plastic screw type or at least that is what it looks like. Also if anyone knows the adapters for a 2001 Chevy Silverado. The low side is much larger than the high side.
