A/c r-134a Civic LX 01
 

I need to recharge the refrigerant on my a/c. I am just trying to figure
out which side is the "low side." I believe it is the cap that has the "L"
on it. However, I am just being careful. It was black on my 96 Civic.
Also, what psi should I charge it too. The manual only states grams of a
full filling.

Thank you
