I have a 93 chevy p30 454 bb with tbi.I would like to try and recharge the ac.Can someone tell me where the low side valve is located.I know i have one valve under the hood and one on the backside of ...
The low side has a bigger hose than the high side...The charging hose on a can of refrigerant will only fit on the low side...if you have a manifold gauge set, the low and high sides are different sizes so they can't be hooked up wrong...I'd recommend you find a qualified shop to do the work (find the leak, fix it, and recharge)
