Just got this truck a/c comp. would nt engage so i bought one of those 18oz bottles of 134a with hose and gauge and with motor and a/c on max cool i charged it on the lo side and the comp came on and off 3 or 4 times and at 45 or top of the green on the cale it says full is where it went. But it made a lot of noise for about 5 min and the quieted down and cool air inside. It has not been ran in a yr or more, do I need to add a couple of oz s of pag oil as its still a little noisy??
