Locate the "low" pressure side and fill the freon while the car is in idle with the AC on high. Make sure you have the AC light on and try filling to 40psi, wait 24hrs then fill if you think more is needed. Remember if the clutch stops working then you have put too much. try discharginh from the high side slowly. GOOD LUCK
