Yes I added oil and coolent. Well tride to add coolen but built up to much presser then. Now someone has bipassed heater core allso


It sounds like too much oil, do you know how much you put in? Bypassing a heater core will not cause any A/C pressure problems. Just a cold, frozen or damp car in the winter.

4oz. Oil. Also freezes over. Cant get right pressure. To high but shut car off for min start up and pressure to low


May have a clogged orfice tube filter this filter is inside of the high side of A.C system ( the small line ) you will need a line disconnect tool to separate line and filter is inside.
