    Why is my AC box condensing and dripping?

    Both the car and the AC have run MUCH better since I evacuated and replaced the dryer. No more getting hot in traffic/at stop lights and AC is blowing cooler. However, and this started before I made the repair- The bottom of the heater box is getting super cold, almost icy to the touch, and...

    How many 12oz cans of R134a in a 73 RV2 system?

    A/C receiver -dryer popped on 134a convert system. Need special?

    Stock 318 runs 30 degrees hotter with AC on- is this normal?

    Last year I put in a mechanical temp gauge (factory gauge was horribly off calibration). It runs at 165-170 degrees. I know, but I checked it against an infrared thermometer and it was within 2 degrees. So anyway, If I run the AC (all stock RV-2 but with 134a professional conversion), it gets...

    small block H2O pump bolts into water jackets

    Hey guys, I looked through six pages of search results and cant find it. I have a 67 FSM, a Dakota Haynes and three Motor's manuals plus 12 pages of googling. Nothing. I swear I've seen it many times. Anyway, the first time I did the water pump on the Dakota, I put gasket sealer on all the...
