I have a 1986 2.3 16 valve that has been converted to the r-134 refrigerant. It was done according to M-Benz specs and doesnt leak at all. My question is how much of the r134 should be placed into the system. The r-12 recharged at 3 lbs. Now, there is approximately 4 lbs of r134 in the system. It blows cold air, not as cold as the r-12. My question is, do you think that too much of the r134 was placed into the system?
I know that convrsions like this only need like 85% of the original capacity.
