Air Conditioner Repair ?'s
I have just replaced the compressor for my air conditioner. clutch was o.k., also all new belts. added 6 cans of 134a coolant and 1 can of oil. (this is for a 1980 winnebago, 440 dodge). The thermometer reads 68 degrees at engine idle, out of the dash. Seems to me that this is too warm yet. I don't see fluid in the glass eye. What temp. should it get to? What else can I do? I am going to go for a trip around town to see if running at a higher rpm will do it. If not I guess i'll add more coolant. Your imput is very much appreciated,
Answer:
If you don't see any bubbles in the site glass you may have already over fill system. Suggest you check with A/C shop for correct filling directions. Have not personally changed an R-12 system over to R143a. When they first started doing change overs you had to also change the hoses, but from what I have read lately that may not still be true. Also did you use a vacuum pump to remove the air from the system and any remaining R12?
