Any tips and tricks on '95 compressor/drier/orifice tube replacement?
A/C started losing performance at the end of last summer. Along with a long list I decided to check it before this summer....
After the temp got to about 95 I decided to check the low pressure side. I bypassed the pressure switch, and the compressor is locked solid. The new compressor warranty is only valid if the accumulator drier and orifice tube are replaced, so I'm doing all three.
I've seen and been advised that using a flush cleaner and blowing out all lines with compressed air is a smart move, so I will do so. I didn't really consider if the condenser could be cleaned easily, but will look at that as well. Does anyone have any other suggested work be done at the same time, or is the current course a safe bet. If it involves more time and $$$ to do it right I'd rather take that route.
The only specific question I have for now is on the fixed orifice tube. I assume (and I say that with risk) that the line coming from the evaporator is fixed, and the orifice tube is the external part only.
Another concern I have is having heard that underdrive pulleys and A/C compressors do not like each other, and using the pulleys can reduce compressor life. I had UDs on for three years before I had any problems, and it doesn't make sense to me, but I'd like to hear any expert opinions on this...... (the peanut gallery opinions are already covered
)
TIA for any help.
