You can't do a direct drop in of 134a. At a minimum you need to replace
all seals and o-rings in the system. You also need to replace the oil
in the system with an ester type of oil.
Just today, at work, I receved a flyer on something called "Hot Shot"
refrigerent that is supposed to be a direct drop in for r12 (after
removing any remaining r12 from the system). I will be investegating it
further -- has anyone used this stuff in an automobile?? I imagine that
it is some sort of an HCFC blend. I'll let you know what I find out.
