I have a 93 caprice 5.0 305ci with only 82k miles on it. The original a/c compressor is finally going bad. Anyhow I need to figure out which compressor it has ltr4 or r4 and the I.D. tag on the top is worn out and unreadable. Is there another way to tell the difference between the two? Any help would be greatly appreciated.

Found this on the web:

Compressors are an essential component of air conditioning units. They compress the refrigerant's cold low-pressure gas to hot high-pressure gas before the condenser converts it to a fluid. AC Delco's R4 compressor is common in vehicle air conditioners, including many of GM's cars since 1984. The company markets a standard version and a smaller lightweight model. Besides the weight, the only significant difference between the two versions is that smaller model uses a six-pole electro-magnetic clutch instead of the four-pole clutch on the standard R4 compressor.


Looks like the LTR4 just weighs less. Ya learn something new every day.
