Re: {Chrysler 300} 64 K AC compressor

If it's a factory air car and all original components are present (not an add-on situation done by someone in the past), it should be able to work without overheating. If factory, there should be (or have been) a fan shroud in place? If fan was ever removed, was it reinstalled correctly so it is pulling air through the radiator/condenser and not on backwards? Was the radiator ever flow tested, cleaned out, etc? If water pump was ever changed, was it an A/C car water pump? They are different from non-A/C. Is fan clutch working properly, or maybe it's slipping too much all the time? How old is the thermostat? Is it opening all the way and as early as it should?

Lots of things to check, but they're all relatively simple and not costly to test/check.

I had my own concerns with my Hurst when I moved to Texas a couple of years ago, but so far all has been well except for the poor quality rebuilds I've run into with RV-2 compressors. The most recent one has been on the car for almost two years and no problems/leaks from seal have occured yet. I'm thinking seriously about mounting a more modern/efficient Sanden in place of the RV-2 if/when the next compressor failure occurs. I've seen quite a few Mopars with factory A/C down here, and most have been 'upgraded' to a Sanden unit as part of the R-134 conversion. Everything else looks stock and left alone, as someone (Old Air?) makes a bracket to mount the Sanden in the same place as the RV-2 sits.

I left the K with my mechanic for a couple months when I was away. He installed the new compressor and recharged with R134. Car overheated badly so me added a couple of ugly electric fans ( without telling me). It cools well now but chronically runs right up at the very top of the range on the temp gauge. He tells me the radiator must be bad....

Car lives in NY and it certainly has been hot this summer but that is why we have AC. Do the wise folks here have any insights? Live with it? Replace radiator ( seems ok to me)? I suppose I would be ok with the fans as car is certainly not perfect anyway but as they hardly work, more seems in order.

Thanks all

The eBay rebuilder certainly looks like a solid supplier. Good find.

I have batted 1000 with Original Air for various product and services, and my buds have all had good business with them.

Folks

I went to my mechanic to get our key updated to our 134 refrigerant and I was told that the old York AC compressor is no good. He told me that replacements were impossible, and that the best solution was to convert to a modern AC system. I have done that on my age, but this car is so original that I hate to think about tampering with that. On the other hand, it's sure nice to have air conditioning! I'm confident that someone in this small world of Chrysler crazies has had this experience too and has some wisdom to impart. Thanks in advance.
