Re: Old school AC system compressor burned out

If memory serves (and it has been quite a while), the Compressor Thermal Limiter Switch on a VIR system from the early to mid 1970's opened with a pressure anomaly on either the high or low sides. Once it opened, it couldn't be re-set and had to be replaced, like a fuse. I remember changing those sw...

Re: Vintage air monster condensers

A search resulted in one heat-transfer products manufacturer who produces all-aluminum parallel-flow A/C condensers in 18 mm (0.71 inch) and 25.4 mm (1 inch) fin depths, probably in whatever length, width, and connections that you're looking for.

Re: Old school AC system compressor burned out

It has been quite a while since I worked on or even saw a GM VIR system. If you want to take a chance, you could disassemble the VIR and replace the desiccant bag yourself. Desiccant kits are available in the market. Better yet, I think, is to purchase an entire VIR unit that has been rebuilt by a r...

Re: Old school AC system compressor burned out

I'll take a guess about the thermal limiter: If it was the original part from 1976, it might have "silently" failed at some point, resulting in its inability to open and protect the compressor when something went wrong with it. Also, you mentioned that this VIR system was converted to R-13...

Re: 06 Tundra not taking A/C charge

I forgot to mention this earlier, but your 2006 Tundra (4-door model) takes 21 ounces net weight of R-134a and 7.75 fluid ounces of PAG-46. The 2-door model takes 23 ounces of R-134a; the oil amount and type are the same as the former.

Re: 06 Tundra not taking A/C charge

First thing is, don't jumper anything. If you run the compressor without a proper refrigerant charge, doing so will starve the compressor of oil and quickly destroy it. It sounds like you're only reading the pressure in the refrigerant container. How are you attempting to charge it, by means of a Ma...

Re: Nissens AC Diagnostics

Generally some good servicing tips from Nissens, and I agree with the exceptions and recommendations of what tbirdtbird said. Kinda' hard for those of us in the USA to relate to Celsius and Bar, though. As for pressure/temperature charts, I hardly use them at all and wouldn't put too much "stoc...
