Keith,

Thanks for the explanation. I will work on getting the gauges and get an
accurate pressure reading.

I have a 1987 Vanagon GL parts car.  One option is to put the more powerful
fan from it onto my 1984 Camper.  Do you think I would see a performance
improvement? ie, A/C shuts off above 55 mph at the same ambient temperature?

Anyone tried this? I am wondering how many parts from the newer system would
need to come over from the '87 to my '84.

Thanks,

John
