Was going camping last week and noticed rising water temps and white smoke on acceleration.
Pulled over and found coolant leaking from between head and body of air compressor. Pulled supply line
from intake manifold and found some there also. [Think this was the cause of white smoke on take off]
Anyway, found and ordered new compressor and installed. All good for about 50 miles, then, same symptoms,
except air pressure was falling also. This time water was was coming from back of head gasket area instead of front.
I realize my air dryer filter is probably bad and needs replacing, but after installing new compressor, noted
pressures and recovery time after using brakes or leveling and all appeared normal. D2 valve seemed okay, running
about 125 psi before unloading. At $800+ for compressor plus core charge, would sure like to know what
caused same problems on two compressors. By the way, previous owner had also replaced compressor, do not
know why. To get home, bypassed water to compressor head, lit off gen and hooked up my cheap harbor freight
compressor to air system and made it back to the house. [not recommended if you have to stop very often]
Any thoughts or ideas appreciated.
