Is the aux fan supposed to run with the engine off?
Mine doesn't, but will kick on as soon as I turn the key when the engine is hot. If it is supposed to stay on, then I need to check the thermo switches. Also, does the A/C switch for the aux fan sense the pressure of the system or the heat generated by the A/C system? The engine is now getting warmer than it should on a 10 mile highway run (200F). I'm thinking the T-stat might be hanging up, so I've ordered a 75 C t-stat from FastLane. I knew I shoulda done the T-stat when I was in there!!!
