Just a question, does the engine cooling fan run all the time ?       The reason I ask is because I never paid it much attention until last weekend while on a trip, stopped at a rest area doing a walk around I noticed it was not running, I raised the rear cover and un plugged the relay and it came on (high speed) when I re connected it it quit. The water temp was @190 at the time. After setting there for a few minutes on high idle the fan came on (high) then when the temp went down it stopped.  Just wanting to know, it seems to me it should run all the time to cool the air to air cooler.   Thanks,  Ken    1998 coach 430
