"This last weekend It was in the 85f outside . temp gauge on motorhome held right at 190f with front air conditioning on . I shut it down after idle for 5 mins . and I noticed if I turn keey back on to part right before starter kicks in the front electric radiator fan kicks on . would this be another way to cool it more after shut down . You know leave key on for 5-10 mins . Theres some serious heat in engine compartment."
Mine's a older P30 (1989). The only electric fan on mine is for the dash ac and it's controlled from the ac compressor head pressure switch, if you are running the dash air and turn the key off and right back on but not restarting the engine, the ac fan in front of the condenser will come on till the Freon pressure drops below the switches set point, something like 250psi.
OK I will have a closer look at mine.
I was thinking its running even when air conditioners off . will let you know.
