simonrac Posted January 9, 2005 Share Posted January 9, 2005 Man I hope one of you guys can help me. I've been trying to figure this out for two weeks. I've got a 98 gs400 and the radiator fans don't cycle on and off, they run constantly on full speed and eventually they drain my battery, especially if i'm driving at night with the wipers on. Please HELP!!!!! Quote Link to comment Share on other sites More sharing options...
92Lex Posted January 10, 2005 Share Posted January 10, 2005 Do they turn on as soon as you start your car? Quote Link to comment Share on other sites More sharing options...

mehullica Posted January 11, 2005 Share Posted January 11, 2005 Is the radiator temp sensor plugged in? It's on the bottom tank on the drivers side. Quote Link to comment Share on other sites More sharing options...
