So since the biggening of the summer I have noticed that when my radiator fans come on my oil pressure drops below 1bar causing the oil light to come on when im at idle, if I rev up the engine then Im fine. this only happens when I have been drive the car in hot weather for approx 30mins, Is there some kinda sensor that is bad or is something wrong?? The car idles fine approx 900rpm. I think the fans are making the idle drop and causing low oil pressure. Whats the fix??
