Thanks for the replies so far. Stocker thanks for the explanation it helped. But as far as the problem it must be something to do with the fan, and yes I have a fan shroud, I will try to check it out more thouroughly tomorrow. It needs its coolant changed, seems like more water than coolant

could that have anything to do with it? I wouldn't think so, if that was the case it should run hot all the time. right?
