Well, everything was working just fine on the car. I had my fan running with out the shroud for a while. Everything was good. I put shroud on tonight. Get everything else tight. Start it up. LOUD metal type sound. I stop the engine spin the fan by hand and there is no contact at all with the shroud. I take off the fan and I spin the "little circle thingy" at the end of the water pump that holds the fan and pulley(is it called an eccentric???). And I spin it and its squeeky as hell. I sprayed wd40 all over and it doesnt help. I think, well maybe its out of water in the pump or something and thats why it making this terrible sound. So I hook everything back up run it 5 minutes to get H2o circulating and it makes the same sound. SIGH . I dont get it. It worked fine before. If it helps- my temp idiot light has been going on all the time, even when I start it cold. I thought the light was screwed up, but I guess its telling me to go spend all my damn money and buy a milodin high volume pump I just dont understand why it would crap out after a fan change. BTW. I forgot to mention I took off this flex fan that was to big and put on the 4 blade fomoco with spacer so It would fit my shroud. Tell me I dont need to buy a water pump, please??? Well shoot mine as well put a new cam ,lifters , double roller chain, radiator, thermo, and electric fan while the pump is offThanks, Josh.
