yeah my truck is from georgia now living in CT and already stays in that first quarter. I'm pretty sure someone already switched out the thermostat before I got it. I'll check the hoses and cap though. Has anyone ever done a water pump before on this engine? what's involved? Thanks for all the help so far. :great:

Sure doesn`t hurt to have or borrow that special wrench to get the fan off. I have used a chisel and hammer but the wrench would be easier. With a small deposit O`Reilly`s may have one that you could borrow for a few hours that is if theres a store close by.
