the water pump was making alot of noise,like a bearing,it was rattleing.the shaft "wobbeled"[is that how you spell that?]a good bit.when i put the new pump on,the sound went away andi thought i was ready to roll. it doesnt seem to heat up real fast.the radiator is 4-5 years old.the temp rarely reached 1/2 way before. i cant imagine its the radiator all of a sudden.its like it heats up but wont cool back down where it used to.i did scrape some gasket off,a little permatex too.whats your thoughts on a thermostat problem,my housing is leaking a little anyway
