heres the details:
1987 203k miles
stock except for the following:
converted the cooling system to this to eliminate the coolant bottle:
even has a over flow tank:
and its got a 3 row radiator.
so ive been running this system for a while now, with no problems at all.
so for a while ive been hearing a slight noise which sounded like a water pump going out. well recently the sound got louder, and my dad agreed that it sounded like a water pump so yesterday we decided to replace it. so it take everything apart, drain the system, go get the new water pump, then put it all back together. so i fill it back up with coolant, then started it up. it was immediately noticed that the sound was still there, so apparently it wasnt the water pump....weird....while idling we were going around checking for leaks, and could not find any. well we happened to look at the temp gauge and noticed that it was warming up quite quickly. soon enough it got about 210 degrees so we shut it off. so we let it cool off for a little bit and decided to drive it a little to see if things changed. so i took a quick drive around the block, and when i pulled in the driveway it was about to hit 260* so i quickly shut it off. saw steam so we popped the hood and found coolant coming out of the cap as seen in picture 1, and the overflow tank almost full of what looked like plain water...as opposed to coolant. What the hell? we replace a water pump and now it over heats? its got recently replaced hoses and a recent flush, so that shouldnt be the problem, and while we had the rad out we flushed it out, so that shouldnt be a problem either. one thing i did notice was that the aux electric fan did NOT come on at all. the sensor was recently replaced and it worked before the water pump replacement. and yes we made sure both the fan and sensor were plugged in.
So my dad and i are stumped. it over heats after replacing a water pump and now the noise we thought was a water pump is actually something else. what could this be? we took a stethoscope and listened to all the pulleys on the serpentine belt and none sounded bad.
any ideas????
