Had the most major problem of my 88's career. Water pump failed, throwing the pulley forward a half-inch, tossing the belt. My experience was: temp gauge pegged into red out of nowhere, steam into cabin and from under hood, power steering loss, clunking.
I got it to the shoulder of the interstate, realized the problem, pulled the belt off and let it cool down. The pressure bottle was like a balloon and it was blowing steam out of some fittings (like up the heater core area mostly).
I could only go a half mile at a run before it got too hot. Then I'd let it cool enough to try again. Eventually got it to a park and ride. My Dad was able to bring me a new pump and 195* thermostat + fluids, etc. I had the tools.
Finished up at about dark and drove it the last 2 hours home. It ran hot, but not overheating.
Before the failure, the system ran at almost a full notch under 210, staying there almost no matter what.
Now it got to that point, opened the thermo, then very gradually climbed up to 210. I threw on the heat the rest of the trip home and it sat right at or slightly above 210.
I think there is air in the system yet. No leaks have shown up and it was consistent in its temp, just a little high.
I did burp the system with the coolant temp sensor pulled from rear of block/ nose downhill/ fill bottle until coolant comes out/ replace sensor. I'm not sure I let enough coolant/air run out though.
Does that sound like the right line of thought? What else could cause this higher operating temp? The new thermo shouldn't affect it, right (it just opens at the right temp and the system does what it does after that-right?)?
Oh yeah, so the history now is: new hoses, bottle, freeze plugs about 2 years ago. New fan clutch a month ago. Temps stayed just over the notch before 210. Now, new water pump, new 195 thermo and temps to 210 and over.
