OK, bear with me for the scenario:
2 weeks ago the stud for the serpentine belt tensioner snapped and the belt came adrift. I got the truck home, replaced the stud and the belt as a matter of course. Belt was really tight to get on (right one chosen from measurements and VIN) but I assumed it was because it was brand new.
Had some squeaking after a few minutes of running but nothing too bad so I put up with it until I could get round to the penny trick which I assumed would be the problem.
Driving locally this week, and the temp gauge seemed to be all over the place, almost like there was a dodgy connection. But the main thing was the heater blower was not even warm. Engine seemed to run fine, so I carried on. On the way home, the needle moved up a bit then towards the red, but this time it seemed to stay up there. So I pulled over and stopped the engine. I gave it 10 minutes to cool down, checked the water (which was low), topped up the level and tried to start her. It would barely turn over.
My first thought was it was nearing seizure so I left it alone and called the rescue boys.
I had 2 thoughts as to the problem:
1. Big airlock causing the lack of reading on the temp gauge and also overheating.
2. Water pump foobarred causing no cooling, but would not explain apparent water loss (unless airlock as well)
I took the water pump off and although a little on the rusty side, the vanes are still connected to the shaft/pulley and there is no telltale of water from the weep hole underneath.
Also, in the process, one of the long studs holding the pump and alternator/steering pump bracket has sheared!
I checked manually for compression and it seemed good, so I attempted to turn the engine on the starter with the injection pump solenoid disconnected and it was fine, so I reconnected the solenoid and the engine started fine. I have checked for water in the oil and there seems to be no sign of it.
I would appreciate any feedback on what may be/have been the issue, and also any advice on removing the support bracket/pump carrier.
Sorry for the life story but it saves lots of questions after
Thanks in advance guys.
