Back to my newly acquired 1989 B250 again. I find that when I'm going up a long hill, even at city speeds, the temperature gauge starts to creep up.
Other than hill climbing it seems to stay pretty steady, even at highway speeds.
When I get to the top and can coast along it goes back to normal.
This one is new to me so I'm looking for a list of most likely culprits.
Could even be a sensitive temperature gauge I suppose.
I did a flush and fill of coolant a couple of days back and I ran and flushed a non-acidic prestone cleaning solution to take out any sludge it could.
I leave tomorrow night to drive across the continent to California and at the moment I figure some of the mountain passes might take a few hours to cross if I have to stop several times to keep the temperature down.
The fan runs and the water pump runs quietly.
I'm thinking of picking up a water pump tomorrow if I can get one just in case it overheats and I can't find a mechanic on the weekend. Unless the bolts are seized I might be able to swap it out in a truck stop parking lot.
Would running the van in a lower gear up a mountain pass force the pump to run faster and keep it cool? It just seems to heat up when it's put under pressure going up a hill.
Any experience with this problem?
Thanks.
