Car overheats after changing water pump
I have a 80' Chevy Citation X-11 (yes, a
Citation, lol) for 20 years now & have never had
this issue.
My brother installed a new water pump
because the old one was dripping a little & the
temp. was just a tad higher, but not
overheating. About 10 min. after he installed it
the temp went to the red zone. Changed out the
thermostat, no change.
Radiator & heater core hoses stayed cool for
the 2 days my brother was trying to figure it
out. He did take the radiator cap off and bled
the system for air, no change.
After sitting a week, I bled the system again
and got the heat to work and hoses got warm.
Another person came out today & took the
thermostat out and turned it around the other
way. He thinks it was in wrong, still no change.
At first the radiator hose didn't feel like there
was water in there at all, then after awhile it
filled along with the heater core hose. Still no
change. They don't know what's going on.
All I know is that it never did that till
immediately after the water pump was
installed. I double checked that the parts store
gave me the right pump.
The car had been sitting mostly for the last 2
years. I drive it about once a month. A truck
going thru a red light hit it hard on the quarter
panel and it has a loss of power going up hills
but don't think that has to do with the
overheating.
Gotta get the emissions & plates renewed this
month, so gotta get Old Red back on the road
soon!
Thank you!
