Overheating. Had fan clutch and thermostat replaced. Mech said waterpump is fine. Had a cumbustion test done, heads are good. No visible leaks. Just ran it for 45 min and a 5 run. Heat on full blast. It is 90 here. Turned on ac and the heat gauge went up to holy ****, shut it down. Turned heat on b4 shutdown and gauge went back down. I think pump is bad. Thoughts? 2004 se with 60,000 miles. Trying to sell but will not give the next guy a headache.
On what basis did the mechanic say the pump is fine? If he took it out and looked at it
and the impeller is intact, etc, then it can't be the pump. If he said it's fine without doing
that, then it's still possible it's the pump. But pumps usually fail via the seal leaking,
not the impeller disappearing, but the latter has been known to happen. Also possible,
but not likely, that the new thermostat is bad. And like Dean said, a collapsing hose is
a possibility too, as is a plugged radiator.
Hoses new and good. There is no way the mech took off the pump to look. I am betting worn blades.
How much for a pump inxtalled? 300? 800? 2004 xterra with 60 for sale. Not a stain inside. Look marketplace facebook. I do not have an account.. My wife posted it.
I have a hard time believing a water pump is bad after only 60,000 miles on a modern vehicle. How about the
radiator cap? Maybe flushing the radiator would be a good step before replacing anything.
A search turned up a few people who had a transmission fluid/coolant leak in the radiator.

Did the mechanic do a pressure test on the cooling system?
Pressure test done. Called it a cumbustion test. ?
No. Different tests. A radiator pressure test:

A compression test.

A combustion leak test.

I've never had to do these tests so I just know they exist.
