60,000 miles on it, I do drive with a 45lb plate on my gas peddle so chances are it’s really bad but here’s what it does:

2 miles and it’s hot hot
I can’t tell if water is moving in the system
The purge line isn’t clogged but I took off from the reservoir end for 5 seconds and nothing came out

The thermostat is good for sure, the purgeline bolt is clean, it has plenty of coolant... it’s got to be the water pump right??

Water pump or the water pump tensioner pulley has seized and ruined the entire drive system. Plenty of threads on this common Northstar problem.

Coolant level is half full, ambient cold.

Maybe someone put some sealant in the coolant

the radiator may be clogged
the thermostat may be broken or missing
leakage through the water pump housing seals
tank cap damaged

a lot of things can be
