Anybody had this issue? My coolant level is fine, my fan is working, no leaks. For some reason my engine overheats within about 10 minutes of starting it. From what I understand, it can't be the thermostat because it that were broken it would be stuck OPEN and flood the system with coolant.
Anybody know what it could be?

i havent had a stat stick shut, but it could happen. an other thing that can happen is the lower hose can suck closed, but it is rare. there should be a spring in the lower hose, but it can rust out, thats when the lower hose can suck shut.

 

It does sound like the thermostat is stuck closed.

 

change the t-stat first, it could be stuck. if that doesnt work it could be your water pump.
