If the lower hose never gets hot it's the tstat 90% of the time.

How long were you overheating for? Were you towing?

Not towing. I noticed it when my engine started surging. Looked at the cluster, check engine light on and the temps were red lining.
I've also removed the belt. This is a 2003 silverado with a 6.0.
The waterpump pulley is not wobbly.
It's tripping me out though. One of the hoses to the heater core was off for some reason. Even if that was the cause, why haven't i fixed it yet? Crazy.

Tstat makes sense if you're sure the water pump is working.

Maybe your radiator cap needs replacing, sometimes they go bad and can make the coolant pressure go too high. Or the overflow hose gets clogged and does the same thing.

I've got two radiator caps on my car and if they get mixed up it makes hot coolant spray everywhere.

You haven't noticed any oil in your coolant on the bottom of your radiator caps I hope?

No, def no signs of head gasket issue.

Can you think of something that would actually make one of the hoses to come off the firewall? It's not looking like that was the cause, but rather a symptom. Crazy

I'm gonna pick up a thermostat tomorrow morning, drain the whole system and refill and burp like you're supposed to. Hopefully it's it.
In the overflow reservoir, you can totally tell the waterpump is doing it's thing. And usually from my experience, systems with overflow reservoirs usually will burp themselves quite easily. But again, i even primed the drained heater core and hoses.

Air bubbles can be a real pain in the ass.

For sure!, especially from a drained rad core. But i haven't been able to fix it. Pissing me off.

Yeah, mine is real easy to burp on the subie. I feel for ya, glad that it's not the head.

As far as having the hose pop off, either the pressure in the coolant system got too high or the hose is old and fatigued or the spring clamp is fatigued or it got oil in between the hose and the barb.

These are those quick connect fittings they got on most newer cars. Why it just came off is tripping me out. But yeah, like too much pressure happened? I dunno.
The radiator is only about a year old. The water pump the same. The engine i just replaced about 4 months ago.

Oh hey when those things get old they've got a rep for going bad on their own.

Chirping the tires @60... I had a 750il that sheared the impeller off the shaft, never leaked a drop from the pump.

Chirping the tires at 60yrs old still? Fuck yeah!!!
:-)
As far as i can tell, the pump is working. Gonna score some more 50/50 dexcool tomorrow along with a new thermostat. Might even boil the old one first to see if it opens. There's a chance there's some air still in the system i guess. I'm gonna go through a whole drain and fill and burp and hopefully that fixes it.
