Welp. I’m stumped. My coolant is bubbling and puking out the reservoir.
Replaced reservoir thinking it had a leak or bad cap.
Replaced thermostat 2 months ago.
Replaced radiator w thermostat (had small leak)
Not overheating at all, but gets a little warm after it pukes out enough coolant at highway speed.
Good compression on all cylinders. Less than 3 lb variation, cold and warm.
No coolant in oil. No oil in coolant.
No appreciable loss of power.
Owned truck for 6 years and it’s never overheated on my watch.
I’m stumped y’all.
Bubbling stops appx 1 min after shutdown, and it’s nowhere close to hot.
Anyone else had this happen?
