PUKING COOLANT 7.3 HELP

[Stroked]

hey, drove maybe 10 miles, didnt even barely make it to operating temperature, and got out and there was coolant puking out of the reservoir, and pretty much all of it came out, never overheated, lemme know what you think, oh and all gauges read normal, no funny noises, or different things happening

sounds bad to me not hot and spewin from the bottle sound like a bad head

you blew a head gasket probably. pull the heads off and check them against a straight edge there will be a slight bow but not much. haynes manual will tell ya to pull the engine but i didn't so its possible to leave the engine in.

headgaskets are extremely extremely rare on the 7.3 i think its more likely youll find your problem within the head itself

negative, and youve done something if you blow a headgasket on a 7.3, it was a bad thermostat

[special_ed1977]

true but it kinda depends on how it is driven or its use my empty truck and trailer weighs 16,870 lbs and i did it to mine pulling 21,000 on it up a steep bridge. i checked the head to make sure and then changed the gasket when i seen it was normal. that did the trick for me. i think it happen when it down shifted. ibelieve its like dropping the weight and jerking back on it while its on its way down. multiplying effort or engine load momentarily before the waste gate can react.
