mystery overheating

[Alex3000gt]

Remember, when you are on the gas you are generating more horsepower... This means more waste energy (heat) is being dumped into the coolant. Ideally, coolant flow and airflow also increase as you accelerate. Seems you have an issue with one of the two.

1) Try running with no thermostat, if it still overheats that rules out a thermostat issue.

Report back and we can go from there.

that was my next step. ill have to do it tmw. i have school tmw an got homework.

pulled tstat, noticed the gasket wasnt in the best of shape, wasnt leaking but maybe air was getting into the system.

either way i cleaned up the housing, made a real nice sealant around it, an left the tstat out. drove in town without overheating, an drove on the interstate without overheating, i hope i dont regret saying this but i think its good to go

thanks to everyone for help

Awesome. Sounds like your thermostat was failing partially open. Definitely get a new one in ther soon, but in the mean time... ENJOY!

Always happy to help a 3/Ser.

I solved it, my credit!

We can debate this at the NG.

do you really need a tstat?? ive ran cars without them before

A car can overheat without a Tstat. Of course you need one.

Coolant gets cooled in the radiator until the thermostat allows another stream of coolant inside the radiator. Constant flow in the radiator doesn't have a good cooling effect.

gotttcha, thanks

Also your engine takes longer to warm up without a thermostat. This increases engine wear and decreases fuel economy.
