I messed up and drove at hot level. Now my gems engine has a nasty squeal coming from the engine. It is not the water pump as I disconnected the belt and the squeal is still there. I fear I ruined the engine. It sounds like rubber squeezing in the engine under the valve cover. Any thoughts that maybe the engine could be fixed like something the valves could be fixed. Timing chain? Thanks

 

Very difficult to diagnose any specific injury based on the description of a sound.

- how long was the vehicle run in an overheat condition?
- do you know how high the temperature was during the overheat condition?
- did you lose a significant quantity of coolant?
- have you tested for exhaust gasses in the coolant?

If you think the sound is coming from under the valve cover, pull the valve cover and visually inspect the rockers, springs, and valve stems. Take a picture and post it here.

 

I ran for five min very hot. Coolant leaked out as I thin the thermostat got stuck closed. I think I will tow it to a mechanic.

 

Gotta check your fluid levels.
Where is the coolant leak located?

 

Only thing that I can imagine would "squeal" is a massive vacuum leak if a gasket gave way, even that is a long shot. Good to have a mechanic look it over. Let us know how it goes, please.
