Hi everyone, I have a 2003 Mustang Cobra that intermittantly overheats and blows coolant out of bottle. I changed the thermostat and filled coolant with bleeder out and it was fine for about 150 miles than it overheated again. Can't find any leaks car runs like a top. Any suggestions? Anyone ever see this with their car?

 

Is your electric fan coming on at all? The motor might have died / popped a fuse / short ...etc...

 

+1 that. It happened to me when i was working for my girlfriends dad who owns a body shop. We were cleaning up a dodge turdbox caliber, and it kept over heating. So we checked the fuse and it was blown. bought a new one, and fixed it.

 

FAN WORKS COMES ON @ 210deg

 

make sure you aren't just dumping coolant in there, is needs to be 50/50 with water.

 

also make sure your letting the coolant bubble and let all the air out...because if trapped air is in there it will overheat..
