Gents,
I'm afraid I have bad news. I recently purchased my 1965 Mustang 289 4V from Helena Montana and brought it to San Antonio Texas and I cannot get it to stay cool. New radiator, new thermostat, timing and carb adjusted, new radiator hoses all done by seasoned vintage mustang Mechanics at Alamo Classic Ponies, here in San Antonio. They have determined it is not the fault of the cooling system but instead discovered my engine is producing to much friction causing the thermostat to remain in the open position allowing water to constantly flow from the engine to the radiator and back into the engine again before the fluid has had an opportunity to cool down in the radiator.
They now believe it could be the following: 1. The engine may have been overbored to .060 or 2. internal engine components have been scorched due to overheating one to many times.
They are getting me prices on two options:
1. new crate engine (recommending 5.0L 302 engine)
2. pull engine from car and rebuild.
QUESTION: Has anyone else experienced this specific issue dealing with an engine that could not stay cool because of something other than a bad cooling system? If so, what do you recommend?
