2003 buick century overheating issues
I have a 2003 Buick Century and i have replaced
the temp sensor and the thermostat and i am still
having overheating issues. When i opened the
radiator cap there is gray sludge on it. I wanted to
replace the radiator and the water pump along with
the gaskets and hoses (of course). I dont want to
spend unnecessary money if it wont fix the
problem. Does anyone have any suggestions?
The sludge is probably engine oil or transmission fluid. If engine oil, you have a blown head gasket or another defect in the engine. If trans fluid, it's probably leaking from a rotted out trans cooler. Fix this before you try anything else; the price to fix might exceed the value of the car.
