There are quite a few ways to evaluate damage as a result of an overheating issue.
1. Cylinder Compression tests will most likely reveal a problem, low compression = a leak in either the head gasket, valve seals, or piston rings.
2. White smoke from the exhaust is a sign that coolant is entering into the combustion chambers and burning which is a result of a blown head gasket or intake manifold gasket depending on the application.
3. If coolant blows out the top of an open radiator inlet when the throttle is pressed in most cases that is a sign that the engine is sucking air into the cooling system which could be through the head gasket or intake gasket depending on the application.
yeah. It happens
To keep the car engine from over heating
Many things can go wrong with a car radiator. Since the car radiators job is to keep the car from over heating, the radiator can become to hot and become damaged, and it can also become clogged with dirt and debris. A car radiator can also become rusted and sludge can get built up in the wires which will cause it to over heat.
your car is over heating
If it is not actually over heating, then if the smell is outside the car, look for coolant leaks around the head and the thermostat cover. Inside the car could be a leaking heater coil.
If your car is over heating you may want to check your thermostat and replace it may solve your over heating problems
over heat could be several reason radiator chokeup, less coolant, and also could be your compression leakage through cylinder head gasket
that's because car was on too long. that's because car was on too long.
If the car is over heating or if a sound that shouldn't be there can be heard due to worn out pump bearings.
Can result in freezing in the winter and over-heating in the summer.
If your Pathfinder is over heating then you may have an issue with the coolant. You can try adding more coolant to ensure that your car is no longer over heating. You can also double check to make sure your blower is actually cooling your engine.
I'd like to know this too!!
