2000 Nissian Xterra Overheating

[erayh]

I have a 2000 Xterra that has started overheating. I've replaced the thermostat, water pump, and head gaskets. It still gets hot and starts blowing water out of the overflow. I'm out of ideals, and need a fresh look on the problem, any help would be greatly appreciated.

try replacing ur radiator cap to a higher psi rating. ur cap may be bad.

tried that today and also completely flushed the radiator and lines. It did have a effect it took 20 min. to start overheating instead of 10. Thanks for the input.

u could try reverse flushing the radiator system. u need an air pressure gun but that would literally clean out all or most of any deposits that have built up.

dirty oil and sludge could cause ur problem. replacing it would do the trick.

check for any obstructions within the fan shroud. this would prevent air from flowing through the radiator.

or it could just be the radiator itself. replacing it would be ur best bet if none of these options work.

question. whats ur mixture ratio of antifreeze to water?
