Chevrolet 1995 Camaro radiator running hot. The overflow shows full? Belts are good and all in place
DO YOU SEE BUBBLES IN THE RADIATOR/ IF SO YOU HAVE A BLOWN HEADGASKET IF NOT REPLACE THE CAP AND SEE OF THE SYSTEM BUILDS PRESSURE IF IT DOES AND THE HEADGASKET IS GOOD REPLACE THE RADIATOR
How do you know it is really hot?
It is boiling over, or just gauge?
Gauge could be bad, use thermometer to verify.
But whenever engine gets too hot, thermostat is always ruined and needs replacement, regardless what caused it and may also be wrong.
Less common cause can be head gasket. In car radiator pressure test can detect that. Pump it up to 17 lb or whatever the cap is rated to, and if if is leaks down. Or run the engine, and see if pressure pulses of goes over cap rating.
Least common is a loose bearing in water pump can cause it to bind.
