Question about 1997 Chevrolet Tahoe
My 96 Chevy Tahoe is over heating. I have changed the water pump, thermostat, hoses, flushed the system, added coolant and even changed the radiator, and its still over heating. I can't seem to figure out what else it could be. Can anyone help? Is there something I am missing? PLEASE HELP..
After your exhaustive tasks I feel one of two things are left to rule out.
First, have you an air lock? did you bleed the cooling system after installation of parts? if not try parking on level ground, with engine cold not running remove coolant filler cap and top up if required to correct level.
Start the vehicle and leave to idle with cap off, have plenty of hot water available, when at operating temperature you may here gurgling and see bubbles in the cooling system Beware not to get too close as it will hopefully boil over, after it does top up with warm water and wait, keep blower on full and heat to max inside vehicle.
It may boil/bubble over a few times before settling if so top up and replace cap once settled.
Finally if an abundant amount of air bubbles are continually visible and regular bubbling over then unfortunately the cylinder head or gasket could be at fault.
I hope this points you in the correct area.
Please remember to politely rate this possible remedy!
