coolent system

i have a 06 lbz and the truck keeps building pressure in the antifreeze reservoir tank and once it builds up enough pressure it boils out the over flow hose. we have changed the thermostats. was told that it could be the water pump or the head gaskets.

After sitting overnight, or several days, is the top rad hose firm? Or can you squeeze it flat with minimal effort?

Is the EGR still intact?

Check the firmness of the radiator hose the next morning after the truck ran. If it is rock hard, that is an indicator of a bad head gasket.

When my water pump was bad, my truck would randomly piss out coolant. I never had any pressure in the tank. But my truck is an lb7, might be different for you.

They're all next to the T-stats, up top. Easy access.
