ok, first, did you replace the head gaskets???

did you at least do a leak down test on the cylinders to confirm the gaskets are good??

the excessive pressure could be coming from a leaking head gasket leaking compression into the cooling system

My worry is water pump but what a bad water pump cause that much pressure
Customer reply replied 1 year ago
a slight grind noise coming from pump
Chevy Mechanic: Roy, import/domestic specialest replied 1 year ago

ok, I understand but you still may have a gasket issue. as I stated, the only way to confirm is a leak down test to confirm.

I will opt out of this and see if someone else can help you.

Would a bad water pump cause pressure in the lower and upper radiators hoes and cause engine to over heat
Chevy Mechanic: GM Bob, ASE Certified Technician replied 1 year ago

Yes If its not working properly.

Pressure builds up from overheating. If it builds up cold startup may have a bad head gasket?

You don't think you have a air pocket?

If the pump is noisy may have a internal problem.

Was the pump replaced?

Pumps going to be next
Chevy Mechanic: GM Bob, ASE Certified Technician replied 1 year ago

When it overheats are you driving or idling?

If the radiator or fan is not cooling properly the pressure will build up.

You antifreeze in it not just water?
