Did the boil test last night, the thermostat I just took off the car opened nicely near the boiling point. Fully opened when the water was boiling. Also checked the upper hose again, no pressurized syndrome. So I guess new pump is the next course of action. I still have a Laso pump on hand. Would you all think dealer parts is superior than the OEM parts on this one?
I think the pump you have ready to put in is the superior one, but only because I'm still not convinced that it will make any difference and using it will allow you to conduct the test immediately. You're _sure_ the radiator flows well, the thermostat is in the right way around, and that there's no huge air bubble trapped in the head? -- Jim
