Good advice.
I did replace the water pump, thermostat, thermostat gasket, both bypass hoses with new parts.
(As well as reseal the oil pump and cam seals and cam caps.)
If I did not replace the upper and lower hoses then they seemed to be in good shape.
When I checked the radiator cap it held 0 psi.
We replaced the rad cap just before you left with a brand new one.
The power steering pump that was leaking at the cap continued to leak for a week after you left, which tells me that the fluid is being pumped out by the rack.
As of our last conversation reguarding the overheating, and water temperature spikes...
I wonder if the old rad cap, not being resistant to pressure, allowed head gasket leaks to pass into the atmosphere, past the original cap, while a good cap traps the escaping pressures, allowing an air pocket?
