Their diagnosis was a blown head gasket which would have costed several thousands of dollars. I took it to another reputable mechanic and the diagnostic revealed a stuck thermostat, and no blown head gasket. They checked all the valves which were operating with specifications, no mixing of fluids found, replaced the thermostat, and retested with no pressure failure and consistent engine temperature since. Fluids look good. I am very disappointed with their assessment and will not go back there.
We are sorry that you had a less than satisfactory experience at Tigard SUV and Auto Repair. Anyone can make a mistake but we ran the block test (Checks for combustion gasses in the cooling system) twice with two different technicians as is our policy when it fails. We left a message inviting you to bring the vehicle in so we could run the test in person, but have not received a call back yet. We are puzzled as to how a thermostat could resolve a mechanical failure like this but suspect a lower opening temperature thermostat was installed to bandaid the situation. We stand behind our diagnosis and invite Parker to bring the vehicle in for the test.
