The engine runs at approximately 170 degrees at idle (it's 34 degrees in the garage today) down from approximately 180 degrees this summer.
The heater hoses are hot but the radiator hoses are just warm. Sticking my high tech temp sensor (my right forefinger) in the coolant
at the radiator cap I find it's lukewarm. I also don't see any circulation at the top of the radiator.
Is the thermostat stuck?
Thanks

It is opening just enough to maintain the correct heat in the motor. | | | | | Joined: Oct 2019 Posts: 131 'Bolter | | 'Bolter Joined: Oct 2019 Posts: 131 | | | |
