Met Ed and Nathan Mayer at McD’s, and east we went: brakes worked well.
On I-480 just past the bridge, the tempgage suddenly shot up! Stopped by the side of the road: no obvous leaks, plugs looked fine.
Ed and Nathan went to get coolant – temp dropped, and then rose. We stopped again, added coolant, let it cool, and then it got hot. Pulled over into a Marathon Station on Warrensville, and exercised our flatbed insurance option.
They arrived, Mini was pushed on, and we headed back home.
Ed came over later:
Pressure test showed no leaks.
So we measured compression: 172,174,178,190 – so no head gasket issue.
We decided to check thermostat, and found it broken.
RCA – stuck thermostat, and perhaps I shall carry a spare.
