Got up early this am to prep for Solon Show – 37th annual.
Met Ed and Nathan Mayer at a local McD’s, and east from Avon Lake to Solon we went
Things were moving well, and the brake adjustment from Saturday seemed to be working well.
On I-480 just past the bridge, the tempgage suddenly shot up! Stopped by the side of the road: no obvious 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 when we started back up, it got hot. Pulled over into a Marathon Station on Warrensville, and exercised our flatbed insurance option from Haggerty
They arrived, we pushed Mini on, and we headed back home.
Pressure test showed no cooling system leaks, so we measured compression: 172,174,178,190 – so no head gasket issue. We decided to check thermostat, and found it broken.
