M201/Trailer Test Drive - August 27th

Coming home from the Fishburn show, I'd only been driving a little over a mile when I got a brief cloud of steam around my feet. I pulled over and found coolant splashed all over the inside of the hood, sprayed around by the fan. There hadn't been enough lost to empty the radiator, so after a check the engine would turn, I started up and drove home carefully. This is covered in the August 2021 Ongoing Work section of the website. On August 23rd, I did a static engine run to check things over and followed that later with a test drive with just the Jeep and found no problems.
 
 
With another couple of events still to go, I wanted another test pulling the loaded trailer. This was done on August 27th with the action camera mounted on the back of the trailer to give a video with a different perspective. As before, no sign of leaks, no cracks in the engine block, no rough running or coolant level dropping. I think on the Fishburn trip, being a cold and damp day, that perhaps the thermostat stuck closed until the heat and pressure built up, then it popped free and the excess pressure blew through the radiator cap valve. Basically, a Jeep Sneeze! I'll keep en eye on everything, but for now, all seems well.
