Taking advantage of the 50° weather this afternoon, I jockeyed the cars in the driveway around so that the Slattern is at the top—now that the snow has melted, it’s back to the commuting vehicle. While I had everything out, I pulled the Scout across the street, let her warm up a bit, and then took a lap around the block. As I got about halfway home, the temp needle suddenly woke up and pinged to the middle of the gauge, climbing steadily. I hightailed it home and got parked before it had any chance of going further. Inspecting the engine after shutting it down, I noted coolant spitting out of the radiator side of the top hose, meaning I hadn’t tightened that off enough. The top of the radiator was cool to the touch, as was the cap, which leads me to believe the radiator itself is blocked with gunk. Which means I’ll have to buy some flush solution, drain the whole thing, and see if I can’t clean it out myself.
