The caps came in earlier today, and I installed them this afternoon.
That addressed the leak, but the idle was very high, around 2500 RPM.
I hooked up the ScanGauge, which indicated the coolant was at -27°C (so obviously wrong, as the ambient temperature was around +25°C, and the coolant a bit hotter yet).
I took the coolant-temperature sensor out, cleaned the scale off it with a small file, and reinstalled it. That helped a bit, but not enough, with the ScanGauge then reading -12°C.
I phoned my favourite local parts store. They brought in a new sensor for me, and I was able to pick it up before closing time.
For fun I ohmed out the old part (bouncing around between 400K and 1.5M) and the new part (26K).
Installation was easy.
Idle is smooth at 700 RPM, and the coolant temperature stabilized at a reasonable 96°C (indicated).
I figure the original sensor got cooked when the engine lost its coolant a few days ago.
Anyway, no apparent damage to the engine.
