That’s what I was thinking. The terminals on the coolant sensor are out there to be accessed by any and all comers. Attaching something to the inside or outside of the instrument cluster is heading towards rocket science.

Then I checked the cooling system again with pressure, exhaust fume detection fluid and IR temperature gun. Replaced radiator and water pump. No issues found, although my radiator is now a bit smaller (used to have the 606 one) and city driving in 90-100F ambient results in 85-90C engine temp, which is still perfectly normal. Head measures 92-95C. I wonder if an electric fan instead of visco would quiet it down a bit and keep temps lower, for better AC efficiency. Best would be to keep the aux pump running after engine shut off for another 10min to avoid coolant temp spike. If you run city errands on a hot day, you come back to your car after a few minutes to see the engine temp at 95C and AC totally sucks.

87tdwagen: interesting point about oil catch can. I had it too for a bit. I did lose a quart every 4-5k miles, I had a light white smoke on idle, not much though. I ran LM engine flush for 10min before last oil change and for the past few months, I have zero smoke from exhaust. Did good 2k miles and oil level is approx the same.
You used a 606 radiator? Which car are we talking about? I was under the impression that swapping a different radiator into an SDL was pretty tough. I have one of the Chinese one piece aluminum radiators. Seems like a good unit.

But I always figured that if my SDL radiator went, and I couldn’t find a unit made for the SDL that I would figure out a way to jury rig another radiator, would just need to find one as close as possible.
