Well the Sputinik (or similar) is probably where I am going next. I got a new Sunpro electric guage and hooked it up this week. Assuming the gauge is correct, between 1/4 and 1/3 travel on the OEM gauge is 200o .Taking the car around the neighborhood for a 20min spirited drive, my temps were this and were still inching up. The problem is not with my OEM gauge and now I know where the needle should be.
