I got a Scangauge II this past Xmas and hooked it up. Water temp was maxing out at 190 on the highway and 193 in traffic. Recently, I noticed my water temp rising to 195 on the highway and up to 202 in traffic during 50 degree days. I felt this was a little high and was starting to concern me.
This Weekend, I replaced the water pump, thermostat and belts and performed a radiator flush. Now temp is 182 to 184 on the highway and maxes out at 186 in heavy traffic during 50 degree days.
I took the old thermostat and put it in some boiling water. The most it would open was about 1/16 of an inch. I am positive that my thermostat was failing and I had a flow restriction. If I would have run this in the summer with 90+ degree days, I am positive that I would have some major overheating problems. Thanks to the precise measurement of the Scangauge II, I was able to detect this problem before it became a serious issue.
