On my 92 eurovan when I got it had problems with the gauge cluster - namely the rpm the temp and gas gauge. Solved the rpm and gas problem and determined that the temp problem is in the 4 - wire sending unit, as I used a spare that I had and now it works better but not accurately. With the two speed fan running full tilt coming off the highway, and it's been hot and humid - it's only reading about a quarter way up on the gauge. The replacement switch has a different color and part number and has 140 degrees marked on it. The original has 120 degrees marked on it. Doing some research I find that there are a number of different temp switches available with all different part numbers and colors.
Anybody know if the gauge accuracy is determined by the switch??
Thanks.
