I have a 87 190 and my temp seems to be dead on. The only catch is it's in C and I am in the US and used to F. Any idea how to change it? I am tired of having to add 32 and divide by 10, take the square root of 5, add the weight of the sun, less the weight of the moon and divide by 2 to get the temp.

Anyway, O would like an easy fix for this as everything else on this god forsaken car has cost me an arm and a leg to repair. If it is too involved I will have to live with knowing when it says 40 its too damn hot, 0 means it's a tad nippy out and when it is reading 20 it's just right.
