225 running a bit warm!!!

Btw.....we have had many cars come into the shop with the complaint of "running a bit warm". When checked with a Ratech gun some of them the gauges were faulty and reading high.

How are you reading "a bit warm"? Have you checked it with another device? If with a dash mounted gauge; could it be faulty? Maybe too much resistance in the wire?

Just more to think about.
