    Hi Mike, You have three choices here and the guys have hit on them. 1. Larger radiator 2. better forced air through the radiator 3. switch back to 50/50 ( Evans is a very good coolant because it has no corrosion problems and a high boil over temp. it does raise your CHT's approximately 25-40F depending again on the radiator set up. water is able to absorb more BTU's from the engine, but it has a lower boiling point. Going back to 50/50 is ok if you can not get the CHT's back down with the other two suggestions, but then you will need to use the lower CHT/water temp) -------- Roger Lee Tucson, Az.

    Hi Jim, You can call the probe mfg and get the specs and use a meter on them or put them in a known hot area (like boiling water at 212F) and check your gage or check them against another known good probe/gage. -------- Roger Lee Tucson, Az.
