Dave;

I'd verify the accuracy of the indicating system, before actually suspecting Cooling Sys...by pulling the Sender and putting it into a bath of known temp (including a chassis connection for a single wire Sender!), and seeing what the gauge does with Ign ON. If gauge is still wacky, check your VStab..Gauge reading high is a symptom of VStab not cycling. See: https://www.sw-em.com/voltage_stabilizer.htm#140_VStab_Info

Good Hunting!
