Gentlemen,
I just road tested my GMC. It had sat for 30 years and had 8,000 original miles. The engine is running great, but hot. The analogue guage indicated 225 degrees and steady. Up hill and down, all the way to 60 MPH and coasting. The Digi panel reports High engine temp, alarm and red emer. light.
The coach has a new 195 degree thermostat, new water pump, re-cored radiator and all new lines and hoses. I spun the fan clutch and got less than 1/2 rotation. Dash temp guage indicates first 1/4.
Do you guys think this is a result of running in a 45 year old engine with low milage? Maybe surface friction from an old stored engine or perhaps something else?
Thanks in advance for any tips.
Take care,
Tom K
