Cat 330 Engine Overheating
Started having overheating problems en route to Colorado Springs from my home in SW Oklahoma. Looked like a stuck thermostat. Engine would function fine for miles, then suddenly start to overheat. ...

Cleaned the radiator thoroughly, still having a bit of a problem. Seems to progressively heat up. I was in 6th gear, RPM around 1600, speed 62mph more or less. Finally downshifted to 5th, same speed, kept RPM at 2000/2100, engine cooled down to where it should be. Don't understand why this just started. I've put 25,000 miles on this coach in 6th gear, 1600 RPM, no problem. Should I accept 5th gear as a way of life,or look for another solution?
