I've had my 1990 Venture about 1/2 a year and put about 5000 miles on so far, no major trouble. However, a few days ago I took a 60 mile trip up I-25 to Denver, 95+ degree heat and 85+ mph most of the way. When The interstate traffic slowed considerably I exited and took city streets the last 10-20 miles. The temp gauge was very close to the red zone for most of the city streets, and was just a little cooler when hammering down the highway. After a few hours I left Denver the temps were cooler, I rode a little slower and the temps were normal and cycle run fine. It has 32,000 miles and coolant level is at the full mark. I beleive the engine fan works. Fuel milage that trip was 37mpg.
So, Are these engine temperture extremes normal? Should I be concerned? How do these cycles run in 110 degree weather? (I'll be moving to South CA desert in a few months). Should I look into some service or maintenance work?
later,
Roy
