motor riving up while driving
I was driving home from camping and noticed that at different times the engine on the coach would sound like it was racing. during these times the rpm on the tach did not change. the temp gauge was in the safe range, and it did not heat up. motor is a big chevy engine and was performing perfectly. my question is, is this normal, a way to help the engine cool. it was a little over 90 degrees that day. i live in Louisiana and the heat is a factor. thanks for any help or information.

Sounds like your fan clutch was doing what it is supposed to do... cool the engine by providing additional cooling air across the radiator.

What you were hearing was probsbly the cooling fan cyclingmon and off. Normal as long as temps remain steady.

Fan clutch engaging maybe ? When the fan runs it makes quite a bit of noise. Running down the hi way ram air is usually sufficient and the fan just barely turns, however on hot days it may cycle on and off.

You most likely have a clutch fan assembly on the motor. The clutch fan is not affected by the engine coolant or thermostat directly it by the temp of the air flowing through the radiator. I'm guessing that the clutch fan is engaging in the high ambient temps and causing the increased noise level.

Not that I do disagree, but just to be contrary, I would disagree.  Then I would not only be contrary, I would also be wrong.
