Noisy Workhorse engine fan
Has anyone else been irritated by the thermostatic clutch fan on 8.1 liter Workhorse chassis being very loud? I would like to lessen the times I hear it. I have NEVER seen the gauge climb past 1/2 way...

I would leave the fan alone, especially since you have no idea what your gauge is telling you. Saying that you want it to come on after the half way point vs before the half way point is not very scientific. Many wish they had you're issue.
I would attack it differently......If you don't have the electric fan(S) add one or two. Many RV's with your engine had an issue with keeping the manifolds and plug wires cool because of poor air flow. You can take something like dryer hose and route it from the grill to both sides of the engine. Lastly, increase your doghouse insulation to drown out the sound. Try and get it up around the firewall where you can.
