I searched hi and lo for this issue and could not find a thread with a squeak!

2020 DutchStar 3709 with side radiator w/ 8000 miles

Noticed a Squeak coming from the engine compartment. The squeak was synchronized with the rotation of the drive pulley on the coolant fan driveshaft. The squeak goes away after it warms up.

Has anybody had this issue? Should I be concerned?

Thanks any help would be appreciated.

Spray some belt dressing on the belt and see if the squeak goes away.

Loose bolt.

I don't have a Newmar, but I do have a Tiffin with the side radiator. Does it have a grear box & universal joint drive shaft to the fan? If so, I would check those 2 items out.

And don't use belt dressing. Every mechanic afterward will hate you. It makes a mess. If it is lose, tighten it. If it is worn, replace it.

A squirt of belt dressing or liquid soap only to narrow down where the squeak is coming from. If it effects or stops it then you address why.

Try the belt dressing first. If that doesn't help, grease the two zerk fittings. They may have been left dry. It can be almost impossible to reach those fittings, so I made this tool, and I can reach them from underneath.
