john_harris Report post Posted September 21, 2023 2007 Holiday Rambler Endeavor pusher. Had issues returning from cross country trip with overheating and loss of power. runs fine on level but under load on long grades looses power at 208 degrees. Original diagnosis pointed to clogged radiator and clogged fuel filters after running biodiesel from west coast. Rad cleaned and both fuel filters changed. fuel delivery not issue. All now pointing to bad fan clutch. Local Cummins shop says the can not find replacement as this in not a Cummins part but one supplied from OEM (Monaco) Anyone had similar issues or difficulty in tracking down fan clutch. or potential source for same.

wildebill308 Report post Posted September 22, 2023 Did you try manually down shifting to a lower gear when it got hot? I would ask on the IRV2 Monaco owners forum https://www.irv2.com/forums/f115/ They will probable have more traffic. Have you looked at https://sourcerv.com/ Bill Share this post Link to post Share on other sites
