Serpentine belt
Have a question on how long is a reasonable time to replace the Serpentine belt on a Cat C-7 engine. It's been 28,000 miles since it was last replaced. Had one break and had a bill of $1,999.00 becaus...
Forum Discussion
Where do ou have it installed and at what labor costs?

Because of the higher heat where the belts are located in a diesel pusher, I would strongly suggest 10 years is twice what I would run.
And very likely on the Caterpillar C7 you have a separate V belt that drives only the water pump. It is NOT on an automatic tensioner, so tension needs to be checked and adjusted occasionally. And, replace this belt when you replace the serpentine belt.
EXACTLY!!!!!!!!!!
We've owned our '04 Itasca Horizon 36GD with the CAT C-7 330HP now for 8 years and have put 42,000 on it since we purchased it. And I've changed that Serpentine belt and the water pump belt TWICE in that time frame. Those belts are waaaaaaaaaaaaaaaaaaaaaaaaaaaaay too cheap to try and stretch a life span on them especially since we often are on looooooong stretches of baron roads and freeways. So, knowing I've done at least that to help preserve our nice travels, is a great piece of mind.
