Coolant hoses

[DRBARBER001]

How long does one go on with the original rad. Hoses on a cat c-7 d pusher ?

I believe I was told by cummings 7 years. The best thing to do (although it can get messy) is check at least yearly for worn are soft spots.

Hi DRBARBER001,
Welcome to iRV2. It depends on when the coolant change is required. To be efficient it would be best to do both at the same time. I check my hoses/clamps during annual maintenance. My next coolant change will be when the coach is 10-11 years old. I will change the rubber parts at that time.

I keep several spare hoses in case there is a problem. My Cummins setup has only the really short (8" hoses) connecting the solid piping.

On an 04, I'd think you are doing something that doesn't need to be done for another half decade.

I change mine every other time I do the coolant maintenance.

Don't know Cat's recommendations, but Gates has this info on belts and hoses. They recommend 4 years for coolant hoses.
