Short Passenger Rear 5.9L Cummins Block Coolant Hose?

**super_kev** · 10-25-2023

Hi folks, it appears I have a coolant leak, and it's coming from the coolant hose wrapped in foil a few inches away from the turbo exhaust; it's pretty short, like 6" or so.

I'm leaving in a few days for a trip, so I'm happy I saw it dripping, but it pisses me off it has to leak now.

1) What's this part called (or part number, 2007 5.9L/48RE) so I can find it online or at my local dealer?
2) Is there a better aftermarket replacement?
3) What does it go to?
4) Does the 6.7L have this same design/problem?

Thanks.

Is it leaking from the rubber part of the hose, or is the metal connection corroded and leaking?

I’m not sure what this part is, but it looks like a short section of heater hose.

Maybe you could go to your local auto parts store, get a foot of hose/ new hose clamps, and cut it to size if it’s just the hose.

If it’s just the hose, replace it with a section of blue silicone hose.

The silicone will hold up better with the high temperature in that area.

Yes, it's the hose.

I didn't think of silicone, but that'd work better than rubber.

Who makes silicone replacements for these?

You must measure the hose ID and call around your local area for a vendor.

@Geno's Garage also sells silicone hoses.
