Coolant hoses looking rotted, need help finding replacements.

[Eddie5499]

Hi everyone. I've recently bought, insured, and registered my bus, but it needs some repairs before we can really get it on the road, which I'm hoping to do within a month. Among such repairs are replacing the coolant hoses, but I'm having trouble finding the proper replacements online. If anyone could offer any advice on finding good replacements, let me know!


If it helps at all, our bus is a 2009 Freightliner Thomas C2 with a Cummins ISB 6.7 diesel engine.

Try tacbusparts.com Another idea is to go to your local school bus agency and ask them who in your town helps them get parts.

I'm not sure they have what I'm looking for but that site could come in handy in the future anyway. I might look into your other suggestion too.


I'm looking to replace the rubber coolant hoses connecting the pipes, not the actual pipes. I don't know if I need to find specific ones or if I can just use any generic ones I find on amazon or whatever, though at this point I'm thinking I'll just try my luck with whatever is the right width because its just a hose.

Im replacing all my 1in hose with the below. I'll get the short runs of 5/8 or 3/4 locally.

Although can anyone chime in if this is as good as the Goodyear brand I'm replacing? I couldn't find Goodyear anymore.

If you go to a parts house that deals with large trucks you will stand a better chance. Autozone won't be your friend there. Carquest and NAPA will be a better choice.

I think I need bigger than 1in, you can see in the pic of one of them here. But I think you're on the right track, I just need to find the right size.

Be sure to check that steel pipe real good while you are at it. It looks like salt worms have been chewing on it. The hose is gates green stripe comes in many sizes. Comes in 3 foot sticks. Some parts houses will cut it to length for you. Just check the inside for dry rot from sitting on the shelf. The inside goes before the outside from shelf storage.

Some years back I experienced a heater hose failure on the "old Crown" and got replacement hose at NAPA. Crowns use brass elbows and such in the cooling system. I believe they were actually Gates hoses. One can get them in different sizes.

Will do! Thanks for the help.

If you only need straight pieces of hose, it's better to use silicone hose. It will last almost indefinitely and is more heat-tolerant, but it's best to use stainless constant-tension clamps on it instead of the cheapo generic worm-drive clamps that sometimes cause seepage in cold weather. When I replaced my entire cooling system a few years ago I replaced all my short connecting pieces of hose with silicone, so now I'll never need to replace them ever again.

We just replaced every hose we had the option of replacing with silicone, with silicone. Hard second on the constant-tension clamps. Cheaper worm-drive clamps not only allow seepage but also easily cut through the softer silicone. Clamps need to have a smooth band covering the entire interior circumference. As silicone hoses are much more susceptible to damage from anything that could cut them, you gotta be real careful with routing and use protective coverings (hose loom) anywhere contact could possibly be made with something that could damage it.

re -- your portrait

For your 2009, I am curiously surprised your hoses are not silicone.
Replace that rubber rubbish with silicone.
They will probably out-last you, your offspring, the memory of Nero, and la cucarachas.
