Running With Schneider!

My heater hose busted in the exact same way about three weeks ago. I was climbing the Grapevine at the time!

 

I'll have to keep any eye on that on mine... that setup looks like its just designed for a road side failure where you have no option but to call for service lol.

I can't tell if that is insulation or a metal hard line below the rubber hose, if it is a hard line, maybe keeping a few feet of hose and some regular hose clamps could get things sealed up in a pinch?

Never seen a hose clamp setup like that before, almost looks like heat shrink? Weird.

Glad to hear you're back up and running though.

 

Road service guy that fixed mine said he had been repairing this problem a lot. And SNI emergency maintenance told me the same thing!

 

is problem only with 2013's?

 

Good info, I may use this info for my own use. paccar telling me where to and how to .repair is driving me nuts. I also think insurance seemed high as well.

 

FYI those clamps are factory. Just look at your engine you'll see them on all the hoses. Also not a bad design. It's like that for a reason.

 

In this application heater hose is a poor design choice, especially such a short piece. Ever worked on an older vehicle and tried to remove a piece of heater hose? Wiggle it around too much and it'll just snap right off like it was a hard line. All the heating and cooling eventually makes it form to its "position" and any excessive movement will crack it. A really short piece like this is even more prone to it because all of the stress from movement and vibration is concentrated into the small area.

 

Still not a bad design. How would you engineer it? All sold line? Look at that line you have the heater core then concting rubber line long hard line to engine firewall oh wait another short rubber hose then more hard line. Every thing ages every thing breaks just matter of time. Don't like those high pressure lines go fancy put some silicone hoses on it. The silicone hoses last longer and longer better.
