Re: [MBZ] W126 Weird Hose

[Dan Penoff via Mercedes]

True.

I got a “hose mender” kit at FLAPS, but the 3/4” hose barb fitting was too 
small in diameter.  So off to my Ace hardware and there I found a nylon 3/4” 
hose barb that was larger in diameter and fit perfectly.  I as hoping to find a 
brass hose barb but they didn’t have anything that big in brass.  I’m not keen 
about the nylon fitting as I have some concerns about temperature, so I’ll 
leave it in temporarily and go hunting for a 3/4” brass hose barb fitting this 
weekend.

No word on whether or not the hose is still available.  Parts guy says Germany 
shows it’s a good/active number, but the only way to be sure is to order one.  
For now I’m not dropping $90 for a hose I don’t really need.

It’s a weirdly molded hose with a bunch of strange turns in it.  It’s certainly 
possible I could use bulk hose, but I would have to come up with an in-line 
fitting (tee) where the little line comes off to feed the windshield plate 
heater near one end.  I don’t think any of the bends in it are of such a short 
radius that you couldn’t use straight hose, however.

It got compromised because the clamp I used to clamp it off perforated the 
hose. I'm comfortable with the integrity of the hose itself.

I'm going to look for a metal or plastic sleeve for the repair. I'm not 
terribly keen on the silicone tape thing, as a repair like this tends to fail 
again when you least expect it.

Thanks, everyone. It's good to have some folks to bounce these things off of 
for different viewpoints.

Penny wise, pound foolish. Odds of durable patch are pretty much zero. High
chance of failure and overheating engine on freeway with attendant head
issues.

I like the cut and splice metal sleeve in idea. But it cracked for a
reason. I never really mind shelling out cash for oe hoses when needed,
because then I no longer have to think about that hose for a decade or
whatever. I think I destroyed one like that on the 617 at the back of the
head when the head came off; it looked fine but when I pulled on it to
remove, the inside of a bend came apart.. They all got replaced with hoses
from Tom Hanson. When you manilulate it to splice you may crack it again in
another spot, so be careful not to pull too hard on it.

Good point, and something to consider for sure.

As I mentioned in an earlier post, the hose itself is in good condition and 
does not appear likely to fail otherwise.

I think I have a moderate chance of success.  I’ll drain the cooling system a 
little so I don’t have to worry about coolant leaking out while I do the job, 
and I’ll be using a 3M silicone hose product, so no cheap materials in play.

I’ll check to see if the MB hose is NLA or not as a last resort.  Too bad the 
same hose isn’t used on the 300SEL, as I would just rob it off of that car and 
put the patched one on the 300SEL.

I’m picking up some silicone sealing tape tomorrow.  I had clamped off the hose 
yesterday while troubleshooting my ACC system, and I suspect the edge of the 
clamp I used cut into or creased the hose.  The leak is just a tiny spot that’s 
no more than 1/8”.  The hose itself is in good condition, it’s not dried out or 
hardened, so if I can patch it I should be good for a long time.

[MBZ] W126 Weird Hose

[Dan Penoff via Mercedes]

Just found a small crack in a hose that goes from the left rear of the engine 
near the oil filter housing into the “false firewall” and over to the heat 
exchanger connection.  From the looks of the EPC it’s also got a little branch 
that comes off to feed the windshield plate heater.  MB part number 126 832 33 
94.  Can’t tell if it’s NLA, as it shows being available on a number of 
different parts web sites.

Anyone ever change one of these out?  It looks like a real PITA.  I’m seriously 
thinking of trying to patch the hose, as the crack is only about 1/8” and it’s 
in an area where I can get to it pretty easily.

Here’s a link to the EPC picture.  It’s part number 158:
