Spare hoses for MB breakdowns - or Silweld ?

Post by drcdb15 » Sun Aug 26, 2018 10:38 am

One obvious conclusion from the search earlier this year for silicone hoses for the MB is that there aren't any. Well, not in your friendly neighbourhood Halfords anyway. Nor it seems are ordinary rubber hoses to be found on every high street. So it occurs to me, it might not be a bad idea to carry a spare hose or two in the car, so that if something nasty happens and you need to call out a repair truck at least you can offer more by way of parts than a roll of gaffer tape and a jubilee clip.

So the question is, which hose(s)on the MB are the most critical, and or, likely to fail on a cold wet November night over Shap? Or is it so unpredictable that a roll of (Silweld?) tape actually makes more sense? Thanks for your thoughts.

Hose repair tape, I’d say. Possibly a small length of a large size you could use as a patch/splint in case of an impressive split?

The one you are not carrying a spare for!

The most difficult one is the waterpump hose, It is an awkward shape and NLA as a Motorcraft part. If it has not been replaced recently check it and have a spare available.

Hose tape would be a good alternative but any time I have had a problem it tends to be a split around the clip which can be sortable if the hose can be shortened. The heater hose is a different diameter at each end and I have replaced mine with silicone and a reducer piece to join the two. Some replacement hoses for the radiator are bellows type which could be difficult to repair well with hose tape.

The stand by is to always carry a "get out of jail free card" in the form of roadside recovery!

Can you be more specific, please, Will - which item is this on the parts list? There seem to be several labelled 'water pump'. Also I don't see anything named this on QRG's spares list. Thanks.

Hose number 2 on this diagram, the bypass hose QRG had a number made in Silicone. Don't know whether they have any left but they were advertised on Mick's site. Here

Thanks for that Will, and apologies for not replying sooner, but I've had trouble identifying which hose this is on my car. Is it this one:

012.JPG

?

I spoke with QRG today and they are listing a bypass hose for the MB at only £25.20 - Nigel wasn't there to confirm but I was told it was probably silicone, as "we are doing more and more in silicone these days". Either that or they've discovered a secret hoard of NOS, because my extensive internet searching for the Ford and Motorcraft part numbers has yielded precisely nothing. How is it that Ford produced this engine in pretty substantial numbers yet stocks of this hose alone seem to have been all used up? Is it really so much more prone to failure?

Anyway, my roll of Silweld tape arrived today, so what can possibly go wrong?

Have you expanded your search to include overseas sources, ie the American vehicles that use the Cologne? I think they share lots of parts.

I have a feeling Ford (US) use a different set of part numbers - as Jim says, see if the same (looking) hose is used on, say, the Ford Explorer or (I think) Mustang with the 4.0 OHV?

The Granada was called the Scorpio in Europe and of course the engine was found in the Sierra and transit as well as specials like the TVR and Panther Kallista, but I’d imagine they’d show up in a FoMoCo part number search?

Yes, been there, got the tee shirt etc :lol: A couple of years ago, as Will alluded to, Nigel at QRG got a remanufactured batch in silicone because this hose was unobtainable, and it seems it still is!

Oh yes, they show up in parts lists. What they *don't* show up on is in suppliers' "yes, we've got it in stock" lists :cry:

But back to my photos above, am I looking at the hose in question ?

Yes, that's the one in question.

Like you I have searched and not had much luck finding a supply other than QRG which is, as Jim says, surprising given how many of these engines were produced and must still be in use. The one I replaced on MB14 was NOS bought from eBay so they do turn up from time to time.

So, if I understand it correctly, QRG had them remanufactured - so the template is there, you just need Nigel to place an order?

QRG told me today they have them in stock, and as I mentioned above, it is presumed these are from their original re-manufactured batch - Nigel himself wasn't in today, and the chap I spoke to wasn't too sure of the details. When I said (above) the hose is 'unobtainable', I meant stocks of the original OEM or pattern are unobtainable, apart from the occasional NOS that comes to light, as Will mentioned. QRG would seem to have a global monpoly on them !!

As to whether "the template is there" or not, well, I couldn't say. I'm sure if Nigel got the mandrel he will still have it, but from what I could gather in my searches for a complete MB silicone hose set earlier this year it seems the firms that make silicone hoses have a - shall we say - less than rigorous approach to tooling. They seem to cannibalise bits of mandrel as and when it's expedient to fulfil the orders they have to hand on the day. Having said that, they seem as well able to make a hose from a sample as from a mandrel, so if QRG (or anyone else) has a good unused sample that in itself should be enough for any hose maker to remanufacture.
