Title: Suitable Replacement For NLA Right Side Heater Hose Through Firewall Grommet?
Post by: Squiggle Dog on 16 May 2018, 12:34 PM
I'm finding many parts for the W116 are no longer available. Is there a suitable replacement for the firewall grommet part number 1169970481 at the right side heater hose coming from heater core outlet to the servo/return pipe?

The firewall hole is 42mm, the heater hose is about 23mm, and the inner grommet hole needs to point downward. This grommet looks identical to the one on each side where the heater core pipes come through the inner firewall (1169970081), except those fit a 38mm hole and have an 18mm opening in the center. Perhaps a new one would expand enough to fit, but I am skeptical, plus it may be more prone to cracking due to the tension.

I found part number 1079971581. Mbclassics.de says it fits a 42mm hole and has an 11mm hole in the center. Its intended purpose is with a fuel injection wire loom. But, it appears that it will work if I cut off some of the sections. https://www.mbclassics.de/Gummituelle-42-11-45-107-116 (https://www.mbclassics.de/Gummituelle-42-11-45-107-116)
(https://www.mbclassics.de/media/image/product/6330/lg/gummituelle-42-11-45-107-116.jpg)

To make things complicated, Theslshop.com says that it fits a 25mm hole and has an 18mm center hole. I highly suspect that this is an error as the proportions don't add up. The center hole would not look so tiny as 18mm is 3/4 as large as 25mm. https://www.theslshop.com/mercedes-benz-107-sl-slc-fuel-injection-loom-angled-grommet-18-25mm-pre-09-85-1079971581.html (https://www.theslshop.com/mercedes-benz-107-sl-slc-fuel-injection-loom-angled-grommet-18-25mm-pre-09-85-1079971581.html)

Ckamila has a heater case thread and I think he mentioned using a 113 part number and making the inner hole larger to fit? https://forum.w116.org/mechanicals/acc-overhaul-heater-box-evaporator-removal/ (https://forum.w116.org/mechanicals/acc-overhaul-heater-box-evaporator-removal/)

Tough luck SD, I'm afraid. These were NLA at MB for at least 3-4 years now. I haven't found a suitable replacement, but that 107 part you've posted looks promising!

Also NLA is A1169970081, which sits nearby. I have an unverified/unprinted 3D model made for it.  If anyone's stuck you can grab it from my Fusion 360 account: https://a360.co/2Kx9rTs.
I'm replicating rubber stuff from my parts stash in 3D, but it takes countless hours to get right, so progress is rather glacial.

I think I found a suitable replacement! Part number 1169971381 is a wire harness grommet going through the fuse box. It fits a 42mm hole, has a somewhat downward angle, has about 16mm opening (which can be cut back to better fit the 23mm hose), and doesn't have seams like the 107 part number I had considered.

I wonder what The Mercedes-Benz Classic Center does when it's restoring cars for clients and can't come up with the grommets? I guess they just reuse the old grommets even if they're cracked.

Here's another NLA part; 1169961681. It's the firewall grommet with the vacuum lines running through it. Mine's in fairly good condition, but a bit dry and has some small splits at the lines.
(https://lh3.googleusercontent.com/EbMG8R5SGTcl70L7OS4v_bIXb1RTXaXcj3Q1645B-ioNSgsjnqWfulL001e5NEis2-BsR84lbcEcG2T0d8v4EE2YyHo8TmEf7qkYloPHvqf97RQ6fIfVGnLZMKcLsZLs_PHwGb2PqvsxrKp_9txp_TaTLE80-gkXVLNyEpFY5ONsrunZDIQofvhkVZ_D4GP-7E_nEZoRqKKGS3x25Fkv5XYh5rrGKHCNyzzAzAtwOEmCdHhpMDX757x5C8YKw89WOw_GtAlPkU9QP45dY50YLpnuv58UoF-Gpe5FJW24Lk3U0HFFDFCFaLOl8EfYhfiRybUXrYGUk9P7RqLShXDq-6wHApgsg8sLIpONAQiU24N5R8pNhp9ypy1LHCe9SQGKbPaHtT39p79rZCcB1lK69__c_zz5Z3TM8N5RJOLN4fDtkwL4G9kG3-mn6icM8WeWZonKUbY7J9nse24lSdKiy1KZbj-vlD6jQtyEyu9KMMhShKGJYJaa5K4cWRAcYrLG1ERYxW4m9acgxhk02ZTRZvPKS-2ESv9nJL3utcLp-vX0zpPRZRZ1o_ThdTa256MXV3IqvnkWB3hqh3OCb8uoz_VyprK2Wp0enVw40Lg=w1024-h749-no)

The closest match I could find was from a W107 (part number 0089971781), but I have a feeling it would be much too small and doesn't have as large of a lip on it.

But, Palm Beach Classics states it was used on the W116... maybe it's worth trying. Worst case scenario, I guess I'll add sealant to my old grommet.

Ptashek, I wish you luck in your quest to reproduce these grommets. So many of these are odd shapes that you can't just buy from a restoration supplier.

Nathan, were you able to obtain part number 1169970481?

They have their own exclusive parts stash, or make small re-manufacturing runs if the car justifies the expense. This is why some NLA parts re-appear and disappear just as quick from the catalogue.

Ugh... I placed an order with Mercedes and nine items are no longer available, which include:

1. 1169970081 Seals around the cowl drains at firewall
2. 1165013682 Lower radiator hose (seriously?)
3. 1169971481 Grommet for auxiliary fuse box wiring at main fuse box
4. 1169971081 Grommet for wiper motor wire harness
5. 1078210097 Vacuum line ducting at front doors
6. 1169972281 Grommet for control into heater case
7. 1168350098 Foam at top lip of blower motor case
8. 1169971381 Grommet for main wire harness at fuse box, could double as heater core exit hose firewall grommet
9. 1165001275 Hose between bottom of coolant expansion tank and bottom of radiator

I guess I'll have to go aftermarket on the lower radiator hose and use the hose at the bottom of the expansion tank a little longer. It seems these grommets aren't happening, so I suppose the course of action left is to smear sealant all over them. It's too bad the W116 didn't use simpler, generic hose and grommet shapes with greater interchangeability between chassis types.

I've spent all day trying to find suitable alternatives for the parts that aren't available, but at this point in history it seems we must resort to wire and duct tape to keep our cars on the road as parts availability is failing. Even aftermarket parts availability is scarce. It makes me worry for the future of having this car as my only transportation.

They have their own exclusive parts stash, or make small re-manufacturing runs if the car justifies the expense. This is why some NLA parts re-appear and disappear just as quick from the catalogue.

That doesn't surprise me. I say we grab our torches and pitchforks and plunder their booty!

I was curious as to whether the W123 and W126 diesels use a lower radiator hose compatible with the W116 diesel; if so, I was going to order a genuine Mercedes W123 lower radiator hose. The W116 is a different part number and seems to be longer. I picked up a Gates 20700 hose from O'Reilly, which they say fits my cars and many others, including W123 and W126, Ford Pinto, Mercury, Fiat, etc.. It seems close enough to work (and no need to cut it--though W123 owners have reported needing to cut theirs to fit).

The hose is going to have to conform a bit, but hopefully it works, because the options are either it or URO. Actually, AutoZone has a Dayco brand C70705 which interchanges with the Gates hose, so that's another option, though the shape and dimensions are likely no closer to the shape of the W116 hose than the Gates version.

The hose's inner diameter looks smaller than the original, but hopefully it stretches.

I haven't fit the hose on the car yet because I haven't drained the cooling system. The hose I used for reference is a spare. Even though you can't really tell from the pictures, the rubber on the old spare hose is hard and cracking.

I think Gates hoses are supposed to be made in the USA, correct? This one says "MADE IN" and then the country of origin is rubbed off. Hopefully they aren't making them in China or something. If so, I probably would have been better off just buying the URO hose that actually fits.

When I was involved in restoring Mercedes a few years ago, we used to source alternatives to any NLA W113 (Pagoda) grommets from these guys:


They're not bad quality, and they're mostly cheap enough to order speculatively, to see if they might be a fit for a W116 application. The chart at the top of [size=78%]the webpage allows you to search for grommets with specific internal & external diameters.[/size]

I think one of the former MB of Poole (UK) classic guys has good contacts with SLS.
If you find something of interest SD, I can try reaching out to him directly via the MB Club UK with possible questions.

Post by: Squiggle Dog on 19 May 2018, 11:36 PM
I've been (attempting) ordering parts from a couple online Mercedes parts dealerships because the 30% off MSRP which they offer sure beats getting 15% off parts ordering from The Classic Center. I think that their databases are screwy, though. For example, I ordered the hose that goes from the bottom of the coolant expansion tank to the bottom of the radiator (part number 1165001275), and they said it's been replaced by part number 1265001549, which is a coolant expansion tank. How does that happen?

I ordered a short 180 degree heater hose (part number 1168313394) and noticed it wasn't on my order, but another hose I had ordered, which was a long, mostly straight hose (part number 1168310994) was on there twice. I asked about this and they said part number 1168313394 was superseded by 1168310994. How can this be? They are totally different lengths and shapes and are absolutely not interchangeable.

Not only are a lot of parts no longer available, but many parts seem to be superseded by incompatible part numbers. I'm worried if what I'm getting is even going to be correct. This same dealership showed that the rubber boot for the drier pressure switch was discontinued, but another dealership showed it as available, but later came back and said it had to be ordered from Germany. As long as I can actually get the part, and it's correct, I don't mind waiting an additional 7-10 days.

I'll probably contact The Classic Center and see if they can be of any assistance. I often wonder if some of these online parts dealerships fully know what they're doing as these part numbers which they say supersede the ones I need seem totally wrong.

Also, I'll be browsing through the SLS website and seeing if I can find some suitable grommets to replace the ones that are no longer available from Mercedes.

The Classic Center informed me that GenuineMercedesParts.com is incorrect that part number 1168310994 (long, mostly straight heater hose) replaces 1168313394 (short 180 degree heater hose), and that 1168313394 hose is still available. GenuineMercedesParts.com is also incorrect in part number 1265001549 (expansion tank) replacing 1165001275 (expansion tank return hose), but unfortunately, the 1165001275 expansion tank return hose is unavailable. It's worth the effort to be vigilant and double check everything! They confirmed that the following parts are no longer available:

1. 1169970081 X2 Cowl drain grommets
2. 1165013682 Lower radiator hose
3. 1169971481 Auxiliary fuse box grommet
4. 1169971081 Wiper motor firewall grommet
5. 1078210097 X2 Vacuum line ducts for front doors
6. 1169972281 Heater case slider grommet
7. 1168350098 Upper seal for blower motor case
8. 1169970481 Heater hose firewall grommet
9. 1079971581 Wire loom firewall grommet
10. 1169971381 Fuse box grommet
11. 1165001275 Hose from expansion tank to bottom of radiator

GenuineMercedesParts.com just emailed me and admitted their mistake. They will add 1168313394 (short 180 degree heater hose) to the order.

I got a big box of genuine Mercedes parts today! Fortunately, I was able to get many of the grommets I needed, but unfortunately some are no longer available.

I found the elusive not-listed-in-EPC condenser grommets. Yay! They are part number 000 997 31 81.

I took a risk on part number 116 997 02 81, hoping that it would be a suitable replacement for the no longer available air conditioning low pressure hose firewall grommet 116 997 24 81, or possibly for the no longer available right side heater core hose firewall grommet 116 997 04 81. Even though the outer lip on both are the same size at 66mm, part number 116 997 02 81 is made to fit in a 55mm hole, while these holes are only 42mm, so the grommet will not compress enough to fit. I tried.

The part number on my heater hose that goes from the right side of the heater core, through the firewall, and to where the climate control servo used to be has a part number of 116 831 28 94. It was superseded by part number 116 831 09 94. I put it up next to my original hose, and the new hose seems much too short and incorrectly angled?! I guess (hope) it will stretch and be fine, but wow... what a difference in size.

I bought a new temperature switch and got one that's made in Mexico--and the pin is tilted, like it was assembled crooked. Some quality control... I feel like I should return it. It looks identical to the non-Mercedes logo Behr ones I could have got for less money.

I'm also sad to announce that part number 008 997 17 81 is much too small to replace part number 116 996 16 81, which is the firewall grommet that has the vacuum lines going through it. Part 008 997 17 81 fits a 36mm hole, and the hole in the firewall is 46mm.

I don't really know what to do about these no longer available grommets other than to repurpose some decent fuse box grommets as air conditioning hose and heater hose firewall grommets, and use sealant on the others. I placed an order with https://www.sls-hh-shop.de/ for aftermarket 107 821 00 97 X2 vacuum line ducts for front doors, a 34mm rubber grommet which might work for the wiper motor wire harness at the firewall, a 42mm angled rubber grommet that may work for the air conditioning hoses and heater hoses at the firewall, and a 1169972281 heater case slider grommet. The shipping was outrageous and I hope their arrival doesn't take long.

I will need to make the inner hole bigger, of course. Sadly, I should have ordered two, as now I'll have to order a second one and pay for shipping again. Maybe I can find one at The SL Shop in England, or Authentic Classics for a lower shipping cost.

The 42mm angled rubber grommet 299003 from SLS is part number 113 997 01 81 and is still available from Mercedes, so I will order a couple of genuine Mercedes ones and the German aftermarket wiper motor grommet, rubber door ducts, and heater case lower flap seal will have to do. Haha.

So, now we may have a solution for some of those no longer available cowl/firewall grommets!

I also checked on the large rubber boot that goes between the heater case and the blower motor, as I discovered mine is dry rotted. It's part number 116 831 07 88, and sadly no longer available. Flex Seal to the rescue, I guess.

Yeah. That s the one. There should be a Paypal option though. Too many people do not want to send credit card data over the net. (like me) Also, you set the goal to 25usd. Is that the way? Should it not be higher, or doesn't it affect the system? It does not shut down after you reach 25, not? Interesting to see how that goes.

The genuine Mercedes grommets, part number 113 997 01 81 have arrived. They are better quality than the aftermarket one I got from SLS--the main difference being that there is no seam down the center, and they have a smoother profile, so they will look a lot better when placed on the firewall. The aftermarket grommet is pictured in the center of two genuine Mercedes grommets.

They will replace the no longer available right side heater hose firewall grommet 116 997 04 81 and the no longer available air conditioning low pressure hose firewall grommet 116 997 24 81 nicely once the inside hole is cut larger so the hoses will fit through.

I also found some plugs which will fill the holes where the vacuum lines come through the firewall to the servo, since I am removing the automatic climate control from my car. They are simply black 1/4" pull-through plugs ordered from McMaster-Carr.

When you're done with your quest, you could maybe organize orders for members here, where you order them all, compile sets in a bag, and sell/ship them to the members..

Ugh... I placed an order with Mercedes and nine items are no longer available, which include:

1. 1169970081 Seals around the cowl drains at firewall
2. 1165013682 Lower radiator hose (seriously?)
3. 1169971481 Grommet for auxiliary fuse box wiring at main fuse box
4. 1169971081 Grommet for wiper motor wire harness
5. 1078210097 Vacuum line ducting at front doors
6. 1169972281 Grommet for control into heater case
7. 1168350098 Foam at top lip of blower motor case
8. 1169971381 Grommet for main wire harness at fuse box, could double as heater core exit hose firewall grommet
9. 1165001275 Hose between bottom of coolant expansion tank and bottom of radiator

I guess I'll have to go aftermarket on the lower radiator hose and use the hose at the bottom of the expansion tank a little longer. It seems these grommets aren't happening, so I suppose the course of action left is to smear sealant all over them. It's too bad the W116 didn't use simpler, generic hose and grommet shapes with greater interchangeability between chassis types.

I've spent all day trying to find suitable alternatives for the parts that aren't available, but at this point in history it seems we must resort to wire and duct tape to keep our cars on the road as parts availability is failing. Even aftermarket parts availability is scarce. It makes me worry for the future of having this car as my only transportation.

They have their own exclusive parts stash, or make small re-manufacturing runs if the car justifies the expense. This is why some NLA parts re-appear and disappear just as quick from the catalogue.

That doesn't surprise me. I say we grab our torches and pitchforks and plunder their booty!

I purchased a lower radiator hose from O'rielly and it did not fit.  Too short.
Still looking for one that fits

Why would anyone make one; it's just a lower radiator hose, nothing important. Haha. Yeah, it's unbelievable that no one seems to make one. Was it the GATES 20700 that I purchased and still haven't installed? I hope not. I can tell just by looking at it that it's a smaller diameter and bent differently than the original, but hope it will still work.

AutoZone sells a DAYCO C70705, which is probably going to be a similar fit to the GATES 20700. You can also take your chances and order a ÜRO brand hose from eBay or AutoZone. Otherwise, you can use a beautiful universal fit flex hose. Haha.

Yeah, if the GATES 20700 hose doesn't fit, I'm going to be upset, because then I guess I'll be forced to buy ÜRO.

There is another possible option if you are patient--an Australian-made Mackay brand CH4421 (odd since the W116 300SD was never sold there): https://www.ebay.com.au/itm/Mackay-Radiator-Hose-Bottom-CH4421-/161881381605 (https://www.ebay.com.au/itm/Mackay-Radiator-Hose-Bottom-CH4421-/161881381605)

I may go this route...

they sell a lot of stuff, surely for much older cars then ours.

They sell universal rubbers, some of them designed to cut into shape yourself. Is that of any help? They are super cheap, that s for sure.

Interesting. I'll keep them in mind if I find I need more no longer available rubber parts.

The AutoZone DAYCO C70705 (made in USA) lower radiator hose seems to be a better fit than the O'Reilly GATES 20700 (made in [conveniently rubbed off]), just from looking at it. The opening at the bottom is larger than the Gates hose and closer to the size of the Mercedes hose. It also doesn't have the weird bend near the bottom. However, the upper bend turns forward instead of backwards, but hopefully those hose will flex enough for this to not be a problem.

In both pictures, the hose order goes, left to right: Mercedes, Dayco, Gates.

Apparently Rock Auto also has an ACDELCO 22058M, although when you look it up, it shows a Gates hose:
(http://www.peachparts.com/shopforum/attachment.php?attachmentid=149497&stc=1&d=1539480965)

They also have a CONTINENTAL 66483. I probably would have chosen it first if I had known. Interestingly, the hose in the photo looks identical to the shape of the Gates one and the lower opening also looks too small.
(http://www.peachparts.com/shopforum/attachment.php?attachmentid=149498&stc=1&d=1539480965)

I wish I could see a CONTINENTAL 66483 next to the GATES 20700 and the DAYCO 70705, but if it's anything like the picture above, it looks like it would fit the same as the Gates.

I just figure that if they are no longer available from Mercedes, or aftermarket, I'll probably find some universal part to replace it with. It's just a rubber ring, basically.
