Hello, I would appreciate any help re the position of the black metal Y pipe ,other black pipe and all connected hoses for my 1967 SL230. I’ve read the LHD Info on the forum but cannot work out the layout for my RHD.

I think I know what you're talking about but your picture isn't sufficiently informative.

Hello Stick , Thanks for your reply , tricky to explain but I’m trying to work out the correct layout of the two black pipes and connected hoses . That’s from the bottom of the main radiator to the heater matrix, rad reservoir and thermostat housing RHD. I know the route of the 8mm hose from the top of the main radiator to the top of the tank and the large hoses from the main radiator . Any help would be appreciated.

G’day Garry
Great photos your engine looks stunning, any more photos in particular if you have any of the engine bay when the engine was first removed . Also any others showing the two black metal water pipes would be greatly appreciated, thanks for sharing your photos.

I am not quite sure where you are referring to whether it is around the water pump and below or further down FIP side. Here are a couple more. I only have the one on the empty engine bay.

Thanks for all the photos very very helpful , the two black metal water pipes are pictured on the attached photo and any further details would be appreciated.

Esmo,
Are you sure they were black on original cars.

Hi again, here are some more photos. The pipe with the Y shape passes under the inlet manifold ( and is clamped to the inner wheel arch) and emerges below the servo. The lower branch is then connected to the other pipe with a short rubber pipe and continues to the underside of the coolant expansion tank. The upper part of the Y shaped branch on the first pipe then goes to the fire wall. The tab on the second pipe bolts to the fire wall behind the cylinder head.

Hello All,

To save starting a new topic, I thought I’d try asking on this one first.

I have a RHD 230 and I’m trying to find the part number for the pipe I’ve circled in red.

It connects to the y pipe then runs across the firewall to the coolant expansion tank.

I’ve copied the photo supplied in the post as my car is in bits. Credit due to the owner (Gordon), your car is in way better condition than mine at the moment.

If anyone can help me with a part number that would be a good start to the challenge of finding one.

Thanks Doug.

Hi Doug I think the Y pipe is 1138300115 LHD and 1138300215 RHD ,I’m unsure if the pipe your asking about is handed as I can only find reference to 113 831 05 85 , I would recommend you confirm it’s correct for your RHD before ordering .
Happy to be corrected as not 100% sure.
Les

The pipe that runs from one branch of the "Y" pipe along the firewall to the expansion tank on a RHD car, i think is part number 113 500 0072. Niemoeller have it listed as no longer available. Not sure if any other suppliers have it

I thought I’d gotten lucky when I found the “Y” pipe and ordered it from Authentic Classics last year.

Upon pulling the old ones down from the shelf it is different.

Looks like I’m up a certain creek without a paddle when it comes to finding these.

The old RHD difference has stymied me again.

I’d reuse mine, but the flares have corroded.

Bob you are right, I didn’t scroll far enough down on the Niemoller website to see the picture.

The two pipes needed are 113 500 00 72 and 113 830 02 15

Not sure what to do now.

It should be straightforward for a radiator shop to braze new ends onto that pipe, if the rest of it is ok.

Duncan200 · « **Reply #20 on:** March 13, 2023, 10:15:36 »

Hi Dave,

I thought that, just not 100% sure on the integrity of the rest of the pipe.

It’s been 3 years since they’ve been under pressure.

I’ll get a radiator shop to have a look and pressure test them if possible.

I think I might ask my plumber cousin if we can make something up in copper, a coat of satin black and no one will know any different.

Doug

It's a fairly easy fabrication job if you can find the right outfit to do it.
