Need help finding a specific hose om602 - PeachParts Mercedes-Benz Forum

I made a thread on this before and got no answers. It's what I believe is a coolant hose and it's on the passenger side of the engine below the turbo. Smaller diameter than the coolant hoses that attach to the radiator. It it's two hoses clamp together in an elbow or 45 degree hose. Does anyone know the part number or where I can get it. The dealer is clueless amd can't find it and not many cars on the junkyard near me.

If the 602 is anything like the 603, that "small" hose is part of the lower radiator hose.

If that isn't what you're talking about, a picture is about the only thing that's gonna get you the answer you want.

Could it be 2108323594, (pane washer water heater hose)?
Item 62 in the diagram in the link.

A picture is worth a thousand words, so let me help here. Here's a photo of a 602 lower radiator hose, the only significant cooling hose on that side. This bag of snakes is a dealer-only item these days.

The only other coolant hoses on that side of the engine are the overflow hoses for the header tank, and maybe a water pump drain hose and a couple of connectors for the heater return.

There are hard lines for the turbo oil feed and drain, and a few small vacuum lines for the EGR controls, including a u-shaped hose and a filter for the vacuum transducer(s). So if it's none of the above, you're going to have to post a photo.

I think that is it.. I'm going to go look and take a pic today once my camera is charged.

What's it for and what is it? Definitely has to be a heater hose!

That's pretty odd. The 124 602 heating circuit is in this jpg. The 201 version is even simpler.

So I'm guessing that is a heater hose then Frank right? Should the dealer be able to find this for me?

What I'm saying is that I don't know the part. If it's an original hose, the PN should be molded in somewhere.

I could be wrong, but that appears to be part of a WVO system maybe? I see a plastic hose barbed T there, and that usually is for a WVO heater. Worst case is you can just replace everything with new heater hose and fittings.

The hose PN on my OM602 from 1992 is 1248324893.

How do we source this?

Wonder if down the road as parts are no longer available if we can take flexible heater hoses (universal ones) and put together T's an elbows to fab them?
