On my '95 S500, there is a hose which attaches the overflow tank to the radiator and has a tee in the middle for a separate hose; where does that hose go and what does it attach to? Thanks.

James, MAVA alerted us to this tee and fittings. Should be replaced. He suggested a brass or bronze replacement from the hardware store. Seems to me that when I replaced mine the whole thing came as an assembly.

Thanks for replying, Anziani, but my question was where does the "center" hose on the tee go and to what does it attach? It seems it goes downward in front of the engine???

James, you forced me in to opening the hood and looking. Yes it disappears into the front but I sure can't follow it without pulling the radiator(?). mine is new and came from the dealer. One end goes to the top of the thermostat and the other end goes into the top of the overflow tank. I'll look in my AllData subscription and see if I can get more info.

The only thing I could find on ALLDATA was reference to a "air" line that has a cap on it and terminates next to the windshield washer bottle. Apparently one removes the cap from this hose when removing the expansion tank. Yes, I'm just as confused as you probably are.

Hose

Thanks, Anziani, for looking into this. I'm perplexed by this hose "thing," as I can't see where it goes (except toward the bottom of the engine). Frankly, I'm too old (82) to get under the car and look, so I may have to wait to find out until I take the car to have the tee "thing" and hoses at the back of the engine replaced (that will be soon. since I definitely don't want a problem to happen back there).

I am perplexed too.

Aren't this thread about the breather tube (MB p/n 1405000972 on the v12; p/n 1405000672 on the v8)

On the v12, one end goes to the overflow/expansion tank, one end to the thermostat housing (the longer arms); and the shorter end connects to a nipple up on the upper corner (pass side for us in the US) of the radiator.

This picture shows my old radiator. The nipple is barely visible in the upper right corner:

Nothing should disappear deeper below the top of the radiator.

Hope this helps.

PS I am half your age (God bless you) and already feel the pain getting under the car....

The v8 is likely very similar in this regard.

hose

I must correct myself. That "center hose" doesn't go toward the bottom of the engine; it goes to a radiator connection (upper rad, passenger side), just as Steve said. Not easy to get to, but doable for sure.
