I have a W163 99 and only recently found that the coolant was leaking. Found the where it came from, however I have no idea what that part number is, let alone explain it to the local dealer. If anyone can help that would be much appreciated.

The top joins to the coolant reservoir - didnt trace where the other 2 horizontal pipes goes as it was starting to rain.

Its an Australian right-hand drive vehicle if it makes any difference and is it as simple as squeezing the 3x pipes, replace and release?

 

I think you're looking at 16 right? I'll try to find the P/N for you.

Awesome - thats the part. However it appears reversed in my car where the hose going into the engine is going left as opposed to right.

At least I can ask the local wreckers for this part. Thank you heaps RollTideW163
