I believe this short coolant hose is leaking on my 1988 Mercedes 300SEL and I have been told that I would have to remove the water pump in order to replace it and it was not as simple to replace as it looks. Can anyone else verify? Gosh, seems like alot of labor to replace this. Hoping if so I can tighten it and it will be OK... its a very slow leak at this point. Its also kinda rusty there around the hose area.

Thanks!

Wow... 45 views and no one knows.

If I were you I will tear open the old hose by making a horizontal cut through the length of it without removing anything except the clamps. If all the parts are OK, I will then sand and clean everything extremely well (including removing rust) and apply a good amount of WD-40 or Vaseline to the inside of the new hose and try to slip it through the opening by going all the way left first and then right and make it centered. Attach new clamps and presto! Although, you have to see if it fits through the opening in between both necks, you have nothing to lose by trying my approach first. Needs patience and a cool head; let me know how it goes... Good Luck Buddy!

Thanks. Well the hose was leaking on the side toward the thermostat, so I went and bought a new clamp (wider) and replaced it. I also moved it more toward the end of the hose. It appears to have stopped... for now anyway.

Thanks again!

Update... 11 days later, has not leaked a drop! Apparently it was the old original clamp causing the problem! Thanks!
