anti-freeze leak
Hello all,
I am new here and I was hoping to get a little help. I have a 1990 300E with a straight six. I've noticed lately that I'm getting a small amount of anti-freeze on the driveway every day. Also the anti-freeze level goes down about a 500ML every week. I checked all the hoses and saw no leaks there. (the hoses are all new) I then check the radiator and found not sign of leaking. Then I took off the large splash pan under the engine between the tires and I found some anti-freeze there. So I looked up and around on the driver's side of the engine from under the car and found a very strange. I is a black hose, about 6mm. One end was hanging lose and when I touch it a small amount of anti-freeze came out. The end of the hose is about half along the long axis of the engine on the driver's side. I pulled on the hose and it did not come loose. So I tired to trace the hose to where it came from but it gets pretty crowded on that side, however the best I can tell it seem to go into or very near the back of the water pump. Can any one tell me what this hose is. Of course I realize anti-freeze could be dripping down on top of this hose from another place. Please respond, if you know what this hose is for have any other ideas. Thanks!! Nina |

I'm kinda guessing, but I get the impression the hose is there to direct any water pump leakage safely to below the engine. It's probably a worn out water pump that needs to be replaced.
If you still need further verification whether it's coming from inside the hose or dripping on the outside, pack some absorbent material around the outside of the hose to stop any drippage and see if it still leaks from the hose end.

You probably need a new water pump. I replaced mine last January, in the cold 30 degree weather. Also, you kight want to get a complete set of hoses for it.
I did a search for you: M103 91 300SE water pump replacement pics and http://www.peachparts.com/shopforum/search.php?searchid=154626 A search on 'm103 water pump'

You may want to take a close look at the upper timing cover right below the distributor. I had a similar problem with tiny trace of antifreeze leakage which I located to come from where the upper timing cover meets the main timing cover. The seal itself cost only a few dollars, but it was quite a job to get it done. The radiator and fan had to be removed to allow room for proper work clearance. Worth a look, good luck.
