Re: [MBZ] Mercedes 2004 E320 4Matic Belt Tensioner Assembly Question.
Go with an OE rebuilt water pump. About the same price as aftermarket but with a better (2 year) warranty. -D > On May 13, 2021, at 8:46 PM, Robert Koziak via Mercedes > wrote: > > Hi All, > Today I decided to change the serpentine belt on my 2004 E320 4Matic > w/90K.

Re: [MBZ] Mercedes 2004 E320 4Matic Belt Tensioner Assembly Question.
I have a W210 chassis with the same engine. I don't recall having any issues removing the bolts for the tensioner. (Alternator, yes) You might try soaking them with your favorite penetrating lube for a day or so. I got a tensioner at Advance Auto Parts and it was a Litens, made in Germany, IIRC. You may resort to an induction heater on the head of the bolts to break the corrosion bond between the steel and aluminum. Yeah, they aren't cheap, but they are cheaper than a timing cover, or perhaps a Helicoil job. Plus they are useful for other rusted nuts and bolts and WAY safer than an open flame of a torch. I have an attached garage, and I have no desire to rebuild my house because of stupidity. I do enough dumb stuff.

[MBZ] Mercedes 2004 E320 4Matic Belt Tensioner Assembly Question.
Hi All, Today I decided to change the serpentine belt on my 2004 E320 4Matic w/90K. In addition I wanted to change the belt tensioner assembly and pulley just to head off any future issues. I was able to change the pulley but could not get the lower torque bolt on the tensioner assembly loose. I put quite a bit of force but stopped because I was afraid it would snap off and cause some major issues! Thought of applying heat but it is not easy access to get heat on that bolt location. Anyone have a similar problem or suggestions? Since it really wasn't necessary I was considering just changing the tensioner assembly pulley. Mercedes Benz doesn't sell just the pulley but Rockauto does.thoughts? Lastly while changing the belt I found the water pump bearings are very loose so that's my project next week. Suggestions on the best water pumps? Thanks in advance!
