One of my alternator belts broke last week. I have not touched the belts since I bought the 300DT and who know how old they were when I bought it. My guess is I put about 30k miles on the car under my ownership. How long do the belts usually last on the 300D? I love the double belts on the alt. I have to place an order for all new belts including AC (currently missing) and try to get the AC working. That'd be nice!

Try for a matched pair. Not buying a matched pair is probably why my replacements did not last long. Actually I also was not overly impressed with the continental belts even though they have a good reputation.

So I went to a full line auto parts store and selected a pair of sae utility belts that are a little thicker in cross section. They do not centre rub and have seemed to stand up very well so far. No initial stretch adjustment after a little use needed I noticed..

Time will tell but they have better traction I believe than the continentals did. They ride just a very small amount proud or above the pullies. We wil see how that works out when they eventually wear down a little.

Five dollars apiece here and probably less in the states. I just went out and checked they are 39 inches long with the first sae cross section larger than the continentals and there is now a slight amount of run in stretch.

Not enough to re adust the alternator tension yet by any means but it is there. It appears they have settled down in the pullies as well. They are now no longer proud of the pulley tops at all although it was a very small amount originally. At this point I am unlikely to go back to the specific metric belts.

That could change just unlikely to. Also a 39 inch belt of this type gives you a start position with a maximum alternator adjustment available down the road. The new continentals were centre area of the adjustment range on initial installation.

There is something to be said for serpentine belts with the tensioners used today. Vee belts will always need retensioning over time. Incidentally the car is a 1984 300d.

Its easier when you have no A/C compressor mounted to the car anymore.

got it done.... lots of fun.... I wanted to do it asap. Got me NAPAs premium (Gates) belts. All in all it took me about 2 hrs. I had to go get a 17mm rachet box wrench. it makes it easier to loosen the alternator since its tight space down there. I hate it when I misplace my tool and have to get a new one.

Over tightening can also cause pulley failure.

how would I know if its too tight? I've always tried to keep a play of no more than 1/2" when you push a belt between pulleys. Without a tool, the question is at what pressure?
