[QUOTE=Isaacmaple08;984539]As some folks are probably aware they stopped making the SRT6 Tensioner and you can't find them anywhere except for Pick&Pull/Junkyards and Ebay. P/N:A1122001070

A few people PM'd me about the tensioner in my post in #7907 in the What did you do to your Crossfire today thread.

Anyways thought I'd update that Rob w/ NeedsWings has a few original ones left, but what I found was that there is another part number that fits our SRT6's P/N:A1122000370. They're going for around $40 on ebay now, I picked up 2 and mounted one and it works without issue. not sure if they still make them.

Just a heads up. Pics of it attached on
Remember that the part from the SLK32 will work as well, I am sure that the part is used on other Mercedes models as well. Your part was first used on the 112 models whatever that was.🤔
Both parts you mention are the same basic part, the first six numbers are the same, 112 is the model number and 200 is the part group number. The last two numbers 70 is the item number and the two numbers before that are the revision number to that item. So your 03 number is an earlier version of the part from the Crossfire SRT6.
Someone will say I wasted time explaining this but it helps find parts that fit, but some times the revision will make it unusable.
