It seems after consulting all the available information my tensioner is not standard.
First if you look at pic1 you can see its not attached with a tamper torx bolt but an E bolt.
then progressing (pics 2-4) around the pulley there are E bolts also holding on the tensioner assembly, but no boss in sight.
Not sure of the next move.
If I am missing something obvious feel free to give me a boot to the head. but im stuck.
thanks again for any info and or beatings im entitled to... lol

 

First off, is this an N/A or a SRT6 ?
If it's an N/A, then it is an odd tensioner by having the middle groove in the idler pulley, and no boss.
If it is an SRT6, then the ider on them has no boss. ( guess you could say it's independant, huh ? )
On the SRT6, you use the bolt to relieve the tension, I believe ( the service manual is not very clear on this )

 

spot on its an srt6. I appreciate the feedback.
i just wasnt finding the boss no matter how i stood on my head.

 

Use the bolt to relieve the tension, make sure you use the correct size star socket for it, others have used the wrong size and stripped the head. The socket should be the smallest one that goes on the head. I think it's a size E10.

Counting the ribs on the belt is a pointer to an NA or an SRT in pics like this.

 

just to be clear, were talking the bolt on the pulley?

 

Yes............................

 

I bow to your great abundance of wisdom.
thanks!
