Replaced seat belt tensioner

ok, today i took off old tensioner and put new one on which was easy but then i went to put on belt and for some reason it was kinda loose, then i figured out they gave me wrong size belt, so then i went and got the belt size that was originally on the car when i got it and now the belt is still just a lil bit loose, i was wondering if there is a way to tighten the belt more or ?. cuz i was getting a squeal when i tapped on the accelerator before i replaced tensioner, now i get a squeal when idle and no squeal when i step on accelerator. unless i really hit it. need help, thanks.

What brand of belt did you buy?

yes all you need to do is in the tensioner itself there is a plug you need to pull out and that will release the spring making the belt stretch and tighten up.... i had the problem and after a while we figured out that you need to pull that plug from the tensioner (it seems that plug is part of it but its not... its made to make you life easer .....hope that helps

Thanks, is the plug on the tensioner itself?

Thanks I located the plug and wut do ya know, it solved the problem, thanks

Bringing this old thread back to life. Got an error message today. After clearing the error with INPA it comes back immediately. Looks like my passenger seat belt tensioner needs to be replaced. This looks like it should be easy enough to do but I'm looking for guidance from anyone that has done this before or have any useful advice to offer.

Oddly enough my lite came on last week...is there a DIY for this doesn't sound to hard.....Thanks for any tips you can give....PM

what kind of error message do you get?

Not sure of exact wording ...but Ithink it's like tensionor needs replacing...then a little red lite with a seatelt through it..I'll check in the AM for exact wording...PM
Thanks

Did you ever fix this problem, I got the same thing in my 2003 745.

Got it fixed. I just had to reset it with my scanner. So far so good.
