How to Replace Serpentine Belt Tensioner 98-03 Dodge Durango 

√ *Watch the Video* √ *Buy The Part at 1A Auto* 1aau.to/m/Visit-1AAuto √ *Do it Yourself* √ *Save Money*

Just adding my experience here for reference's sake: The air filter box was held down with plastic reverse torx nuts, not 10mm nuts, and the coil had two 10mm hex head bolts that went outward toward the fender into a metal plate with two threaded holes. It was kind of hard to get to, and you couldn't really swing the wrench very far, but I had a short 10mm spanner that eventually did the trick. The truck is nice and quiet now (at least with regards to the belt). Thanks for the upload!

You have no idea how helpful this was. I was about ready to pick the truck up I was so upset I literally thought I could. I had no idea how to put the belt back on after I replaced the alternator! THANK YOU!!

I am replacing the belt on my2002 Dakota need help with routing placement of the belt

Thanks, Mike I didn't know you had to remove the coil to get at this bracket, but it's no big deal to do that. Dave

Hi there a1auto I’m a big fan! I jst have a question regarding on part where u need to put the serpentine back on. I’m having a hard time putting it bck. Is there any tricks on how to do it? Thanks

Mine is a 2000 Ram 1500 with more room to work with and the air filter is not in the way. I started with a 15mm wrench taking the belt off but ended with a 15mm short socket on a 3/8" breaker bar to finally seat the belt on the tensioner. (I'm and older guy.) Piece o' cake once you do it once but someone has to point the way and you did a fine job. Thanks!

After watching this video, I'd like to say "Thanks so much". The tensioner on "97 Dodge Dakota V6 snapped off at the bolt - I had fully intended to take it to the shop for repair, but your video convinced me that this will be an easy fix. Appreciate the detail you went into when you made the video - it was easy to understand, and you even mentioned the wrench sizes (nice to know in advance). I subscribed to your page, will be checking it often.

Your videos have helped me and saved me alot of money and time. Please add more 98 Dodge Durango videos

Thanks for all of the helpful, expert videos. I use them all of the time to take care of the minor repairs and maintenance that used to cost me $$$.

Great video, better than Haynes for getting the job done quickly and correctly. Thanks for posting.

I want to say thank you for your videos. You will be one Mechanic I will be following for a long time.

Great video! Not only did it help me replace my tensioner, but also my serpentine belt! Good job, guys!

Thanks for posting. I was stuck as to how I was going to get the nut off the tensior pulley off my 2001 Dakota as there isn't a whole lot of room, I watched your video and BAM, never thought of removing the air box to give myself more room...."facepalm"! After removing said air box, it was a piece of cake!

Thankyou for posting this information. I didn't have a clue on how to replace the tensioner unit !!

Great video! I am going to get to work on my truck today. Thanks guys!

Thanks a bunch! Helped me get my idler pulley replaced on my 92 dakota in no time.

Watching the video took out the guess work; thank you

As usual well spoken high quality easy to follow tutorial. Thank you! 🙏🏼

@jgonebyebye You're welcome. Thank you for visiting our auto repair channel on RU-vid.

@agnu7593 You're welcome. Thank you for watching.

thank you 1A Auto it worked like a charm. on my 2000 dodge Dakota

excellent just what I needed !!

Thanks 1A Auto for the very informative video. Go figure that the new Haynes manual I just bought does not describe this....in this detail.

@MrSpongejj2000 If you want to disconnect it,it won't hurt anything.

Thank you for posting this video because I used it the other day to replace mine (the large plastic wheel part of the pulley broke from its axis and flug out onto my driveway. The only issue I had was that those 2 bolts holding in that other part on my '02 did not have nuts on them the way yours appeared to. With your Durango you were able to put a wrench on the backside and then use another on the easier-to-access fender side and crank. On mine I had to crank from the side facing the engine and it was very hard to get to!

I dropped the nut on the back and can’t find it. What size is it?

Thank you for this video! Super helpful 🙂

Some good advice in here. Thanks!

Thanks a lot man I really appreciate this video, it would of cost me a lot more if I would of taken it in! great video.

hey buddy thanks for this video your very accurate gonna attempt this myself and save me some money...Happy New Year..

Great video. I am very pleased

Thanks great video and keep up with the videos.

i love this, keep make videos guy

My Timing Belt keeps riding up on the rail of the crankshaft pulley. It looks to me like the crankshaft pulley is not exactly in line, but I'm wondering if the tensioner is the culprit? Thanks, I just noticed after a DIY waterpump/thermostat replacement on a 94 Dodge Dakota Sport 3.9L V6!

*why* would they mount the coil over the tensioner pulley? wow.... anyway, thanks for the video. good reminder about the idler 👍

Do you have to disconnect the battery, since you are messing with the coil?

Will this stop the annoying squeak on my 2003 dodge Dakota?

What size belt do I need for an 03 Dodge Durango 4. 7 is it two different sizes

3:00 Some stupid fool used Phillips head bolts to hold my coil pack on with. They striped out just looking at them. Now I am going to have to remove the whole mounting bracket and cut the Phillips head bolts out. I may even relocate the coil while I am at it.

very helpfull,, thanks a lot !!
