How to take the serpentine belt off of a 1994 Dodge Grand Caravan?

August 11th, 2011 · No Comments

I have a 1994 Dodge Grand Caravan SE with a 3.3 liter V6 engine. I am replacing the alternator which just died and also the serpentine belt which is cracking. My current issue is with getting the serpentine belt off. I know there’s a tensioner pulley but I have no idea which one it is.

- If you do your own work, go get yourself a manual, it will take you step by step (and with pictures) so that you will be able to find it, and do the job without breaking anything! “Haynes Auto Repair” manuals are as good as they come, – and cost about $20 or less at lots of auto parts stores (I buy mine at AutoZone)! Get a book for your year and model – it tells you how to do everything except rebuild transmission! I’ve only been at it for a little over 55 years, but I buy a manual that covers every car I get, – it saves me time and money (and possibly breaking things).
- The tensioner pulley has a nut in it’s center, probably about 15/16″ or 21mm. Or it may have a 1/2” drive square slot, that a 1/2” breaker bar is used to rotate.
Using the correct size wrench, and being prepared for a large amount of tension, rotate the tensioner via the pulley nut. Or via the breaker bar,as the case may be. It will only move in one direction.
It might take two people, one to hold the tensioner while the other removes/replaces the belt. You might be able to jam your wrench in place, be carefull, it has alot of resistance. Once the belt is off, check the tensioner by spinning it and listening/feeling for noise/vibration/roughness. If any of the afrementioned is present, replace it.
- The tension pulley is on the right side when looking from the passenger seat. It takes a special tool to release it. It has spring tension. The tool looks like a long bent tire iron. I think all serpentine belts are cracked after a year or two, that doesn’t mean it is worn out. If its the original it is probably due for replacement however.
