Tool to Replace Serpentine Belt and Release Spring Tension Pulley
 

I want to replace the Serpentine Belt in my 2000 Marquis.

Do I need to buy a special tool to release the tension pulley, or is their something else that I could use, like a Breaker Bar?

What would you suggest? If a Breaker Bar, what specifications would you suggest?

Thanks.

You can use a long ratchet or a breaker bar. Look at the size of the square hole and use proper size tool.

I agrees with way2old. These are super easy (compared to some of the other cars on the road) to get belts on and off of. I think a 3/8" ratchet is all that's required.
