A variance in the tension is what causes your belt to slip or fray, and if left un-serviced for too long, it might even snap.

The first step is to disconnect the battery as you will be working around the engine.
It's cheap insurance against accidentally touching an electrical connector or terminal and causing damage to the vehicle's electrical system.
Move over to the passenger side of the engine and remove the fuel tank vent valve. It is located right above the tensioner See Figure 2.

Pull the tab on the side of the plug and pull it off. Lastly, push the tab to the side of the valve and remove it from the engine See Figure 6. Now, place the serpentine belt tool over the belt tensioner and pull toward you. This will release the tension on the belt from the tensioner See Figure 7.

I havemiles and I'm debating on whether to change it or just change the idler and tensioner pulleys.
I've regreased the pulleys a few times by popping the seal off the bearing, packing in grease, and then putting it back on. But when colder temperatures in the morning I can hear some noise, so it may be time to at least get the pulleys.
The bearings seem fine, but the noise was coming from that side not the power steering pump side. I don't think it is that common of a problem with the Daks though, They had to otrder the whole assembly. Why did you have to replace? Did it break? I've heard stories on other cars or breaking and causing damage. I'm somewhat concerned as I'm planning long trip in a few weeks. It just started to get weak and allowed the belt to slip.
Especially after it got wet. The belt slipped so bad, it started to smoke!! It was kinda funny. I ordered mine through Advance Auto. I would go ahead and replace it for peace of mind.

Do I just unbolt the tensioner and slip off the belt and install the new belt? Thanks paul. Then remove the whole tensioner assembly. It is a pretty straight forward cut and dry process.
It took me about 15 minutes to complete the whole process, no big deal. It is basically a clock spring mechanism that keeps tension on the serpentine belt. Good Site.
