Check these Chilton instruction on Dodge timing belts.

If you're keeping the car, change the water pump and the crossover tube as well.

The tensioner is not as simple as the 3.0. You may need a special Mitsubishi tool to set the tensioner by the book.
Thanks all for the responses. I looked at the Autozone diagram and that tensioner is different from the 3.0L V6. Is it a spring tensioner or is hydraulic and uses engine oil pressure to keep tension on the belt? I am not too worried about needing the proper belt tensioning tool. In the past I have always set the tension such that I am just barely able to twist the belt 90 degrees on its longest travel between sprockets. That has always worked for me.

From Autozone instructions:
Reinstall the tensioner to the block, but do not tighten.
Using special tool No. MD998767 and a torque wrench on the tensioner pulley, apply 39 inch lbs. (4.4 Nm) of torque to the tensioner. Tighten the tensioner pulley bolt to 35 ft. lbs. (48 Nm).
With torque being applied to the tensioner pulley, move the tensioner up against the tensioner bracket and tighten the fasteners to 17 ft. lbs. (23 Nm).
Remove the tensioner plunger pin. The tension is correct when the plunger pin can be removed and replaced easily.
Here is a link to a substitute tool for MD998767. The pics will give you an idea how this tool is used. You still need and inch pound torque wrench to use with this 1/4 inch drive tool. http://www.3sxperfor...e.com/tools.asp
Here is a link to a TB change on a Dohc Mitsubishi V6. Similar procedure but not identical. It does describe use of MD998767 and a torque wrench. http://www.team3s.com/60k.htm
Here is Mitsubishi document describing how to set the tensioner on a 4 cylinder engine using MD998767 or MD998752. The principles are the same as on the Chrysler 2.5. See step 29. http://www.dsm.org/t...tbelt/tbelt.htm
You might be able to judge when the tensioner plunger pin can be removed and replaced easily and skip the special tools.

You may want to change the water pump while you're in there.

If your litlte 6 is the same one as in our Sebring the belt change is no fun.
The pin advise and your ideas are all good ones.
Yes, definately change the water pump while you are in there.
Mark all the bolt for replacement there are different lengths to deal with.
Make sure you get a chance to diagram your entire job and let us know how you do.

shredded the serpentine belt. The serpentine belt got under the timing belt cover and wrapped itself around
timing belt crankshaft pulley causing it to slip a number of teeth (it was 5 off when pulled). The timing belt
was intact but all 12 exhaust valves and 2 intake valves were trashed. Fortunately there was no damage to the
pistons but one of the valve guides had to be repaired.
