The leak is from the front side of motor, on the right side directly behind the serpentine belt. I will have to take another closer look when I get home. I'm not over heating just has a slow leak when it gets hot. It leaves a small puddle...keeping an eye on my overflow container.

Ok, wasn't hard to figure out it is only a water pump. So looks like auto zone sells for $37.99 which says includes gasket, going to put new serpentine belt on $27.99, and probably go ahead and buy a manual for $26.99. Going to replace pump even though I don't have any other issues , 53K can't hurt. Looks like I just have to loosen tensioniimeter and then pull the pulley and pump. Are there any special tools required to remove the pulley? And what coolant is best for the 3.8?

You want HOAT coolant for the 3.8. It's a five year coolant so if you haven't replaced the factory fill, now is a good time. Mopar sells it, but ZEREX g-05 is probably a lot cheaper.

The pulley is bolt on, so no special tools required.

There are write up on changing the water pump on the forum.
