Chrysler dealer here in town said it would be over $2000 for the head gasgets. They Said $700 for just the water pump. Parts alone for the 3.5 (head gasgets, other gasgets needed for chainging) are $300+ if you go all aftermarket. add in water pump and timing belt ($120+), tensioner pully (if needed, $50). Took mine to a garage instead, got the price down to $1500 to get it done (including Cutting the heads and cutting the valves/valve seats). Couldn't justify $800 and 3 weeks or more of my own work outside in the Cool wisconsin fall to do what they got done in 4 days.
