How much would it cost to replace the water pump on a 3.5L 300M?

The water pump in my 2000 chrysler 300m is starting to fail - how much should I expect it to be to replace/repair.How much would it cost to replace the water pump on a 3.5L 300M?For a used part, request a quote from somewhere like Greenleaf Auto Recyclers or car-part.com ... for a new part, call your local Chrysler/GM dealer, ask for the parts department, and ask for the cost of the part. While you're at it, ask them for the repair time to replace the water pump. If you can get that, multiply the repair time in hours by about $100 (what places charge around here for mechanical work) and add the cost of the part.
