Replacing the water pump in a 2013 ford taurus with the 3.5l engine is one of the larger services that you will have to do. the hard part is accessing the water pump because it is under the timing cover in an inconvenient part of the engine to access. in general you will be looking at $ 150 to $ 250 for the water pump part itself. the labor costs will be $ 350 to $ 500 depending on the local labor rates in your area. that means it could cost $ 500 to $ 750 to replace it depending on a few factors. the water pump is very important because it is what circulates the coolant through your engine and back to the radiator so it needs to be replaced about every 100,000 miles.
This costs about $ 250 for the part and you are looking at about $ 400 for the labor. so total of about $ 650 - $ 750 to do this job.
Just had mine go out, 2013 ford taurus sho. dealer quoted me $ 2,400+ without doing the timing components and $ 2,600+ with.
At the dealership $ 1700. it's in a bad spot and very labor intensive. they have to remove the timing chain to access the water pump. possible design flaw.
