Bad design having it internal. Mine was replaced at 82,000 miles. $2200. I saw yesterday that a class action law suit has been filed against Ford over the water pump issue. It would be a nice surprise if they issued a recall in response and i got reimbursed for some of my cost.
2013 Taurus (166,000 miles) has had a ton more issues than that of my 2007 Explorer (235,000 miles), and my wives 2005 Freestar (200,000 miles)
Now rear passenger side door lock is having issues and door wont open from inside or outside. Unless you pull up on lock at the same time i hit the unlock button.
Radio /cd randomly doesn't work after start. Have to remove key, get out of car and wait 10 sec then restart. then sometimes it will work again.
Ready to be rid of it and get something else.

I started to see issues develop with my 2010 with 114k miles. PTU leaking, trans lines leaking and I kept up with maintenance. So far my 2013 with 81k seems to be holding up well.


If I were you I would cut my losses and get rid, before it becomes an endless money pit.

Should I be concerned that I got my water pump repaired at 84,000 miles and now I am at 164,000?
Might it go again after 80,000 +/-, or does Ford repair make life longer?

Speaking of now that this is concerning me, should I personally be aware of any maintenance or things to do to maintain my Taurus specifically? It's at almost 80k and has been dead reliable, however I'd rather not display my luck and have something happen out of nowhere.

I'm just unsure of what specifically should/must be done at what times.

I think always the biggest worry is the dreaded water pump failure. I change my coolant at LEAST once a year.


We can all keep up with maintenance meticulously and even then things fail. Easier said than done but try not to worry too much about it. As long as maintain it there is nothing else you can really do.


I'd just say be very strict on keeping up with maintenance and maybe complete tasks before Ford say it should be done (such as "lifetime" PTU fluid, or "lifelong" transmission fluid etc.

How often have you changed the coolant since the new pump install? Did the other pump fail?


I'd just be mindful of coolant changes and do them more regular than Ford recommends.

Well that brings me to my next situation. I've done a brake fluid flush, transmission flush, intake cleaning, fuel system cleaning, new injectors and spark plugs, etc. I actually have never done a coolant flush and probably should, but I'm unsure how.


I need to install my ported lower intake manifold but, of course, the water pump is inside the lower intake so the collant must be flushed to remove that and install the new lower manifold. My service manual specifies it must be done with a machine in order to refill the system with coolant after it's drained which sounds absurd to me.


So if I may ask, what's the procedure to flushing all the old coolant and refilling some new stuff in there?

My friend owns a NAPA repair shop so he does it for me. However this video may help

I don't know that changing the coolant will prevent the failure, but it really can't hurt. The PTU is another story.

It might be smarter to squirrel away $1200 for a rainy day.

If you're at 80k now and doing well, I'd probably pay Blackstone for an analysis on your next oil change, if only to find if they're seeing coolant traces in the oil. If not, change the coolant but know that things are looking good for that moment.
