2013 Taurus slowly losing coolant

Post by smitty79 » Tue Sep 12, 2017 9:38 pm

My 2013 is very slowly loosing coolant. I'm down about an inch below "cold fill" when the engine is hot. Anyone else experience this? Should I be concerned?

If you don't see coolant on the driveway, it's not likely good, my friend. It can be many things, but slow and steady loss like you describe is usually an indication of a weeping water pump. Do a search for ford 3.5L water pump failure and you'll get the picture.

A weeping water pump is not generally bad news in most cars, but unfortunately, the Cyclone engine design has a chain-driven water pump and it's behind the timing cover. Water weeps out of the pump and down into the oil pan sump. Eventually, the water content in the oil is too much, the oil looses it's mojo and the usual results are terminal. Spun bearings, which means new or rebuilt engine. It's also all or nothing...the engine is usually fine and then it's toast. There is no slow deterioration.

Get your oil changed right away. Ask them to keep the drained oil so you can see if it has any water in it. If you change it yourself, obviously, do the same. While changing the oil is not the answer, it will help you diagnose the problem, and you'll get the water that is in there out, and fresh, uncontaminated oil. Do it NOW.

The water pump is an awful job, requiring either dropping the engine, or some very creative wrenching. The worst part is it's a $60-80 part and up to $1k in labor. Not great, but still better than a $4-5k engine job.

I'm sorry if I am scaring you, but you should be scared. The incidence of the problem is technically low, but it is common. Enough to be a well-known and documented problem with this engine design. I check my coolant religiously for this reason. Get it checked and fixed asap.

The use of an internal water pump on the NA V6 in the Taurus, Explorer, Edge has steered me towards a NA inline 4 on the Fusion for my next possible car purchase. I currently have 293k on my 2005 Five Hundred (which still has the stock externally mounted water pump). I simply do not understand why Ford chose to go with an internal water pump. Packaging perhaps?

What I read, the internal pump design kept the motor small enough to fit in most small engine bays so cars didn't need complete redesign to use it.

Warment - same here. I'll go back to Fusion with I4. I gave my 2006 Fusion (2.3L I4) to my brother in law and he's racked up 230k and she's still running strong.

Another question - is it normal to have some evaporative loss of coolant? The car is approaching 5 years old now. Is it normal for some coolant to exit the weep hole without it meaning the water pump is about to fail? I have work buddies contradicting each other on this and I don't know who to believe... Kyle has me convinced that these aren't normal occurrences. I'm having my dealer run a pressure test on Monday..

I think it is probably normal to have some evaporative coolant loss. However, I don't think it is normal to have coolant exiting the weep hole.

Update: Dealer diagnosed this as a slow leak through the bottom seam of the radiator. The radiator will be replaced. I lucked out on this one. Hopefully, the WP will continue to behave.
