2011 Overland Summit - 2nd Water Pump Replacement?

Hi Folks,

A few months back I posted about 2011 Overland Summit (5.7 L) leaking coolant. You can see the thread here. http://www.jeepforum.com/forum/f309/...-help-2414113/

In the end (May 2014) the dealership ended up replacing the water pump under the powertrain warranty and the problem was gone...for a while. Today while I was checking all my fluids for a road trip I have in the morning I noticed some dried up coolant specs on some of the hoses near the water pump.

It appears as if the water pump is leaking a small amount of coolant again although not nearly as bad as it was before. This is somewhat concerning for me as my GC is now at 83k miles and I planned on keeping well beyond the powertrain warranty expires. If these water pumps are in fact this unreliable I may look into replacing the vehicle with something else. The problem is I don't really like any other SUV as much as the GC and I'm not a big fan of the 2014 front end.

Any thoughts or opinions on this issue?

I've not seen anyone else post about this problem in the several years I've been on Jeep related forums. In thinking about this, is it a water pump issue, or is there a problem with what the water pump mounts to that is causing the leak that subsequently causes failure? The seals or the machining on the engine where the seals and pump mount...

Agreed. When I get back from this trip I will be taking it to the dealer for a follow-up to see what they think is the causation for a second failure. I'll have them take a look at the mount that the water pump bolts to for any defects that may be causing coolant to pass through.

Yea, it doesn't make sense that the "pump" is leaking...most often, leaks are at places where two things are joined together ineffectively.

My 2010 had the water pump replaced at something like 62K miles. Just as a datapoint. My WS.6 Trans AM had a water pump die at about 83K miles. My mustang 5.0 with a flex-fan and a 7K rpm revving cammed up 302 with aftermarket heads at water-pumps like candy. One every 5K miles or so.
