Finally convinced the dealer my water pump was leaking. For months now I have occasionally smelled coolant when waking in front of my vehicle. I could never see evidence of a leak. I started monitoring the level of the overflow res and found it to be losing about 1/4" per month (this is after the dealer supposedly pressure tested the system and found no issues). This time, I took the picture evidence of the fluid loss and they agreed to take another look. This time they found the water pump to be leaking ever so slightly behind the pulley. It was replaced under the powertrain warranty. If any others are having similar symptoms, have the tech check the water pump by removing the belt and wiggling the pulley. Mine had some fore/aft play and when wiggled it would seep coolant out. Problem solved!!!!

Hey thanks, I'll lay this on my service guy. I had a coolant slow drip leak at 250 miles that turned out (so they said) to be a the timing chain cover gasket so they pulled the front end off and replaced the cover (gasket is integrated) and stopped getting the small drip but I always had the coolant smell 100% of time but with no drips I could find I was stumped until I had this under her a few days ago. You can see the highest coolant drop is on the top lip of oil pan which puts it right behind the pulley....jackpot, funny how Mopar water pumps have always had a bad rep....wonder why....

I had my water pump replaced by the dealer a few months ago on my 2013 Overland with 20,000 miles on it. I notice a small puddle every once in a while in my garage. The dealer was the one that found it when I was in for other warranty items. They said they could smell it. Love my Overland.

My Dads water pump is leaking too. Pretty sure its in the same location, behind the water pump pulley.. I pulled the intake off and fired it up. Sure enough it is whipping off the belt in a fine mist. Any body changed their own water pump?

I haven't but these are the FSM steps:

1.Disconnect negative battery cable.

2.Remove the air intake assembly (air cleaner).

3.Remove the resonator mounting bracket.

4.Remove cooling fan assembly.

5.Drain coolant into a clean container .

6.Remove the upper radiator hose from the thermostat housing and position aside.

7.Remove serpentine belt.

8.Remove idler pulley.

9.Remove belt tensioner assembly.

10.Remove lower radiator hose from the water pump and position aside.

11.Remove the upper metal heater tube from the cylinder head.

12.Remove water pump mounting bolts and remove pump.


The fan/shroud assembly is held to the radiator by clips. You may have to removed the belly pan to get at the clips. The FSM says to disconnect the AC line to get the fan out, dunno. But thats an AC evac/recharge.

I just changed the pump. One of the easiest pumps to change! Pretty much only need a 10mm socket, 13mm socket, 15mm deep socket, 3" ext., 3/8 ratchet, and a couple regular hand tools. No need to pull the fan assembly either. The toughest part was pulling the metal heater tube out of the pump. Could be done in a parking lot if necessary.

Found where mine was leaking also. There was a steady stream coming from a small port to the passengers side of the pulley (from the front, 8 o'clock on the pulley). It had been leaking or dripping for the last couple weeks. Just got around to changing it today.

That small port is the sentinel hole to let you know your pump bearing and or seal failed. Most pump failures start with the bearing going , which then takes out the deal.

Started hearing a loud rattle noise coming from the water pump recently, and decided I'd finally take it in to the dealer for an oil change, re-calls done, and the water pump checked out. Sure enough - the water pump was toast. The dealer took care of all of it, and they had all the re-call kits, and spare water pump on hand, so no delays, and the only cost to me was the oil change. Seems like quite a few have had to replace water pumps recently ... ?!

Thankfully the water pump on my 2013 V8 was replaced under warranty back in 11/14 before I bought it in January, 2015.

Having owned many Mopar engines, the only water pump failure I have had over 40 years happened at 180,000 miles on a WJ JGC with a 4.7 V8. Cost me $100 and an hour of my time .

I would not say Mopar water pumps are generally bad. Maybe the ones installed on the Hemi engine would be a better statement that

Experiences vary....my '14 Summit is my only hemi I ever had....My '02 WJ 4.7 HO munched 2 water pumps, early like 20k ish then 160k ish...only ate about 4 on about 10 '67-'72 V8 (318-440) mopars I played with in high school and college but those were all used so who knows how hot previous owners got them or dirty the system was. Maybe my drag racing had something to do with those

Didn't make any noise, and the shaft play was very minimal. But it defiantly showed when you popped the hood. The drip whipped off the pulley and misted everything under the hood.
