Water Pump Recall

[jhenderson]

Well, I have one of the affected pumps (no vent hole), and my local dealer says I`ll receive a notice when the pump is in stock.. Might never see that day.

Pump started making a grinding noise on startup (checked with my stethescope). Ordered a new pump, tensioner, belt, and Zerex g-05 for replacement from napa.. For history, my prior 2010 6.7 ate water pumps every 60k (and 125k), so I`m not waiting for water on the ground this time around.. Ram will be getting my bill for replacement. (i`m at 53k now)

Wrong antifreeze. You need OAT not HOAT.

I sold my 19 year old 2nd gen this spring with the original water pump. Granted, it only had 150,000 miles but 19 years is a long time for a sealed bearing to last under any conditions. I owned a 2000 prior to the 98 and it went nearly 300k on the original water pump. Neither had a vent hole.

Bean counters win again.

Yea, my 95 didn't have a vent but the older engines ran cooler also. Something is making these bearings fail early on the newer engines. I'm just speculating but we know the bearings are failing. I've never heard of a vent hole before this recall. Could it be that these bearing are just running too hot? The older engines ran 160 to 180 f. 230 f is common on the new engines. Don't know, just trying to figure what has changed.

160? My 98 specified a 190 stat and wasn't uncommon to see 210-215 on a hard grade. My 14 pulling the same loads over the same grades hasnt seen 215 yet. The coldest stat I'm aware of in the pickups was 180, if there was a 160 in the early years it didn't last long for the simple fact diesels don't run efficient cold.

My money is still on cost or poor design, and generally poor design is a result of cutting costs.

I also wonder how much this vent really has to do with the pump being an upgraded part, or if it is more or less being used as a reference by Chrysler to distinguish the two pumps and the pump with a vent also happens to have a better bearing inside.
Would be interesting to find out.

I’m going to make a wild speculative argument here; all the failures are related to Chinese bearings.

Any evidence otherwise?

Additionally.....neither of my replacement Murray Temperature Control water pumps had / have vent holes.....and one went well over 205k miles IIRC.
Actually 230*F, as a rule, is uncommon on any 2013+ truck, unless towing hard. Mine stays at 192*F to 195*F unloaded as a rule, and my fan clutch starts hitting around 215*F to 217*F. I have never seen mine above 221*F.

Let's speculate the hell out of this! If we say certain things enough times, it will become fact! (i.e. the lack of a vent hole being the problem)

So here I sit, continuing to not dwell on this issue, just like I still don't dwell on DEF.

I had the manual transmission and when running empty, my thermostat would open, the temp drop to 160 f, then back up to 180, 190, or whatever the thermostats were. I hated that. The old thermostats didn't have a hole in the flapper and when they opened it was all or nothing. But none the less, I don't get this recall at all. And why 6 months to get replacement thermostats

You may not be too far off. I put brand new bearings (Chinese) on my boat trailer and they lasted about a month.

Yea, you're right. I've only seen 230 one or two times and that was pulling mountain pass in CO.

My sentiments exactly.

I guess we need to get a life, hunh. Too bad FCA would put out more info so there wouldn't be so much speculation. But then these forums would be useless, ha.

mkay... multiple posts from across the net say zerex g05.. ie-- http://www.cumminsforum.com/forum/0...n/426621-what-type-coolant-does-6-7-take.html ... so if that s wrong, what is right?

 

[jhenderson]

Read them closely. 2013 and up use OAT. That would include your 2016, no?

 

[ktfbgb789]

This is what I use on the 2014

You obviously overlooked that the thread you linked was from the 2007.5 through 2009 6.7L Forums.......

To save confusion I just use RAM brand per mixed coolant. The little bit that is needed it's not worth gumming everything up to save a few bucks. Only question that my dealer wasn't sure about was do we use the 5 year 100,000 mile mix or the ten year mix..... Just a head's up... The service guys said that when they do a waterpump under warranty RAM wants them to save and re use the coolant. I'll be demanding a full coolant change when my good replacement recall pump finally shows up. along with a new lower hose.The upper one with the plastic Y fitting already failed.

Same here. Filtering thru cheese cloth or whatever isn't adequate IMO. It's the fine stuff that you can't see that will destroy a bearing, not the big stuff that cheese cloth will catch. This is the opportunity to get a coolant change with no labor.

I doubt it will be no labor if you request a complete coolant change. Not all the coolant comes out when a water pump is replaced????

What bearing comes in contact with antifreeze?
