Title: Dodge Cummins water pump...they don't make 'em like they used to
Post by: old head on January 10, 2016, 04:33:57 PM
Wife called and said she had no heat but the truck wasn't running hot.  She was only a mile or so from the house, so I told her to come on in.

Popped the hood and had water pouring out the water pump, rats..  its raining, and it was nasty.

Took her to and picked her up from work for two days, while waiting on the weather to get better.  Cummins wanted 150 for a pump, Dodge was well in excess of 200.  Closest Cummins dealer was about 70 miles away.

got one from the local Federated parts house, 59, with lifetime warranty.

took me like 30 minutes to change it out, never had one this easy, two bolts, nothing to move out of the way, easy to get to, easy peasy.  No gasket to scrape off, just a rubber gasket to insert in the pump housing, grease it up and slid right in.

the kicker, the truck has 298,700 miles and is 22  years old on the original water pump.  Wow, I guess I got my moneys worth out of that pump.

the shaft bearing failed.  was like a weeble woobly once I got it out.

That thing should have gone 300,000 miles. You should demand that the dealer replace it under warranty.

In seriousness - I'm still shopping around for a diesel truck and have been looking at some older models that are smog-exempt in California. Always nice to hear about strong-runners with heaps of miles on them.

That's normally what happens after the seal starts letting coolant into that bearing.   Small Leak > Bearing Fails > Wobbling Shaft > Huge Leak

a friend has a German built luxury car that was 1000 miles from going out of warranty when it's water pump failed so they ate it. I forget the pumps price but the labor was $4,000. because the engine has to be pulled just to replace it. have to love the "better ideas" coming from the car companies today.
he no longer owns it.

200,000 miles on our '95 Volvo 850 turbo's water pump.  Not hard to replace. Did it when I last changed the timing belt.

If only the Dodge trucks were the same quality as the Cummins, but alas it isn't.

Oh well, such is life.

the boss just put me in a new Toyota Tacoma, my old Tacoma had 273k on the odometer.  Other than tires, and brakes, I think I had to fix a catalytic converter (Toyota did step up and warranty it, well past its mileage warranty), and rear wheel bearing went out, that's it.

I retired from Cummins a few decades ago, so it's always good to hear their products continue to meet the customers' needs.  One of my local riding friends was responsible for the initial installation of the 6B Engine in the Dodge pickup.  Through the years they've produced a lot of engines for that application -- probably approaching 2 Million by now. 

Keep driving it.  My bet is the truck gives up before the engine does.

That's an easy bet to make.  I have had spent a ton on ball joints, and AC repairs, and replacing various dash plastic bits.  the dash cracks and breaks just looking at it.  Cheap, cheap, and very cheap.

FYI,  Last time I let a shop put on a "inexpensive" water pump the bearings went out just after the 1 year warranty.   I always request OEM.  They charge you the OEM list price and put on a $9.95 import. (yes, I saw his cost around his computer screen)

I sold Dodges for awhile and a frequent comment on trade ins was, I wish the rest of the truck would last as long as the engine.

I would have put on a Cummins part if there was a dealer close by, didn't want to drive 76 miles or have one shipped, the truck is driven everyday.  Had Dodge not marked the part up so much I would have gotten from them, but geez, they are proud of their handling.

So, as easy as it was to change it out, won't mind going back in there.  I do prefer OEM on sensors and such as that.  But have had pretty good luck with this brand's quality.  Only time will tell.

Sounds like a Porsche 928 that lost its water pump.  I understand they are monsters to replace.

Mine's had nothing go wrong, no plastic bits breaking, nothing.  There was a recall on the ball joints.  FWIW, the Tundra I had also had a recall on ball joints and it had a transmission problem at 80k miles.

Every December I shake the bell for Salvation Army at our local Rural King store.  RK is a farm type store with a very wide inventory and, of course, a wide variety of customers.  Shaking the bell is a fun gig and I meet a lot of interesting people.

Where I stand to shake the bell I can see/hear everything that drives into the parking lot.  Last year a Dodge pickup drove in and it sounded "funny", not like a normal gas engine nor like the 6B diesel.  When the driver and a couple of kids came to the front door I asked him what was different about it.  He said his pickup had a four-cylinder Cummins diesel engine.

Cummins produces the B Series engines in both 4 and 6 cylinder versions for customers other than Dodge.  Case, for example, uses those engines exclusively in their farm equipment.  Cummins produces the engines for the Dodge pickups (only the 6B version) at a plant just south of Columbus, IN.  They produce engines for the other contracts at several other plants scattered around the world.

This pickup driver had taken a used 4B engine from another application and installed/converted it for use in his pickup truck.  He said that although it sounded a bit different, it performed very well and gave him very good fuel mileage.

All for now.  Ride safe out there.

I have owned three.  Great engine.  The truck so-so.  Ball joints on every one, transmission issues on one.  Poor dealer backup.  I moved to GM diesels and am way happier.  The Allison trans is the deal breaker over the Cummins engine.  I plow, tow and put 40K mi per year w/o any issues.  I would be lost w/o it.  8 below right now.

I have a `89 Dodge 3/4T PU and the water pump is still good, but last year I had to replace the radiator and now the top radiator hose!   Some of the plastic trim in the cab is breaking up, dang POSs.  :sad:  Original owner  58K miles on it.

That GM Duramax is actually an Isuzu.

That GM Duramax is actually an Isuzu.

It's actually a Duramax.  A GM-Isuzu partnership and its own company. 

"The 6.6-liter Duramax is produced by DMAX, a joint venture between GM and Isuzu in Moraine, Ohio. The Duramax block and heads are poured at The Defiance GM Powertrain foundry in Defiance, Ohio. "

Yes, it's an Isuzu design.  I also own a Isuzu Trooper it's well made, trouble free and durable.

The Duramax/Allison has been a pretty reliable engine compared to the various Fords and Cummins since '01.  But my particular model does have known issue with water pump replacements (I've not encountered it but I do expect it).

I heard that Piaggio was working on a MG diesel v-twin. That one might have a bigger torque reaction at idle more than a gas version IMHO. :rolleyes:

 Considering the Diesel option is about 7000 bucks on a new truck, you might just think it's a bit more quality...

So, (see, I started a sentence that way) the Duramax was designed by Isuzu, hence it is an Isuzu engine.
A friend's son bought one the first year they came out. It was in the shop with engine trouble so much he traded it before it was a year old. Took a bath on it.

Mine wasn't even broken in until it passed 50k miles  :)  Went from 15-17mpg to 17-20mpg.  If I am running slow on the highway (60-65) it will get over 20mpg.

30 years ago, before diesels in pickups were as common and as good as they are now, the two engines to have were the Chevrolet 454 and Ford 460.  Luckily, the speed limit was only 55.  They weren't that powerful and they returned horrible fuel economy.

It was not real common, but back then people did put commercial diesels into their 1-ton pick ups to pull horse trailers.  They were always head-turners, and it was interesting to talk to the owners about the conversions.  Lots more power and economy.  Plus they looked and sounded cool.

My  '93 Chevy 3/4 ton was the best truck I'd ever owned.  6.5L diesel.  Wore out that engine after many years and put a new mil. surplus upgraded 6.5 in it.  GM overhauled trans., aftermarket free flowing exhaust, header thermo wrap, mandrel bent exh. crossover, better turbo and an intercooler.  One of my boys always says,"Dad, why don't you get a newer truck with the 6.6 Duramax".  Yeah, I guess that's a good engine.  But I've found GM pushrod iron block V-8's to be about as reliable as any machine I've ever owned.  Good truck and I'm keeping it.  Only thing I did wrong was rebuild the entire suspension with polyurethane bushings.  Bad idea.  The ride was so rough I had to remove at least the poly mounts between the cab and frame and put in new GM rubber mounts.  Felt like I was going down the road on the rims.  Just a word to the wise to any old truck owners here who are thinking about a suspension overhaul.  Stay away from polyurethane.  Just my .02.

Well, the aftermarket pump lasted three days  :sad: :sad: :sad:
three gallons of anitfreeze wasted, wife not happy, and me having to to the same job twice.

drove to Morgan City to get a genuine Cummins pump.  so far no leaks.

called around BR to dealers that are Cummins dealers, but one wouldn't take the time because it was going in a pickup.

Couple others said they didn't stock it.

One GM pushrod V8 to stay away from (if any even exist any more) is the early 80s 350 Diesel.

My replacement water pump is still going strong after a year - I believe I got it online at Rock Auto with a discount and they had 3 different manufacturers under several brand names and the price spread is big. I got the water pump that looked the best at the lowest price or bought the one that was the most popular.

It is very simple.

How did the new one fail? Water leak past the thick rubber gasket? Bearing failure on new pump?

The hardest part is replacing the old belt and dealing with the tension pulley arm, while reinstalling the new belt.

Diesel-Smiesel,  my #2 son's 97 Ford F150 gasser has 285,000 miles with the same water pump and it spent the first 13 years as a Construction Company truck being throughly abused, then a High Schooler's transportation, then 4 years down in 29 Stumps ferrying Marines to Vegas, San Diego, LA while being left in desert for many months.

My brother had a late 90's Dodge Diesel 3/4 that we sold because the tranny bad after 275,000 and other than the engine truck was generally falling apart.

People just have to learn to do some of the maintenance themselves (like with Guzzi).  If you rely on a shop you'll be trading them early because you get tired of paying shop rates for maintenance.

That being said, I just got through replacing the #2's Ford headlight-turn signal assemblies, last year I put a new starter, battery, radiator, rebuilt fuel injectors, new gas tank filler hose, new Tranny filter and new dash lights in it
