I have zero exp with any of them. I just did replace mine though. Couldnt find the Mopar anywhere near that price you quoted- couldnt buy from walmart online.
Besides -i researched long and hard ( for me anyways ) and what little info I found stated that the Mopar had a plastic impeller. So I ended up going down to my local NAPA and got the NAPA one. Made in the USA, Lifetime warranty, metal impeller, $35-- I had to go with it. You might want to take that into consideration-- just sayin

 

the Mopar had a plastic impeller

Interesting, my first thought was, if doing all this work, then why not Flowkooler?

But your reminder about the plastic impeller makes me wonder if it was intended to reduce corrosion? Maybe corrosion is no longer a concern because of the 5-year coolants?

 

Seems like most Gates pumps I've put on cars have leaked prematurely. We don't even use them in our shop anymore unless that's all we can get. Sucks, because they're supposed to be made in the USA. I can't afford comebacks, so... As far as GMB goes, it's about the same story. I'd rather spend the money on something good than have to do the job twice.

 

My experience recently was that a orielly rebuilt with 5yr warranty failed at 11 miles. I did not have time to redo myself, so I sent to a reputable shop who said "never do rebuilt", new is fine but no rebuilts of any kind. He did put in a Mopar at my request and I have been happy, only have about 500 miles since, but all good. I'll go for reliability over warranty and cost anytime.

Just a few pennies out there.

 

Replaced my engine a couple months ago. Installed a new Napa pump with it. The new napa pump I got had a plastic impeller.

 

I guess I'll go with Mopar and not take any chances. The pic shows it with a metal impeller. Thanks guys.

 

I installed a MOPAR pump a few months ago. Purchased from WeRMopar. It has a plastic impeller. Strange that your pic shows a metal one.

 

A bit late to the party, but I had an AC Delco pump last nearly 8 years (~55-60K miles), that was replaced just over two years ago with a Gates pump. I hope I have better luck with it than is suggested by Arty McGeep.

I just installed an AC Delco, made in china. The impeller is metal on this one. Seems well made.
I might never find out since I drive about 20 miles per year.

Jonny Jeep had good luck with his.

 

Keep us updated on the impeller. All the Mopar pumps I've bought previously for 4.0L engines have been metal. I do know that the 3.7L in the Liberty had a plastic impeller. With that said I've only bought Mopar pumps. Twice I went with something else (Duralast and Advance auto) and regretted it soon after.

 

I’ve had two Gates pump start leaking after a couple of years. Went with Mopar this time. It should arrive this Thursday. I shopped all around and ended up paying $158 with shipping. Where can you get it for $75?!

Ebay from a Mopar dealer.

 

I think the earlier year TJ's had a steel impeller whereas the later ones had a plastic impeller. dont know the cut off date but I think the difference was when the fan clutch was changed to a single large nut attachment from a bolt on arrangement.


replaced mine about 100,000 kilometers (62,000 miles) ago with a genuine Mopar pump. still going strong and it had a plastic impeller

Interesting. Mine is an '06.

 

I was wrong about the plastic "upgrade". My Mopar water pump just showed up and has a metal impeller and came with a new gasket. It looks just like the pic I posted on #7.

 

 

I'm still trying to figure out why the Mopar TJ pump lists for more than twice the price of the XJ one. Supply and demand I guess. :dunno:

 

I have had an Oreilys (Lifetime warranty ones if available) on my 1979 K39 since about 2009, my TJ since about 2017 and my XJ for a couple months.

None have had any issues.

 

I wouldn't care plastic or metal, but the design of the impeller with that backing plate seems to be the main difference between regular pumps and flowkooler pumps (which is what I have run for 15 years with no issue).

 

This is good to read. My flowkooler pump has been installed for about 3 years with no problems. Hopefully, it will last at least as long as above.
My engine generally runs hot due to the intercooler in front of the radiator, which is why I got the flowkooler in the first place. By the way, I did not notice any difference in the cooling performance between the stock (working) pump I replaced and the flowkooler. Clearly that wasn't the problem.

 

A few years ago I needed to replace the water pump on my '04 I6. Every one I looked at had the plastic impeller, with which I was not comfortable.

Happily, I was able to find a suitable replacement with a steel impeller:

..and to make it work I only had to replace one other part:

Did that other part come included with the new water pump or did it cost extra? :drool::thumbsup:

 

I put a Mopar pump in our 98 ZJ 4.0 back in 2010 and it’s still working fine now.

 

gmb is very popular in the import car parts market.
particularly european imports.

The factory original Mopar part from 2003 had a plastic impeller. It looks great after 17 years and 175k miles, but the bearings finally failed.

 

last summer i bought a mopar water pump, upper and lower rad hoses, serp belt, t stat and gasket,
idler, tensioner, and both power steering hoses from a local dealer, it was all in stock, and much cheaper than i expected!
all in mopar branded packaging.

 

The seal on my pump leaked last year, forcing a replacement at 13 years. The plastic impeller looked pristine. I did a little destructive testing on it, and I can now say that I trust the plastic impeller completely. It's fiberglass reinforced plastic, I had a difficult time breaking it with a pry bar and a sledge hammer. The shape is much more efficient than the bent steel one, so it will give better performance than the metal one.

 

I trust the Mopar brand. Only time will tell. Prices were so good that I bought one for the XJ too. $57.
