water pump replacement

Where does everyone buy their replacement water pumps at?

I know local auto parts houses are apparently a bad idea, so I assume OEM is the best bet. Do you guys use your local dealerships? or order online somewhere?

I'm @ 125k, and my Jeep was seen weeping yesterday...so I figure I'd better swap water pumps.

As of lately I've been ordering stuff from RockAuto.com, both for my truck and Jeep.

We don't have any local dealership parts. My mechanic goes for guaranteed aftermarket, usually Napa, Bond Auto (local group) or even Autozone because they will test anything first. Dealership is last option for something you can't find anywhere else. Quadratek, 4x4 Offroad, etc. all sell quality parts and back them up. Dealerships get top dollar, won't dicker with you, never have it on hand, so why bother? Get a good relationship going with your own local parts house and it will be worth it at some point when you are in a jam-they will even loan or rent you tools-dealership won't do that!

Yeah Rock auto has a Gates branded Water pump. Gates used to be good...but its been a few years since I've had to do a water pump.

When I was a mechanic we got most of our parts from carquest/ Napa. a water pump is one that I do not want to have to redo, so I'm specifically hoping for first hand experience. The "lifetime warranties" don't pay me for my time when they go out prematurely, I don't put a lot of faith in those.

BUMP

Went to NAPA, the part number they have listed (and I pull from their site) is 42293 - which shows to be a standard rotation pump.

The refurb that they list for the TJ is bringing up as a counter clockwise rotating pump (which would be correct).

Has anyone tried to but a NAPA pump and had such an issue? I was trying to avoid refurbished....but my options are shrinking.

Well I went with a NAPA branded new pump. On their website, and in the store it says its a standard rotation pump (it is not, thank god).

I went ahead and replaced the T-stat, belt, all 4 hoses while I was at it.

Make sure you have a good scraper to get all the old gasket material off the engine block.

Everything is back together and running (no leaks so far knock on wood).

If you use the 4x4xplor.com writeup and don't have a fan clutch wrench, don't waste your time trying to find one the right size...just use a large crescent wrench. (I bought a 15'' one at harbor freight after trying two different auto parts houses "rentals"...and having 5 different sizes to choose from, all of which were wrong).

also, I took the four bolts off the water pump pulley before I removed the serp belt. and finished tightening them after I had everything else together.

now after doing that, I found another jeep identical to mine, but with an Automatic, I'm going to try to make a deal to swap for it, but I have a feeling the dealer that has it won't work with me enough for it to be worthwhile.

That's not true, except perhaps at your dealership. My own local dealership started providing parts to me wholesale simply because I took the time to become friends with several including the parts dept. manager, or at least become known by the other parts counter people by simply being friendly and taking the time to sit around and BS with them a little when they weren't busy. That didn't take any real effort or time either. After a short while, I didn't even have to ask for a discount. I had similar experiences with a whole bunch of my local Jeep dealerships in my local area, I don't recall any of them refusing to discount the part if I simply asked them too.

And while they can't stock all parts for Jeeps, they darned sure stock more commonly used OE parts like water pumps etc. than the local auto parts stores do.

Personally, I won't buy things like water pumps anywhere else unless I am convinced it is the OE part. Too many junk aftermarket parts from China. I use aftermarket parts all over my Jeep but not things like sensors, water pumps, starters, alternators etc.. 90% of such stuff sold by Autozone, Kragen, etc. is junk.

As requested, here is a picture of the OEM pump's impeller (I don't know if that's the proper term, but its what I'm going to call it.)

The vanes are pointed the same way as my thumb if its not visible.

This is important to those who are unaware.

Based on my research all water pumps are made in China. so I went with a distributor that I trust....and took my chances.

You are incorrect. Not all the reverse flow pumps are marked with an R.

The ONLY way to tell is to look at the impeller, and make sure they are facing the same way as the original.

Glad you can accept that.

There is actually a thread on this subject at another forum, that supports my position. as multiple people have encountered this issue over the years (as you'd imagine).

Yeah I have pretty much decided after reading the different threads to just get one locally at NAPA so I can physically verify it. I would hate to order one online and find out it was wrong. Besides the online ones are only about 10bucks cheaper, and I know my local NAPA will stand behind it if something happens.

This was the theory I went with as well. Back when I was wrenching, we got most of our parts from Napa. (I was a suspension/brake mechanic). even their rebuilt stuff held up, and we never had to re-do a job. so that was encouraging.

The guys at Napa stores in my area are great to deal with. They had no problem ordering a new and refurb. pump for me, so I could compare (I bought all the parts before I took the Jeep apart, so I wanted to be able to compare the supposed clockwise pump with the refurb "counterclockwise pump".)

I bought all 4 hoses, coolant, thermostat, gasket, serp belt, and water pump for what the dealer wanted for just the pump. so I'm pleased.

I think I posted it before - but -

The difference is the DIRECTION the pump turns. A V-belt turns the pump one way, a Serp belt turns it the other way.
The impellers are different, the castings are the same.
They first went to serp belts, around 1989 on some vehicles (I have an 89 Cherokee with the serp belt,) but some Wranglers didn't go serp untill a few years later. The first factory pumps had "REV" or "R" or "REVERSE" stamped on the housing, indicating it had the serp type impeller. But the later ones don't! That's what started the confusion.

Since then rebuilders got hold of them, that's why some rebuilts still have the "REV" on them. But - some of the "rebuilders are not aware of the difference. When they disassemble it to rebuild it, all the parts go into a pile. When they reassemble them, impellers get mixed up. YOU CANNOT ASSUME THE "REV" STAMPED ON IT IS TRUE.
The only way is to match it up with the one you took off - IF it was working fine before.

Pumps more recently built may or may not have the "REV." Parts houses have assumed all the pumps are the same, so they have combined numbers - many don't show "rev" or standard rotation. -- Which would YOU call "standard rotation" - early or late pumps?
My Rubi - still with the original factory pump does not show "REV", yet it's a serp belt.

In my case, I bought a '90 Cherokee with a cracked head (4.0, serp belt) - the PO had overheated it. It looked like the pump had been replaced very recently. The radiator was also badly plugged. I put in a new radiator along with a new head. But - it still very quickly overheated, even at idle.
So - the real question now is - could it be he replaced the pump with the wrong one? I haven't had a chance to check the flow yet.

Carcrazy - could you post a pic of the back side of your old pump and post a picture of the installed pump showing the belt - and the direction it turns? Telling us the year and engine in the same post would also help. We know yours was cooling fine before you replaced it - those pics will show what works. It will be a great help to stop all the confusion.

Searching the web there is almost as much wrong information as right information - so your pictures will be of great help to everyone.
