Hello,
While under the front end today changing out a axel shaft, I noticed a couple drops of anti freeze by the seep hole on the engine water pump. I have not had any problems with the water pump previously. It has 12,000 miles on it, and no squeaks while running.
Is there anything I should be concerned about? Possible pending bearing failure? Or is this nothing to really worry about since the weep hole is there for a reason?
I plan on replacing my alternator in the next few days, and that could be the opportune time to replace the water pump if needed.
Thanks,
Scott

Water coming out the weep hole indicates a bad seal. Might as well do the
pump now if under warranty.

Ok.
Good advice.. going to napa tomorrow to get one. Or any other favorite brands out there??The one I'm replacing is a Tuff-Stuff water pump. Supposedly made in the USA. But only lasted 2 years and 12,000 easy miles...

Get the Cardone Select one. Part # 55-21118H The H on the end of the number is very important. The same number without the H is NOT what you want. Start with Jim K. at Applied GMC. If he is out of stock, then try the others like Rock Auto or Summit. Cardone was selling them direct. They are all about the same price, so go with Jim K. if he has them.
Here is thread on it from about 1.5 years ago:
http://www.gmc.mybirdfeeder.net/GMCforum/index.php?t=tree&goto=341053&rid=12&srch=cardone#page_top
My second recommendation is to throw two cans of water pump lube in the antifreeze when you are done installing the new one. What usually happens on low mileage water pump seal failures is the seal sticks to the shaft when they are parked for extended periods of time. Then on the next start up a piece of seal gets damaged.
A few dollars for 2 cans of water pump lube prevents that. You can get it for $5.00 or $6.00 at your local auto parts store. All it is, is a medium weight oil that mixes well with antifreeze and water. I do not care what brand you get and you do not need all of the other additive crap being sold. Just get the cheap lube.

That's bad news on the Tuff Stuff water pump. I installed that same pump a
year and a half ago on Tom Pryors advice. He found it to be the best
option while developing his electric clutch fan drive back then.
The Cardone model is his current recomendation.
Guess I'd better get busy and find a replacement, JIC.
This is very concerning news. :-\

Waterpumps have been a problem. I installed a cardone Part # 55-21118H one last year, but it seems I bought one of the last remaining. last winter, I think even Jim K could not get his hands on one. Most places would let you order, then back-order it and keep back ordering it. Some claimed some car quest had the re-boxed one, but that was found not consistent over the 50 states.
Dolph was the last one I remember still had a pump on backorder, so I don't know if they ever fixed the ordering. I know a few people have been ordering the milodens. but those are big money.

You would think that slimy slippery ethylene glycol 50/50 would keep the seal lubricated on it's own! Water pump lubricant should really be labeled as "Water pump shaft seal lubricant" as it's not a substitute for the factory bearing grease.

Ken,
No one has the cardone select 55-21118H........ I even call the manufacturer and they said they were not making them any more. Their reasoning was a lack of good cores to remanufacture them.....
My back up plan is a water pump from Napa. Their new pump is part # TFW 43100, their remanufactured part # is WP 58295 H. Both are within $5.00 of each other. Standard rotation on the new pump, clockwise on the reman one.
Any recommendations on what pump to go with? I'm leaning towards the new one..
Thanks, Scott.

I've had good luck with the GMB premium, heavy duty pump I put on my engine when I did the rebuild two + years ago.

Carl,
Did you go with the aluminum GMB water pump?
Looks like have 3 different pumps to offer. OEM with 6 blades on the impeller, Hi performance with 8 blades, and the aluminum one with 8 blades on the impeller. Part #130-1260.
According to the photos on amazon, the hi performance and aluminum pumps are from Japan. MUCH better than the Chinese ones..
Just adding to the confusion!!
Scott.

Scott,
I really don't remember which pump I went with. It was NOT aluminum. I can probably look through my paperwork later and find the part number.

There was talk about trying to identify the part number for the rolled bearing in the “H” cardone pump. Did anyone have success with that? Knowing the bearing number gets us one step closer.

I bought mine off Cardone Select a while back. Called them to confirm the -H was in fact a roller front bearing. I asked about core charge and the guy said they are new construction, not rebuilds. Looked new, too. Howsomever, I had overheat problems on startup with the new engine. Radiator back from the shop, I'm ready to try again.

I spent about 4 hours on the phone with every department in the Cardone menu.. no answers to my questions what so ever, except that they were no longer in production. Very secretive company. They couldn't even tell me who did their ordering. That was odd.
But finally got a hold of a tech that said the best they could do is to send them a core and they would rebuild it. Their rebuilders are in Harlingen Texas, the rebuilders also do the remanufactured water pumps for Napa.
But Carl S mentioned that he was using a GMB water pump. So I did some research on GMB. They are a large conglomeration out of Japan. their production facilities are in Japan, Korea, Taiwan, and China. Seems to be a very respected corporation that is known for their bearings. And they also have the correct bearing configuration (rollers and ball bearings). And they are all new castings!!
So my guess is that the water pump nowadays is like the fan clutch. Seems like Hayden makes all the fan clutches, and rebranded by different brands. So I'm guessing GMB makes all the NEW water pumps, and rebranded by others, including Napa..
What a PITA......
Scott.
