Water Pump Weep

Hey Guys,

 

Ok so almost 2 years to the day my Water pump appears to be weeping out the weep hole.

See thread here where I changed it out:

http://www.gm-trucks.com/forums/index.php?...c=72209&hl=

 

However, now it's weeping again and oddly enough today, I only noticed it do it when the Block heater is plugged in. I'm going to leave the Block Heater unplugged for a week to see if it does again but, I'm pretty sure it's completely coincidental to the Heater being plugged in.

 

I'm surprised as heck that the water pump has failed after such a short life but, maybe it was a bad unit. It wasn't a true "GM" water pump it was a replacement one from Lordco.

Perhaps I should pony up and get the correct one from the dealer...

 

Anybody have any thoughts on this?

All my mechanic friends tell me to never buy a re-furbed pump or alternator or other crap, and to always get new. ??? I went thru 3 re-built autolite alternators once within 2 weeks on an old 89 Jeep Wrangler before I took it into my mechanic, all he did was take out the POS rebuilt and put in an a brand new AC/DELCO, never had a problem after that :crackup:

Guys, there is nothing wrong with rebuilt alternators or water pumps. It all depends who rebuilds them and how. A properly rebuilt alternator will have all its internal parts replaced, all they reuse is the outer housing. This what you buy for example from a Nissan or Mazda dealer. On the other hand, one from Autozone or Advance Discount will have only the front bearing and the voltage regulator replaced, and that's it. So if something else like diodes or the stator windings fails, the alternator will go bad in a very short time.

 

The same goes for waterpumps. If the housing is in good shape, all they need to replace is the bearing, seal, and the impeller.

However, cheap rebuild shops in Mexico may not replace anything but the seal, and maybe even press it in wrong. And that is the type of rebuilt water pump that comes in a nice shiny box at Autozone for $ 9.95. Discount auto parts stores typically buy rebuilt parts from the lowest bidder and abandon them when they have too many returns. It is ultimately the customer that gets frustrated with crappy parts that have a "lifetime" of a few weeks.

My water pump is going out on my '96, and I decided to go with a new True-Flow pump from Napa, they have a lifetime warranty on them, and appear to be pretty good quality, and the salesman I talked to and know personally said that they have had no trouble with them, and that's what he reccomended

      Gas Prices

      By Chuck FB · Posted

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.

      Correct.  2019-2021 model years are serviced by a different p/n.  19420611.  Recall 2021s use 19420611.   The recall engines 2022-2024 model years are serviced with 12740076.     The difference between 19420611 and 12740076 is GM changed injector size for 2022.  The injectors are smaller on 12740076 with smaller injector bores in the cylinder heads to match the smaller injectors.  So you can't install a 19420611 in a 2022-2024, and you can't install a 12740076 in a 2019-2021.     Both engines are the replacement engine p/ns that are in the L87 recall.  So both of these are the updated engines.     Here's a version of the L87 recall with the p/ns for all the parts needed.    RCRIT-25V274-7075.pdf   Note it shows 19420611 and 12740076 with an asterisk to a footnote "Use the VIN and the GM Electronic Parts Catalog (EPC) to determine which part to order if two or more part numbers are listed for the same part, as it may vary by vehicle options."

      2020 Trailboss 6.2 replacement

      Looking for advice from this group. Took my flawless 2020 6.2 TB to an unnamed shop for routine rear brakes and oil change. Tech forgot to put oil back in after the full service and needles to say, destroyed my engine.  It’s all on their shop video so they are responsible.   I had my Chevy dealer do the analysis and they confirmed its compromised and said engine replacement. The manager said they only get GM reman engines from GM with full 3 yr warranty and the one they would put in is not same as what’s they are swapping out on 21-25 for recall.    I am looking for advice why that would be a different engine because obviously I had the good 6.2 year and replacing it has my concerns with that recall for 21-15   Also what’s the pros and cons of accepting the engine swap vs telling the shop that bricked the truck to pay up so I buy a new truck. I’m concerned about stigma resale eventually if I just decide to get rid of it after the swap or other issues showing up after the swap out.

      AFM Disabler Question

      By GN2018 · Posted

      Just looked up my records.  I've never gone over 5000 miles between oil changes.  At 46K miles, I have 10 oil changes.  I hope that will help.  I also installed the disabler last year.  I've still had a few times when it didn't seem to engage (which I can tell because the start stop feature kicks in), but for the most part, I think it's working.  For some reason, GM did not include the number of cylinders running in the information screen like I had on other models.  In my Cadillac, it shows me when it's running on 4 cylinders on the fuel milage screen.  I can't find that on my '21 Denali.
