97 5.7 water pump
Well the water pump on my 97 with the 5.7 is leaking again. This will be the third one since new. Looking at the Rockauto site and there are a lot of options.
ACDELCO 252711 Gold / Professional is $39 and ACDELCO 251719 GM Original Equipment is $150 Is one really $110 better? Any recommendations on water pumps? Thanks Paul

Re: 97 5.7 water pump
I'm a Gates man when it comes to cooling system parts. In 30 years of doing it professionally and semi professionally I can't remember a time they've been a disappointment.
Throw a fan clutch at it too to make sure your pump lives a nice long life.

Thanks Kevin Rock shows fan clutches from $29 SKP brand to $100 Genuine GM. Any thoughts there? Other brands are Hayden and Four Seasons. Nothing listed for ACDelco for trucks with AC. Paul

I went over to Rockauto and ran your truck through the lookup. If it were me I'd choose the Hayden 2786 for 37 dollars. Be sure and use a discount code any time you order from Rockauto !

Re: 97 5.7 water pump
Let us know how the $40 water pump goes. I have the original cast iron water pump that came with my truck in 1998. I'm not going to buy a cheap ass water pump. Sorry.

Re: 97 5.7 water pump
I use the lifetime warranty Auto Zone water pumps. No problems as long as I don't let the coolant run low.

Second, I will tell you having been on both sides of the counter at auto parts stores. They will only give a person a set number of free parts and then turn the customer away. Now I nor anyone else can tell you what that number is. It will depend on many factors. But no one will get unlimited free replacements. When I had a mower shop, the worst competitive crap made, had the best warranty. A good warranty does not mean you are getting good product. Last what good is a lifetime warranty if you are either constantly changing the part or worse, stranded? |

Re: 97 5.7 water pump
Warranty means nothing to me on most auto parts.
If a water pump fails it's liable to puke 20 dollars worth of antifreeze onto the ground, possibly cause an overheat and ensuing engine damage, possibly damage my fan shroud and/or radiator. It also causes me stress and inconvenience. I ain't got time for that. The Gates pump I recommended is a good one. I just put one on my own truck a few weeks ago. I try to stick to Gates for most all of my cooling system parts including hoses and thermostats. I've been using Gates, Dayco, Hayden, etc for many years. They've proven themselves reliable.

A few weeks ago I was under my own truck doing some suspension work. I like to lay there with my flashlight and just look around. I do this periodically. This time I look up and notice a drip hanging off my lower radiator hose. Closer look reveals the water pump is leaking out the weep hole. No big deal, I go in the house and Rockauto a new pump and a new lower hose for good measure. Ain't no big deal. I do love catching issues before they become a problem anyway. This is a new-to-me truck so I'm still catching up on stuff that needs attention. The new pump gets here and I install it and the hose. No issues whatsoever. I'm actually humming and enjoying the process. I do love fixing trucks. Then I reach over and grab the fan to install it and something sticky gets on my fingers. What the hell ? Fan clutch leaking. I hadn't noticed that before. Then i really look close and when I rock it forcefully, there is a lot of play in the clutch. A lot ! What's the point ? I nearly missed it and the fan clutch was guaranteed the reason the water pump failed to start with. That's a lot of mass mounted on the snout of that water pump and when it spins wobbly, the bearings stand no chance of enduring it for very long.

Re: 97 5.7 water pump
I remember when water pumps weren't a fail item. First original pump on my '89 didn't last long at all. In '94 on my third engine that I installed myself at the curb outside my apt. at the time I went with an Edelbrock water pump that was still going strong when I replaced that engine twenty years later at 190K with a fresher engine. I'll stick with the Edelbrock pumps since I feel the ACDelco parts don't have the dependability they once had.

Mechanical items fail. I'm w/Tx Firefighter on the clutch-fan inspection if someone has a failure they think 'should not' have happened.

Re: 97 5.7 water pump
Thoughts on a fan that is slightly bent? Could that be the reason I've gone through 3 water pumps on my truck?
I'm looking for a replacement already. I didn't notice the bend when until after I sandblasted and painted the old one!

Sounds like you found the root of the problem.

Re: 97 5.7 water pump
Well now the problem is matching up the fan with a replacement. NAPA shows two different fans. A metal 5 blade for trucks without AC and a plastic 11 blade fan for with AC. My truck has AC and it has a 5 blade metal fan that is about 19.5" across. The metal replacement fan says it is 18" across.
The listings on Rockauto and Advance show similar results. https://www.napaonline.com/en/search...onEnabled=true

Re: 97 5.7 water pump
That's what I was thinking but why the heck does my truck have this 19" metal fan in it? I bought this truck new so I know it hasn't been replaced!

Re: 97 5.7 water pump
Might have been what was available from suppliers @ that time. My buddy told me they'll have different parts suppliers sometimes for the L/R versions of some parts strictly because one supplier beats another on costs for that particular item.
