Water Pump Advice

[PlayingWithTBI]

I bought the Tuff Stuff 1675A high volume water pump over 4 years ago. While dismantling the engine for a new short block I noticed it's seeping a little out the weep hole already.

I’ve been using Peak ready to use.

Is the water pump supposed to spin this easy? Could have sworn it always had more resistance. And it's got a funny eerr sound...little pooter..when first spinning...
Just curious....It's only a couple of months old.... here's a couple of videos....
I guess it obviously has more resistance without the fan on but it's more of a sticky resistance like the mounting flange is getting crusty...idk
My overflow tank hasn't been acting like I'm used to. Doesn't seem to do anything... but temps are registering fine and thermostat kicks in fine.....
seems like I should replace it regardless...??

You're paying too much. Premixed "50/50" anti-freeze is half water, and distilled water is about a buck a gallon.

WHICH "Peak" anti-freeze? They've got several formulations.

How much freeze protection do you have? Actual 50/50 concentration should be about -36F, or about -37C.

There's some visible rust-spots on the impeller. Were they there when the pump came out of the box it shipped in? Maybe it's from being packaged with humid air, and sitting on a shelf for two years.

"Looks" fine to me. There's going to be some bearing drag, and some seal drag.

Is that the CORRECT fan clutch? Did you install a Heavy-Duty or Severe-Duty clutch on an application that calls for a Standard-duty clutch? I wouldn't expect a fan that small to be driven by a clutch that big.

My overflow tank hasn't been acting like I'm used to. Doesn't seem to do anything.

Verify coolant level in radiator and overflow bottle, and check the rad cap.

I don't know. It's original to the truck when I got it. I remember replacing the clutch maybe 7 years ago with whatever parts store gave me for my year make and model so I guess it's what's supposed to be on it.

All levels are good. Do have a replacement cap that was put on several months ago... Motorad I think. I used to be able to shut the truck off and see all kinds of action in the overflow. Now nothing happens.
If I slightly loosen the radiator cap while hot ..slightly.... it'll release into the overflow...start bubbling at least....
I'll investigate more....

The sounds are weird.....sounds like a baby animal of some kind.

 

[Schurkey]

A baby seal, no doubt. A rubber seal on the radiator cap, but a baby rubber seal.

Pitched down clown horn...speaking of clowns, the fan clutch has tension when the belt is attached to the pulley. That's what I was remembering...lol

Many of them come just raw cast iron with no paint at all, and you paint it yourself. It's not a piece of styling; it's a functional engine component.

Last one I bought for a gmt400 came from Carquest right before Advance bought them out. Carquest branded box, new/not rebuilt. Got it to replace a NAPA branded new/not rebuilt that had failed with a bearing squeal, got replaced under warranty, and brand new one squealed right out of the box.

Sounds familiar from nearly 20 years ago.. battling the water pump on that gold '93 I'd built for an ex.

I think the Duralast I replaced with this one under warranty was about 1 year old. The bearing was binding up a bit in a certain spot. I wouldn't have noticed had I not been getting at my balancer.
