Possible to identify waterpump date?

I have a 335is I bought at 55k miles now at 62k miles.

I'm unsure if it's been changed before. Is it possible to see a sticker of PN or date produced or something without having to remove the pump?

Yes, is printed on the metal side of the pump. Towards the front. Where that ground cable runs to the engine block.

Is pointless. You will find out nothing. Pump can fail at any given time. Failures aren't associated with neither time nor mileage.

Ah really?

I see a lot of comments saying they last around 60k miles.

But I did see some last much longer but the overall feel I get reading is that 60k miles is the usual?

Ok, and have you read my comments that I'm @ 102k and replace the pump twice already?

Mostly depends on how vehicle is driven, then climate, then age and mileage....

As I said, it would be pointless. Don't waste thought let alone time getting under the car.

Alright, I guess I'll look out of curiosity next time I'm doing work under there.

Hoping it wouldn't go out in the middle of winter, worst time to work underneath.

Thanks!
