Stock water pump?

Colt · 08-26-2013, 03:08 PM

I'm close to 43k still on original I believe. It's always in the back of my head when it's going to happen.

Are you feeling lucky?

For 2008's its looking like a 50% failure rate on the water pumps.

Would highway vs city driving make any difference at all regarding pump failure?

I don't know, but I suepect it would make no difference since the pump is electric.

Thanks, Dack. You always know how to brighten up the room with your presence

I'll probably be voting/posting in that thread soon I feel

Darn, I was hoping my highway miles will buy me some time. I am almost at 40k miles. If you preventatively change the pump, when would you recommend it? And what else would you get done when things are apart?

By looking at my water pump failure poll... I think for 2008's and 2009's - I would change the pump before 60K miles. I would also change the thermostat as well.

For 2010's (& up)I think I would wait until 80K ish. Probably at 80 or 90K I would also think about changing the radiator as well as the upper and lower radiator hoses.

Thanks Dack. I will put that on the back burner for another 20k miles!

mine just went out on me @ 48k a couple weeks ago right before a long driving trip...lucky i limped back home which was a few blocks away when it happened.

Are you going by the poll, or another source? I only ask because the numbers in the poll show about a 31% failure rate. Not trying to be inflammatory...I'm just curious.

BMW cooling systems generally fail at 100k, most in the know change them at 80k, so yes, 108k is a crazy thing to do.

I plan on changing mine every 40k at half intervals to the rest of the cooling system.

I'm at 127,000-ish with an '09. I know I'm on borrowed time, but I'm still running strong on the original. Most of the miles are highway and I live in CT so the winters and summers are both brutal.

Think I'm going to change mine out when this current smoke issue I have with the engine gets resolved. Do you recommend genuine BMW or a VDO water pump? It seems kind of idiotic to replace the water pump with the same piece of crap....why doesn't a 3rd party make a better water pump by now?

Yes, just going off my informal unscientific poll.

For 2008 M.Y. cars the failure rate is at 45% in that poll. (38 failed vs 84 still ok). But also bear in mind quite a few guys had voted "ok" and then their pumps failed. So... take that poll with a grain of salt. It just gives us a "rough" idea on the failure rates.

Like I said IF you don't want to be stuck broken down somewhere... I would replace your pump at 60K to 80K miles max. IF you are feeling lucky... keep rolling the dice.

I believe the water pump that BMW now sells thru the parts dept is of a different supplier than the early(2008/09) cars came fitted with.

Personally, I would have no trouble using a BMW dealer bought pump. And besides when you buy from a BMW dealer the part comes with a two year unlimited mile warranty. I wonder what the warranty is on the aftermarket pumps?

I learned a long time ago that when it comes to water pumps(thermostats and radiator hoses) and brake rotors... only go with BMW dealer parts. For some of the other stuff like radiators, fans, filters - its ok to use OEM instead of OE(BMW) parts.

Good Luck,
Dackel

Actually, your math is a bit off.

38 out of 122 (38 + 84) is about 31%

However, 1 out of 3 failure in 5 years is still high IMO.

quite a few of those answers changed but couldn't be changed in the poll. Dackel isn't kidding about the 50%-ish.

Ohh yes, I see now. I was using 84 as the total number. Still it is a high failure rate and scares the crap out of me.
