Water pump OEM Toyota or GRAF

Electric water pump is leaking, replace with an oem toyota part dont cheap out and go aftermarket on this part.

If it *is* leaking you might want to consider replacing it with a Graf alloy-bodied pump which won’t be affected by heat and exposure to oil, the usual causes of eventual failure of the plastic pumps.

Graf has been pretty good to me.

I have the Graf brand on mine, replaced mine at around 120k miles. It’s aluminum and has aluminum impeller also.

I installed one on me 325i 12k miles ago, no issues so far, it was part of the FCP euro water pump kits

6 months and 4000km on mine. Only found out a while after Graf has a bad rep. But no problems with mine yet.

I've also had a Graf I think it was, it did have a metal impeller, which started leaking after 7 yrs.

My water pump was leaking this Fall at 235k. New mechanic showed me the leaky pump and it was oem toyota.

Have had bad luck with graf metal impeller pumps, multiple failures over 2 different cars.

Well, all of these seals are not created equal in my experience. I have had a bad experience with some seal kits that had combustion chamber seals that were really hard so they didn't stretch evenly over the injector or compress properly with the proper tools. Luckily I was able to source some of the correct ones from a tech friend the same day, so I was able to get my car going. You really need to make sure that you have the right ones, as you have to destroy the old ones to remove them, and if the new ones aren't right, you are screwed. I personally won't recommend anything other than factory parts, as too many times I have tried something else, like Graf aluminum water pumps (two failures-100%, within six months) and gotten burned.
