Who makes the 2003 water pump?

[Sasha Maccion]

Does anyone know who makes the water pump on my 2003 Sport model? Looking to replace it or upgrade if there is something better. Thanks in advance for any replies.

One thing to keep in mind, from my experience...bought timing kit to replace for my 04 v8, feom Napa, waterpump was absolute crap, definitely would go to toyota for sonething like that next time.

While NAPA may sell crap water pumps for the 4runner...that doesn't mean there aren't GOOD QUALITY aftermarket pumps out there. TRW makes excellent water pumps. See if they make one for the 4runner. I rarely ever buy anything from NAPA or any national parts chain. We have a few local parts store chains that carry quality parts. Most of the good mechanics buy from them. They don't want to deal with cheap parts from the chains because they warranty their work.
