Water pump OEM Toyota or Hepu

I wish I knew myself before my overheating probs with the failed first gen water pumps from toyota. Once the new pump was in the engine would work really well when it comes to heating and cooling.

My original lasted 18 years / 249k miles. The replacement one has been in place for almost 2 years / 22k miles.

My 99 V6 just rolled 316k, am looking into my 2nd timing belt/water pump DIY

Graf & Hepu brand water pumps are both metal impeller high quality oem suppliers

Engine water pump is leaking coolant. The pulley and drive belt are slinging the coolant onto other components. Highly recommend to replace with factory parts.

Mine started going out at ~165k in 2023. 05 Prius. I mostly drive less 5miles at a shot, and it would toss a code if driven much more than that and it was hot

My Tundra was awesome, but guzzled fuel and I drive like an old grandpa. 13-14 mpg is expected. Also, Tundras are fairly expensive to maintain compared to Ford. My water pump went out and it was about $1k to get fixed.

I am dealing with a similar issue right now on my CJAA which I changed the timing belt in April this year. Leaking from same spot. Hepu waterpump.

I had my issues with the 2nd gen (water pump failure)

a Hepu which went seven years/60,000 miles before it started leaking. I think the additional mass of the metal impeller put more stress on the bearing and seal.
