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.
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 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
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.
Electric water pump is leaking, replace with an oem toyota part dont cheap out and go aftermarket on this part.
I had my issues with the 2nd gen (water pump failure)
My water pump was leaking this Fall at 235k. New mechanic showed me the leaky pump and it was oem toyota.
I’m driving a 98 Toyota Camry and just changed the water pump at 300k(which includes changing the timing belt).
Toyota / Lexus hybrids are bulletproof if taken care of. My 2007 Toyota Prius was bulletproof. The only thing that went bad was water pump at 192000 miles.
