Water pump OEM Toyota or Pierburg
Reviews
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.
Pros: engine would work well
Cons: overheating probs
My original lasted 18 years / 249k miles. The replacement one has been in place for almost 2 years / 22k miles.
Pros: long lasting, reliable
Vehicle:
Toyota Prius
Mileage: 434523 km
Get a pierburg if you can for the water pump. They’re more OEM than Mehle is for water pumps even though both are OE manufacturers.
Pros: more OEM
My 99 V6 just rolled 316k, am looking into my 2nd timing belt/water pump DIY
Pros: long-lasting engine
Cons: requires maintenance
Vehicle:
Toyota Camry
Mileage: 316000 km
I replaced mine with a pierburg one. after install it was fine till I hit a decent bump, which led to overheating limp mode (i stopped the car as soon as this happened).
Pros: fine after install
Cons: overheating limp mode
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
Pros: peace of mind
Cons: failure at 165k
Vehicle:
Toyota Prius
Mileage: 265549 km
I kind'a have some project and I need to use Pierburg CWA50, all I got in my country is this pump from benz (**A0005001986**), is it same model as Pierburg CWA50? Because the head pump is same but the connector is different (facing upwards). I tried to find specs from this model, the result is empty, can't find any clue about flow rate. I do have original code from Pierburg, which is **7.04933.56.0**, but can't find flow rate either.
Part number: A0005001986
when my original pump went bad, i went to Peirburg so that the plastic housing wouldnt crack. Pump lasted about 20,000 miles, bought another one from fcp euro for the lifetime warranty but this one lasted 20 mins before i got those same codes and overheated.
Cons: short lifespan, immediate failure
Mileage: 32187 km
I had my issues with the 2nd gen (water pump failure)
Cons: water pump failure
Vehicle:
Toyota
I've had 2 of these die in less than 1 year. Junk!
Cons: died in less than year
