Suggestion

There is some disagreement about the use of a water pump with a metal impeller as an improvement, and Pelican staff say it is fine to use either.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I have a 2003 996 Targa with about 36,500 miles on the car. When is it recommended to change the water pump on my car? Thanks

POST 2Original post

At 60k miles is a good time.

POST 3Original post

If you have the original water pump in your car, it very likely has a composite impeller and these impellers have a reputation for disintegrating. Since the composite ages with both use and time, and its almost 20 years, I would replace the water pump and thermostat ASAP. There is some disagreement about the use of a water pump with a metal impeller as an improvement, and Pelican staff say it is fine to use either. I replaced mine at 54K miles/20 years with the composite only to find the previous owner had already replaced it with a metal impeller. So now the car is on its third pump. At least I sleep well at night.

Check the link below. I’d take an expert view over a parts retailer. They can wear away at the engine side and wreck the engine. https://forums.pelicanparts.com/boxster-cayman-forum/992269-any-thoughts-metal-impeller-water-pump.html
