water pump

[jaykay]

My box is 10+ years old an I have never changed the water pump. What are the dangers of this....?

According to Jake Raby (Flat 6 Innovations), the highest risk is the plastic impellers breaking and lodging in the cooling passages in the cylinder head. Not so much mileage, but age can make the plastic brittle; I would venture you are on borrowed time. My 3.2 is going to be 9 years old this spring with only 19k miles on the clock...I plan to replace the pump just as a precaution.

Great more plastic parts..........agreed the thing needs to come out. Had no clue the impeller was plastic

I've been thinking of changing mine for the same reason. 12+ years old with 127k miles. NAPA has a reman for $144 or new for $158. Has anybody used one of these from NAPA ?

Why cant we get a metal impeller replacement ?

I'd double check that "new" price. I sell a reman for $160.00 and the new pump is $358.00.

I installed the Napa remanufactured pump just after Labor Day, when mine went bye-bye during a drive through the Rockies.

So far, so good.

Since its a lifetime warranty from Napa, I have more confidence in it, than something that came from some other type of shop that has part suppliers of less than stellar quality.

Plus, they also had the lowest core charge out of all the sources I looked at.

Change all water pumps after 3 years of service, despite mileage. After 3 years the heat, coolant and time in service have proven to create issues that cost engines.

If you drive your car 300 miles in 3 years, you still must change the pump to avoid the costly failures associated with the partial water pump failure that put 12 cars from 11 different states in my parking lot right now.
