Water pump replacement, ideal interval?

I like to look at this water pump like if it's a timing belt on a car with an interference engine. It will work fine until it breaks. Once it's broken, you may have to replace the engine at the same time. So the smarter thing would be just to replace it on a 2010, 14 year old car. Don't wait until it stops functioning.

This water pump replacement is normally a 1 time replacement for the life of the car. Unless you plan to drive the car past 300k miles, you'll have to do this replacement 1 time and it's a done deal.

 

Yeah and it's about a 45-minute job on a bad day too unless you've got a lot of cleaning to do and housekeeping and what have you under the hood that has been neglected for a long time It's very quick and if that kind of mileage with the head gasket problems these engine have any inkling of any kind of overheating is not a good thing and the ZFXE engine a water pump is cheap some kind of insurance I would guess of course you could always just take yours off take the back plate off pull the impeller out and have a look if everything looks nice and clean you could put it back together and stick it right back on there I haven't seen any nice clean ones come apart yet even in nice clean cars with 150 plus the impeller outer plastic is starting to crack and it's just a matter of time until it curls and starts impeding the speed of the impeller when it's called upon.

 

When it fails, if ever. Why would you focus on that one thing?

 

Every 100k miles seems optimum to me, based on reports here about them failing around 150k. Could coincide with engine coolant change.
