How ofthen should you change the water pump on your vehicle?
when it stops working
I change mine every month just so it doesn't develop a leak.
only if you notice a leak.
my answer to this is ...... if it ain't broke don't fix it...... but here are some signs to let you know when the water pump if failing the most common is engine over heating,you start to see anti freeze on the ground... other than that leave it alone and also if you hear some sqealing of the belt take a look at it and see if it is glazed over or wet
Largely depend on the make and model of your vehicle. For instance, when changing timing belts for Toyota 4 Runners and Tacomas, more than 50% of water pumps already developed some leak; but for water pumps in Camrys many still in good conditions, no leaks when changing the timing belt second time.
The water pump itself isn't something that goes bad usually. Either you develop a bad bearing or a leaky seal. If no coolant comes out of the weep hole on the pump, then the seal is good. If you can grab the pulley with both hands and try to move it and feel no play or slop, then the bearings are good. If there is leakage or sloppy bearings then it's time to change the pump.
you should,nt need to change it until it goes bad.
Only if you have problems with it. OR if you are rebuilding an old engine. Don't just pull off a water pump that works, true waste of money.
