Is there a definite life beyond which a typical Toyota Corolla water pump should last? This isn't one of those problematic 2008 through 2010s. This Corolla has always been dead nuts reliable since November 2006.
However, at 287,000 miles, it used up its first starter. I replaced its alternator, idler pulley and serpentine belt at the same time. Now I'm wondering about the water pump. Only worried because it just passed 300,000 miles. By the way, the odometer only goes to 299,999 and won't go any farther. Keeping track on the trip meter from here on in.
Should the water pump be replaced on general principles? It doesn't leak. It doesn't have any problems at all. But, it has 300,497 miles on it?
The water pump will tell you when it's starting to leak. It's an impeller, with a weep hole. When everything is fine, the weep hole will be dry. When the weep hole isn't dry, you will want to replace your water pump sooner, rather than later. If it's dry, just leave it alone.
There's really no set in stone mileage. It's just based on the engine's RPMs. If you drive like a bat out of hell, you will need to replace it sooner. If you drive conservatively, it will last a long time.
