I’m trying to fix a coolant leak on my lawn mower, I took the water pump off and it looks fine. I’m wondering if the seal just broke. Looking for advice on how to proceed.
My John Deere x720 started overheating late last year. I noticed it was going through coolant almost immediately. After poking around I found coolant leaking down the side of my engine.
The coolant leak is isolated right under the water pump. I bought and have a new pump, but it’s a $250 part.
After disassembling the old water pump, it doesn’t look like anything is damaged. The gasket is the type that comes in a tube and I’m assuming it just broke.
Should I replace the water pump since I have it? Can I just clean the old one and put it back? Why does a water pump leak?

Seals wear out, and yes replace it.
The water pump turns with the motor, the seals wear out, and a little leakage is an indicator it’s going bad. Replace all of it
