Water pumps rarely explode; they leak, whine and wobble their way out over weeks.
Listen and look before it lets go
A failing pump announces itself: a coolant drip or crust at the weep hole under the pump, a grinding or whining that follows engine speed, a wobble in the pulley, or gradual overheating in traffic. On many engines the pump is driven by the timing belt — one more reason those two get replaced together, while the labor is already paid for.
Quick tips
- A dried coolant trail below the pump counts as a leak even if it is not dripping today
- Bearing growl that changes with RPM is the pump or a pulley — narrow it down with a stethoscope
- Never trust a pump that has been run hot repeatedly; the seal is the first casualty
