💡 Why does an electric auxiliary coolant pump fail on high mileage vehicles?
The mechanical internals degrade from constant vibration and chemical exposure in hot engine bays. Here is how you can track down the exact cause before swapping parts.
- Corroded electrical pins breaking the ground connection inside the relay box
- Worn shaft seals letting pressurized fluid escape onto the drive belt
- Cracked sensor housings triggering false temperature warnings on dash clusters
- Debris clogs restricting the intake screen and killing flow rates completely
