Diagnosing Problems With Your Water Pump
The water pump plays a critical role in engine cooling. Whether you drive a Dodge Durango, a Jeep Grand Wagoneer, or another model, a failing water pump can quickly lead to overheating and severe engine damage.
What Role Does the Water Pump Play?
The water pump circulates coolant through the engine and radiator. It helps maintain the ideal operating temperature, thus preventing your engine from overheating.
How to Know Your Radiator Is OK, But Water Pump Is Bad?
- Coolant leaks from the water pump area, but the radiator is intact.
- Grinding or whining noise from the pump’s bearing.
- Engine temperature rising despite full coolant levels.
- Visible rust or corrosion on the pump housing.
These are signs that it's probably the water pump that's problematic, and not the radiator:
Quick Tips in Testing Your Jeep's or Dodge's Water Pump
- Check for coolant seepage around the pump seal.
- Spin the pulley to detect roughness or play.
- Use a mechanic’s stethoscope to listen for bearing noise.
- Inspect for wobbling while the engine runs.
