OE Mopar Water Pumps

What to Do if Your Water Pump Has Failed

When your water pump fails, the engine can quickly overheat, potentially leading to severe internal damage. If your Jeep Wrangler has started showing signs of coolant leaks, high temperature readings, or unusual noises from the front of the engine, a failing water pump could be the cause.

Troubleshooting Water Pump Issues in Your Jeep

1. Check for Coolant Leaks Under the Vehicle

Look beneath the front of your Wrangler for puddles or stains, especially near the timing cover or water pump housing.

2. Inspect for Corrosion or Rust Around the Pump

Rust buildup or discoloration around the water pump may point to a slow leak or deteriorating pump seals.

3. Listen for Grinding or Whining Noises

Worn-out bearings in the water pump can cause high-pitched noises as the pulley turns.

4. Watch the Temperature Gauge

If your engine is running hotter than normal or overheating, your water pump may not be circulating coolant effectively.

5. Look for Steam From the Hood

Visible steam or a sweet smell from the engine bay usually means coolant is escaping and the system is overheating.

6. Confirm Coolant Flow in the Radiator

With the engine running and cap off (when safe), you should see coolant moving through the radiator—if not, the pump may have failed.

When replacing a faulty water pump, it’s a good idea to check your radiator as well, since both parts work together to regulate temperature. Reach out to Canada Mopar Parts for expert guidance on the best OEM parts for your Jeep.
