5314945 | Genuine Mopar® Water Pump For 2013-2018 Ram

The purpose of using a water pump in a vehicle is to keep the engine at a safe operating temperature by circulating coolant through the engine and radiator. Without it, the engine would overheat very quickly, which can cause serious damage like warping the cylinder head, blowing the head gasket, or even seizing the engine.

In short, the water pump:

1. Moves coolant through the engine to absorb heat.

2. Pushes hot coolant to the radiator to release heat into the air.

3. Maintains consistent engine temperature, improving efficiency and preventing damage.

• Engine Overheating – The most obvious sign. If the water pump isn’t circulating coolant properly, the engine temperature rises quickly.

• Coolant Leaks – Look for puddles or drips of coolant (usually green, orange, or pink) under the car, often near the front of the engine where the pump is located.

• Whining or Grinding Noise – A worn-out water pump bearing can make a high-pitched whining or grinding sound, especially when the engine is running.

• Steam from the Radiator – Steam coming from the hood indicates the engine is overheating due to poor coolant circulation.

• Corroded or Rusty Pump – Visible corrosion, rust, or buildup on the water pump itself can indicate slow leakage or impending failure.

• Coolant Temperature Warning Light – The dashboard warning may come on if the engine is getting too hot.

• Loose or Wobbly Water Pump Pulley – If you can move the pulley by hand or it has play, the pump is failing.
