The water pump is a vital component of the engine cooling system of any car. It ensures that the engine runs at the right temperature by circulating coolant through the engine block, cylinder heads, and radiator. A faulty water pump can cause serious engine damage and lead to costly repairs. In this article, we will discuss the 2017 Ford Explorer water pump, its function, signs of a failing water pump, and how to replace it.
What is a Water Pump?
The water pump is a mechanical device that circulates coolant through the engine block and cylinder heads. It is driven by a belt or chain connected to the engine crankshaft. The water pump has impellers that spin and create a flow of coolant through the engine. The coolant absorbs heat from the engine and carries it to the radiator where it is cooled by air passing through the radiator fins. The cooled coolant then returns to the engine to absorb more heat.
Signs of a Failing Water Pump
The water pump is a durable component, but it can fail over time due to wear and tear. Some signs of a failing water pump include:
- Leaking coolant from the water pump
- Engine overheating
- Noisy water pump
- Low coolant level
- Steam coming from the engine
If you notice any of these signs, it is important to have your vehicle inspected by a mechanic to avoid costly engine damage.
How to Replace a Water Pump
Replacing a water pump can be a complex task, and it is recommended to have it done by a professional mechanic. However, if you have the necessary knowledge and tools, you can replace the water pump yourself. Here are the general steps to replace a water pump:
- Disconnect the negative battery cable
- Drain the coolant from the engine
- Remove the drive belt or chain that connects the water pump to the engine
- Remove the water pump pulley
- Remove the water pump bolts and the water pump itself
- Clean the gasket surfaces on the engine block and the water pump
- Install the new water pump and gasket
- Tighten the water pump bolts to the manufacturer's specifications
- Reinstall the water pump pulley and the drive belt or chain
- Refill the coolant system with the recommended coolant
- Start the engine and check for leaks
Conclusion
The water pump is an important component of the engine cooling system of the 2017 Ford Explorer. It helps regulate the temperature of the engine and prevent serious engine damage. Signs of a failing water pump include coolant leaks, engine overheating, and low coolant levels. Replacing a water pump can be a complex task, and it is recommended to have it done by a professional mechanic. However, if you have the necessary knowledge and tools, you can replace the water pump yourself. Always follow the manufacturer's instructions and use the recommended replacement parts and coolant.
