When the dashboard temperature gauge on your 2017 Explorer begins to climb, the culprit is often the water pump. This critical component circulates coolant through the engine and heater core, preventing overheating and ensuring optimal operating temperature. For the 2017 Ford Explorer, replacing the water pump is a standard maintenance procedure that, if addressed promptly, can save you from more extensive and costly engine repairs down the line.
Understanding the 2017 Explorer Cooling System
The 2017 Explorer utilizes a sophisticated closed-loop cooling system designed to manage the high thermal loads of its available V6 engine. The water pump is driven by the timing chain, meaning that labor is involved whenever access is required. Recognizing the signs of failure—such as steam from the hood, a sweet chemical odor, or unexplained puddles of green or orange fluid—is the first step in diagnosing the issue before it leads to engine damage.
Signs Your Water Pump Needs Replacement
Identifying a failing water pump early can prevent a roadside breakdown. Owners of the 2017 model year should watch for specific symptoms. A whining noise from the front of the engine often indicates a worn bearing within the pump assembly. Additionally, if the heater is blowing cold air while the engine runs hot, it suggests the coolant is not circulating properly, pointing directly to the pump or its associated components.
Preparation and Safety Protocols
Safety is paramount when working under the hood. Before beginning the 2017 Explorer water pump replacement, ensure the engine is completely cool to avoid burns from residual heat. Disconnecting the negative battery terminal is essential to prevent any electrical shorts. Furthermore, having the correct tools, such as a torque wrench and a serpentine belt tool, is necessary to complete the job correctly the first time.
Step-by-Step Replacement Procedure
Accessing the water pump on the 2017 Explorer requires removing several components. While the exact process can vary based on engine configuration, the general steps involve draining the coolant, removing the timing belt cover, and unbolting the old pump. It is highly recommended to replace the timing belt if it is near the end of its service life during this procedure, as accessing the pump requires removing the belt regardless.
Draining and Disposal
Draining the coolant is the logical first step. Place a drain pan beneath the radiator petcock. Once the fluid has fully drained, ensure proper disposal of the old coolant, as it is toxic to animals and the environment. Refilling with the manufacturer-specified type of coolant is crucial for maintaining the integrity of the aluminum engine components.
Hardware Inspection and Installation
With the old pump removed, inspect the mounting surface for any debris or corrosion. Cleaning this area thoroughly ensures a proper seal for the new unit. When installing the replacement pump, apply a fresh layer of sealant or use a new gasket as directed. Reassembly must follow a specific order, and all bolts should be tightened to the factory specifications using a torque wrench to prevent warping or future leaks.
Cost Analysis and Professional vs. DIY
For the 2017 Explorer, the cost of a water pump replacement varies significantly based on labor rates and whether you perform the work yourself. Purchasing the part itself can range from $150 to $350. If opting for a dealership, the total bill can climb to over $1,000 due to the labor intensity. A competent DIY enthusiast can save a substantial amount of money, though the job typically requires 4 to 6 hours of focused work.
