Component Location
This video focuses specifically on showing you the exact location of the mechanical water pump on the longitudinal 3.6L Pentastar V6 engine. Because the Chrysler 300 uses a rear-wheel-drive layout, the water pump is highly accessible right at the very front of the engine bay, facing the radiator. Driven directly by the serpentine belt, it is bolted to the front of the timing chain cover, sitting directly below the thermostat housing and slightly offset toward the passenger side (right side) of the vehicle. This visual guide is designed to show you precisely where to look under the hood and how to identify its mounting bolts without any guesswork.
DIY Repair Benefits
Locating the water pump assembly is the crucial first step if you are planning a DIY vehicle inspection, cooling system pressure test, or full replacement process. Knowing its exact position allows you to check the weep hole on the pump body for signs of early bearing failure, inspect the surrounding gasket line for dried pink or orange coolant crust (which often pools on the timing cover lip beneath the pulley), and handle your automotive project efficiently, saving you both time and a costly trip to the repair shop.
Bad Water Pump Symptoms
A malfunctioning or worn-out water pump directly compromises the circulation of coolant through your engine block and heater cores. Common symptoms of a failing water pump on this 3.6L engine include a distinct weeping or puddle of coolant pooling under the front-center of the engine bay, a loud grinding, growling, or squealing noise from the accessory belt area due to worn internal bearings, a loose or wobbling water pump pulley, rapid engine overheating under normal driving conditions, or a low coolant warning accompanied by a sweet, burning smell coming from the front grille.
Safety First
Working around the vehicle’s accessory drive belt and pressurized cooling channels requires strict safety precautions to avoid severe injury or thermal burns. Always make sure the engine is completely cool, the vehicle is securely parked on level ground, and the cooling system is completely depressurized before unbolting any components or hoses. Crucially, do not attempt to loosen the water pump bolts or remove the radiator cap while the engine is hot, as scalding coolant can spray out under high pressure. Because the battery is located in the trunk on the Chrysler 300, make sure to disconnect the negative battery terminal there before starting to ensure the electrical circuit is completely dead. Wear appropriate safety glasses and protective gloves, use a clean drain pan beneath the radiator petcock to capture the coolant cleanly, and remain highly attentive to your surroundings to prevent any accidental injuries.
