Detailed Description

Built for vehicles that rely on a serpentine belt driven accessory layout, the Dayco DP542 water pump is used to move coolant through the engine and radiator circuit. This part number is listed for a wide range of Chrysler, Dodge, and Plymouth minivan and passenger car applications, including 2000 Chrysler Grand Voyager, 1990-2000 Dodge Caravan, and 1991-2000 Plymouth Voyager. If you are replacing a worn or leaking pump on a compatible vehicle, DP542 provides the correct fitment reference for cooling system repair.

What It Helps Fix

• Coolant leakage from a worn pump housing or seal
• Overheating caused by reduced coolant circulation
• Noise from a failing water pump bearing
• Temperature fluctuations during engine operation
• Cooling system service on serpentine belt driven vehicles

Installation Notes and Tips

Verify engine configuration and belt routing before installation. Inspect the serpentine belt, tensioner, hoses, and coolant condition during water pump replacement, and confirm the cooling system is properly filled and bled after service. Match the vehicle application carefully to the listed fitment for the Dayco DP542.

Quality Assurance

Dayco is a recognized name in engine drive and cooling system components, and the DP542 is cataloged for specific OE-style vehicle applications. Confirm fitment against the vehicle year, make, model, and serpentine belt driven system before ordering.
