Gates 42163 Engine Water Pump

Gates 42163 Engine Water Pump Overview

The Gates 42163 engine water pump is a standard replacement for select Hyundai, Mitsubishi, and Plymouth applications. Built with a cast aluminum housing and cast iron impeller, it is engineered for dependable coolant circulation in vehicles such as the Hyundai Sonata, Hyundai Elantra, Mitsubishi Eclipse, Mitsubishi Galant, and Plymouth Laser.

Gates Water Pump (Standard) components are built for OE-quality fit and are tested for seal and bearing function as well as leakage before release. This makes the 42163 a practical choice when replacing a worn water pump on a 1990s Hyundai Sonata or Mitsubishi Eclipse cooling system.

Detailed Product Description

The Gates 42163 water pump is designed for direct replacement service on compatible Hyundai Sonata and Elantra models, along with Mitsubishi Eclipse, Mitsubishi Galant, and Plymouth Laser applications. Its standard impeller rotation and accessory belt drive style match the original cooling system layout on listed vehicles. The cast aluminum housing and cast iron impeller support durable operation in everyday engine cooling service.

This part cross-references Airtex AW9212 and Dayco DP591 for the same application. If you are servicing a 1992-1998 Hyundai Sonata, 1993-1995 Hyundai Elantra, 1990-1994 Mitsubishi Eclipse, 1990-1994 Plymouth Laser, or 1989-1992 Mitsubishi Galant, the Gates 42163 provides a fitment-specific replacement option.

What This Water Pump Helps Address

• Coolant circulation problems caused by a worn pump
• Engine overheating from reduced coolant flow
• Coolant leakage at the pump casting or seal area
• Bearing noise or rough operation from pump wear
• Cooling system service on listed Hyundai, Mitsubishi, and Plymouth models

Installation Notes and Tips

Verify engine application and accessory belt drive layout before installation. Replace the gasket and O-ring supplied with the pump, and inspect the belt, hoses, and mating surfaces for wear or contamination. Because this pump is not timing belt driven, installation follows the accessory belt cooling system arrangement used on the listed vehicles.

For fitment-focused searches, this part is commonly selected for a 1992-1998 Hyundai Sonata water pump replacement, a 1993-1995 Hyundai Elantra cooling repair, or a 1990-1994 Mitsubishi Eclipse engine water pump service.

Quality Assurance

Gates manufactures this water pump with premium alloy materials and performs functional testing of seals and bearings, along with leakage testing of the casting and assembled unit, to support consistent service quality and OE-quality fit.
