Gates 42208 Engine Water Pump

Overview

The Gates 42208 engine water pump is built for cooling-system service where durable materials and verified sealing matter. It uses a cast aluminum housing and a stamped steel impeller, with standard rotation and accessory-belt drive for the listed application.

Compatible with 1987 Subaru Standard cooling-system service, this water pump is identified by part number 42208 and is backed by Gates’ OE-quality fit approach.

Key Features

• Cast aluminum housing for corrosion-resistant cooling-system construction
• Stamped steel impeller with standard rotation
• Accessory-belt driven design
• Includes water pump, 2 gaskets, O-ring, and 4 double-end studs
• 100% functional testing of seals and bearings
• 100% leakage testing of the casting and assembled pump

Product Details

Gates 42208 is an engine water pump for applications that use an accessory belt rather than a timing belt. The pump is built with premium alloy materials and is tested for seal, bearing, and leakage performance before release. Its two-outlet design and standard impeller rotation support proper coolant circulation in the specified Subaru application. If you are replacing a worn Subaru water pump, 42208 provides a direct service part reference for the cooling system.

This part cross-references Airtex AW9161 and GMB 160-1130 for the same application.

Common Problems This Part Can Address

• Coolant leakage from a worn pump housing or seal
• Noise from failing pump bearings
• Reduced coolant circulation from impeller wear
• Overheating caused by pump performance loss
• Cooling-system service needs on an accessory-belt-driven setup

Installation Notes

Verify the application details, including hub height and drive style, before installation. Replace the gaskets and O-ring during service and inspect the belt-driven cooling components for wear. Confirm that the pump orientation and outlet layout match the original configuration for the vehicle.

Quality Assurance

Gates manufactures this water pump with premium alloy materials and performs 100% seal and bearing function testing plus 100% leakage testing on both the casting and assembled unit. The Gates Water Pump (Standard) line is positioned as an OE-quality replacement solution.
