Gates Water Pump Standard Line

Gates Water Pump (Standard) parts are built as OE-quality replacement components for routine cooling system repair. The 42000 follows that product line approach with premium alloy construction and testing focused on seal, bearing, and leakage performance before release.

This part cross-references Airtex AW3404 and Dayco DP1069 for the same application.

Detailed Description

Use the Gates 42000 when replacing a worn or leaking engine water pump on Jeep Cherokee, Jeep Comanche, Jeep Wrangler, Jeep J10, Jeep Wagoneer, Jeep Grand Wagoneer, Jeep CJ7, Jeep CJ5, and Jeep Scrambler applications listed in the fitment data. The reverse-rotation design and accessory-belt drive make it important to match the original cooling system configuration before installation. Gates 42000 is a direct-fit cooling component for vehicles that require this pump style.

What It Helps Fix

• Coolant leaks from a failing pump housing or seal
• Overheating caused by reduced coolant circulation

• Inspect the belt, hoses, and thermostat during water pump replacement.
• Clean the mounting surface thoroughly before installing the new pump.
• Use the correct coolant and follow the vehicle service procedure for refill and bleeding.
