• Includes timing belt, timing belt tensioner, hydraulic actuator, water pump, and water pump pulley
• OEM Standard item grade for OE-style replacement service
• Standard replacement timing set design
• Rubber timing belt material

Detailed Product Overview

This GMB timing belt kit is built for engine service on 1995-2004 Toyota Tacoma, 2000-2004 Toyota Tundra, 1996-2002 Toyota 4Runner, and 1995-1998 Toyota T100. Part number 3470-0271 is designed as a standard replacement solution for timing system maintenance, helping restore proper camshaft and crankshaft synchronization while also replacing the water pump at the same time.

This part cross-references Gates TCKWP271B and Dayco WP271K1C for the same application.

Common Service Issues Addressed

• Timing belt wear, cracking, or age-related deterioration
• Noise or rough operation from worn tensioning components
• Coolant leaks from a failing water pump
• Loss of timing accuracy caused by stretched or damaged belt components
• Balance shaft service needs on supported Toyota engines

Installation Notes and Tips

Verify engine configuration before ordering, especially for Tacoma, Tundra, and T100 applications with a bypass tube on the housing. Replace related timing components during the same service interval and confirm all timing marks are aligned before engine startup. Because this kit includes the water pump, it is well suited for a full timing service rather than a belt-only repair.

Quality Assurance

GMB states that this kit is manufactured to meet or exceed OEM specifications. Part number 3470-0271 is built to OEM-standard expectations for fit and function on the listed Toyota vehicles.
