Detailed Product Overview

This GMB timing belt kit is built for engine timing service on vehicles that require coordinated replacement of the belt, tensioning components, balance shaft parts, and water pump. The 3440-0303 kit is a direct-fit service solution for 1998-2004 Isuzu Rodeo, 2002-2003 Isuzu Axiom, 2001-2003 Isuzu Rodeo Sport, 1998-2002 Honda Passport, 1998-2002 Isuzu Trooper, 1999-2001 Isuzu VehiCROSS, and 1998-1999 Acura SLX. It is also a strong match for shoppers searching for an Isuzu Rodeo timing belt kit with water pump or a Honda Passport timing belt replacement kit.

Because the kit includes the timing belt, timing belt tensioner, hydraulic actuator, water pump, and water pump pulley, it supports a full timing service rather than a partial repair. The balance shaft belt, idler, and tensioner are also included where required by application. GMB 3440-0303 is an OEM-standard replacement built for vehicles that need precise timing system service, including Isuzu Rodeo, Honda Passport, and related V6 applications.

Common Problems This Kit Addresses

• Worn or cracked timing belt
• Noisy or weak timing belt tensioning components
• Coolant leaks from the water pump area
• Timing system service due at scheduled maintenance intervals
• Balance shaft belt wear or tension loss

Installation Notes and Tips

Replace the timing belt, tensioner, hydraulic actuator, and water pump together during timing service to reduce repeat labor. Verify engine code, accessory layout, and existing component match before installation, since timing components can vary by application. Follow factory timing marks and service procedures carefully, and inspect related seals, pulleys, and coolant condition while the front of the engine is accessible.
