GMB 3420-0153 Engine Timing Belt Kit with Water Pump

The GMB 3420-0153 is a complete engine timing belt kit with water pump — a convenient, all-in-one solution designed to restore your vehicle's timing system to like-new condition. GMB is a major OEM supplier with decades of manufacturing experience, providing parts to automakers including Hyundai, Kia, GM, and Chrysler.

This kit bundles every critical timing service component into a single box, saving time on installation and ensuring all parts are replaced simultaneously for maximum reliability and belt longevity.

Kit Includes:

• Timing Belt — sourced directly from OEM belt manufacturers including Mitsuboshi, Bando, and Continental
• Water Pump — GMB-manufactured to match OE coolant flow rate and pressure, with a premium-quality bearing for quiet operation and long service life
• Timing Belt Tensioner — built using advanced bearing technology with automatic defect detection during manufacturing
• Hydraulic Tensioner (where applicable)
• Idler Bearing/Pulley
• Camshaft and Crankshaft Seals — OEM-sourced to ensure proper grease retention

Why Replace the Full Kit?

A worn water pump or tensioner can prematurely wear a new timing belt, leading to early failure. Replacing all timing system components at the same interval maximizes belt life, reduces repeat labor, and ensures every part meets or exceeds OEM performance standards. All GMB Timing Belt Kit components are manufactured to strict OEM specifications in GMB's own facilities in Japan, Korea, Thailand, and China.
