GMB 3446-0318 Timing Belt Kit with Water Pump and Components

The GMB 3446-0318 is a complete engine timing belt kit with water pump, engineered to restore the entire timing and cooling system in a single service event. As a major OEM supplier and aftermarket manufacturer, GMB delivers parts that meet or exceed original equipment standards — so you get factory-level reliability without the dealership price.

What's Included:

• Timing Belt — sourced directly from OEM belt manufacturers for precise fit and durability
• Water Pump — engineered to match OE coolant flow rate and pressure specifications
• Timing Belt Tensioner(s) — manufactured with advanced bearing technology and automatic defect detection
• Idler Pulley(s) — precision components to maintain proper belt alignment and tension
• Camshaft and Crankshaft Seals — OEM-quality seals to ensure proper grease retention and prevent leaks

Why Replace Everything at Once?

GMB recommends replacing the timing belt, tensioners, idler bearings, water pump, and camshaft/crankshaft seals simultaneously. A worn tensioner or failing water pump can accelerate wear on a new timing belt and lead to premature failure. Replacing the full system at once maximizes timing belt life, reduces total labor time, and lowers long-term maintenance costs.

GMB water pumps are manufactured in facilities across Japan, Korea, Thailand, and China under strict OEM specifications. GMB has served OE automakers including Hyundai, Kia, GM, and Chrysler for decades, bringing that same manufacturing rigor to the aftermarket. The GMB 3446-0318 timing belt and water pump kit is the smart, complete solution for timing system service.
