Description

This NAPA NTTKH1059 Premium Timing Belt Kit is engineered specifically for Toyota 4.2L 1H-Z diesel engines used across Land Cruiser 70, 77, 79, 100 Series and Toyota Coaster models. Built to exacting OE standards, this kit includes a heavy-duty timing belt, hydraulic tensioner and seal kit to ensure stable belt tension, smooth camshaft operation and long service life in demanding conditions.

The 1H-Z engine is widely used throughout New Zealand in commercial vehicles, rural transport, off-road fleets and tourism operators. Regular timing system replacement is essential to prevent belt slippage or breakage, especially under heavy load or dusty environments typical in NZ. This complete kit provides all the core components needed for a reliable service-interval repair.

Designed for vehicles requiring a hydraulic-actuated tensioner, this kit ensures correct belt tensioning, reduced engine noise and increased operational reliability.
