A Cautionary Note:
All diesel engines are interference engines - this means that if the timing belt or the timing tensioner pulley bearing fails, then the pistons will contact the valves potentially causing severe (read: very expensive) engine damage.
Proper repair procedures require that all of the timing components and the water pump are replaced at the Toyota recommended replacement interval of 100,000kms or 5 years, whichever comes first, or what is listed in your Factory Service Manual if it differs from this recommendation.
It is further recommended that other parts are inspected and replaced as necessary, including belts, radiator and heater hoses, thermostat and gasket, along with engine coolant at the proper concentration.
Pro Tips:
When replacing your timing belt we always recommend that you also replace your tensioner pulley and spring - these parts are included in the kit.
The cam seal and injection pump gear seal are also worth doing, and come in the kit.
When replacing the timing components, it is also worth replacing the water pump at the same time. The water pump lifespan is only somewhat longer than the timing components, and the timing components need to be removed to replace the water pump, making this a worthwhile combination job.
Other parts that should be replaced:
- Water Pump 16100-19235
- Valve cover gasket 11213-17010 (aftermarket)
- Valve cover gasket 11213-17010 (Genuine)
- Thermostat with gasket 90916-03089
- Radiator Hoses for HDJ80 / HDJ81 / HZJ80 Upper Hose HDJ81 Lower Hose HDJ81
You will need two 4L jugs of concentrated coolant, and a new rad cap is good idea too - 16401-71010
Components from Japan
Note: Due to availability problems the tensioner bearing may be from several different manufacturers, and different than the product photograph.
