Toyota Land Cruiser: 1HD-FTE timing belt replacement due (4.2 1HD-FTE turbo diesel)

The 1HD-FTE 4.2 litre turbo diesel in the 100 Series LandCruiser drives its single camshaft through a timing belt and gears, while the injection pump is driven from the timing gear train. The belt, tensioner and idler need replacing at the interval in the Toyota service schedule, and many of these engines now have no record of when it was last done. A belt that breaks stops the engine and can cause expensive damage. Treat an undocumented belt change as due.

• Engine cranks but will not start — indicates belt has already jumped or broken
• Ticking or rattling from the front of the engine, suggesting a failing tensioner pulley bearing allowing belt slack
• No service records showing belt replacement within the manufacturer-specified interval

1. 1

   Obtain full service history and verify timing belt replacement date and odometer reading.

2. 2

   Remove upper timing belt cover inspection plug or cover to inspect belt for cracking, fraying, glazing, or oil contamination.

3. 3

   Inspect tensioner pulley for play or bearing roughness.

4. 4

   Check for oil seepage around front crankshaft seal and camshaft seal that could contaminate the belt.

Parts involved: Timing belt, Turbocharger.

$900 to $14,000 at New Zealand independent workshop rates. That is for this job on its own, not for the car.

An estimate, in NZD, for the repair as normally carried out. What a specific car costs depends on which part has failed and what it damaged on the way — treat this as the floor for a negotiation, not a quote.

• “Can you show a receipt confirming when the timing belt, tensioner, and idler pulleys were last replaced?”
• “Has the front crankshaft or camshaft seal ever been replaced or inspected for leaks?”
• “What is the current odometer reading versus the last belt change mileage?”

The failure described above is documented in published sources — owner forums, technical service bulletins, recall notices and workshop write-ups — held in our fault database. The inspection instructions and the cost estimate are KickTyres’ own interpretation of them, and it is a starting point for an inspection rather than a manufacturer statement.
