Holden Jackaroo Q&As

Check out real-world situations relating to the Holden Jackaroo here, particularly what our experts have to say about them.

• Gears not working in 1992 Holden Jackaroo

  There are two possibilities here. Either the shifter mechanism has jammed or failed and will only allow you to select second or fourth or, the gearbox itself has failed internally, and the ensuing mechanical carnage has jammed it up. The wild-card is the clutch which could have failed. If that was the case, though, I’d imagine you wouldn’t be able to select any gears at all with the engine running.

  The first step would be to check from underneath whether the gear linkages and selectors have somehow got tangled up in each other – it can happen – but if that’s not the case, then I’m afraid it’s probably a gearbox-out job. Make sure you fit a new clutch when it all goes back together.

• Holden Jackaroo 2000: What's causing the engine to rattle and blow smoke?

  It could be a problem with the diesel pump, it might be a problem with the turbocharger, or it could even be an internal problem with the engine itself. Get it to a diesel mechanic for a proper diagnosis.

• Jackaroo gasket

  It could be a blown head gasket as your mechanic suggests, but he should be able to test it to determine if it is blown or not. You should also be able to see evidence in the form of a milky substance in the coolant if it is a blown head gasket.

• Turbo-diesel difficult to start

  I would suggest you seek out a diesel specialist to work on your car. It is valued at about $8000 at best on the used car market, and that's when it's running well, so that should give you an idea of what to spend on it.
