Holden Captiva 2008 Q&As

Check out real-world situations relating to the Holden Captiva 2008 here, particularly what our experts have to say about them.

• My 2008 Holden Captiva is dumping water

  There are lots of places for a car to lose its coolant. The cooling system is a network of pipes, water jackets and other plumbing that is required to keep the engine cool, provide heat for the cabin and even cool the transmission.

  Obvious places for a leak to occur are any of the joints in this plumbing, the water pump itself or any of the various components that store the coolant (heater core, radiator, overflow tank). A failed welch plug will definitely cause a car to lose coolant, but it usually starts out as a small leak before developing into a bigger one as the plug deteriorates further over time.

  If the water is really running out as fast as your pour it in, the best idea is to get somebody to add water to the radiator while you look in the engine bay and under the car with a torch. A leak as big as the one you describe should be very visible.

• How do I get my 2008 Holden Captiva to burn off the Diesel Particulate Filter?

  Regardless of whether you use an additive, a car’s Diesel Particulate Filter (DPF) will still need to be cleaned (or regenerated) periodically as soot builds up in it. Short trips where the engine doesn’t get a chance to warm up properly, as well as extended periods of idling in traffic and stop-start running will all hasten this requirement.

  In the case of the Captiva diesel, the best way to manually force a regeneration is to put aside an hour and go for a decent drive. The advice from Holden in the day was to travel at more than 50km/h and at more than 2000rpm (which may mean locking the car out of overdrive) for a minimum of 25 minutes. During this process, you should not allow the speed or revs to fall below those two figures which suggests finding a decent strip of freeway to carry out this process. You should also not turn off the engine at any point in this procedure. The broad idea is to get the engine and exhaust hot enough for the filter to regenerate and clean itself.

  If, after 100km of this type of treatment, the DPF light on the dashboard hasn’t disappeared, the solution is a trip to a workshop to have the filter investigated and, potentially, hand-cleaned. Experience suggests a couple of attempts may be needed to get this to happen as it should, and in fact, the car’s computer will give you several chances to produce the desired effect before the workshop beckons.

• Holden Captiva: Limp mode

  The starting problem could be the result of an alternator that's not charging the battery. Have an auto electrician check it.

  Trying to find the cause of the engine warning lights coming on is a tough one.

  If they are on all the time then take it to a dealer or a mechanic with diagnostic gear to check the system. It must be either a wiring problem or a sensor malfunction.

• Holden Captiva: Timing case leak

  $1000 does sound like a lot of money to fix an oil leak; I reckon a local mechanic could do it for less. The cost aside I would accept the deal, the car is out of warranty and an oil leak is not something I would spend time and energy fighting over.
