Australia's utility market is a big deal - Toyota's HiLux was the country's top-selling vehicle in 2016 - and competition is fierce for the lucrative worksite dollar. Enter Nissan's Navara, historically one of Nissan's best-selling models and a near constant sight at worksites across the country. Available in a huge array of configurations, including a cab chassis (tray back) or pick-up body style with three different cabin sizes, and with rear- or all-wheel drive, the Navara can be simple or as tech-laden as its customers want. Although it varies by variant it is usually a three-engine option model, with a choice of two diesel or one petrol engine.
This vehicle is also known as Nissan Frontier (North America), Nissan NP300 (Mexico, Europe).
There is a tapping noise from the motor of my 2007 Nissan Navara
This sounds like a classic case of a hydraulic lifter (also called a lash adjuster) that is dying a slow death. These components rely on engine oil pressure to maintain the correct clearance between the engine valves and the rockers that actuate them, and any wear will show up as a ticking noise when the engine is first started and is still building oil pressure. They can often 'tick' for a few seconds or more before going quiet.
The recurrence of the noise has probably got something to do with a fall in oil pressure at idle when the engine warms up, allowing the lifter to start ticking again. But the engines in this series of Navara were also known for ticking or rattling noises as the result of worn camshaft-chain tensioners, broken or damaged cam bearing bolts and wear in the auxiliary pulleys and belt tensioners. If the noise does turn out to be a dud lifter, do the smart thing and replace them all, as wear in one means certain wear beginning in the others.
What is the GCM of a 2005 Nissan Navara?
The towing limit on this model Navara varies enormously according to what engine and transmission is fitted. As a result, the Gross Combination Mass (GCM) also varies a lot between models. As such, the 2.4-litre petrol Navara has a GCM of 4230kg, the V6 petrol a GCM of 4850 and the turbo-diesel is much higher at 5920kg.
Don't forget, the GCM includes the vehicle, whatever it's towing and everything else on board, including fuel, accessories and even passengers.
Does my Nissan Navara have a diesel particulate filter?
You haven't given me much to go on with here, Noel. Without the year and specification of your Navara, I can't even guess if it was fitted with a DPF or not. That's because Nissan has had a bit of an on-again-off-again relationship with DPF technology. To the extent that in some versions of the Navara, the automatic variant had a DPF and the manual did not.
But you can check for yourself by taking a look under the car. A DPF looks a bit like a muffler, but with a couple of metal pipes coming out of it and usually an electrical connection or two. Some of this stuff may be hidden behind heat shields, however. In most cases the Navara's DPF will be located in the middle section of the exhaust system, roughly beneath the front passenger's seat.
