7 Common Nissan Navara D40 Problems and How to Fix Them

A lot of people who drive a Navara D40 start noticing issues once the vehicle gets older or crosses high mileage. These utes are often used for towing, work sites, and long drives. That puts more stress on the engine and drivetrain.

So, problems begin to show up. It may start with engine noise, overheating, power loss, or gear issues.

The direct answer is simple. Most Navara D40 problems come from a few parts that wear out over time. Once the faulty part is identified, the fix is usually straightforward. Sometimes it is a repair.

Other times, replacing the part makes more sense.

Below are the problems we see most often and how they are normally fixed in the workshop.

Common Navara D40 Problems and How They to Fix Them 

1. Timing Chain Rattle in Navara D40 Engines

The timing chain is a common issue in older Navara D40 diesel engines.

Owners usually notice a rattling sound from the engine, especially during cold starts.

Common signs of timing chain wear

• Rattling noise from the front of the engine
• Engine running rough at times
• Engine warning light appearing
• Loss of power while driving

This happens because the timing chain stretches after long use.

What usually fixes the problem

• Replace the timing chain kit
• Change chain guides and tensioners
• Reset the engine timing properly

If the chain has been loose for too long, internal engine parts may wear. In that case a full repair can become expensive.

Some owners decide to replace the motor instead. At All Good Parts, we often help customers find used engines from dismantled vehicles when rebuilding the original engine is no longer practical.

2. Engine Overheating Issues

Drivers normally notice the temperature gauge climbing higher than usual or coolant leaking.

Overheating is another problem seen in many older Navara D40 vehicles.

Common causes of overheating

• Blocked or ageing radiator
• Faulty thermostat
• Water pump wear
• Low coolant level
• Cooling fan problems

Heavy towing and long drives often make this issue appear earlier.

How the problem is usually fixed

• Inspect the coolant level and the cooling system
• Check radiator condition
• Replace the thermostat if it fails to open
• Inspect the water pump for leaks or noise

But repeated overheating can damage the engine.

• This can lead to:
• Blown head gasket
• Warped cylinder head
• Internal engine damage

When that happens, many drivers look for a replacement motor. That is why All Good 

Parts supply tested replacement engines for the Navara D40 from dismantled vehicles.

3. Turbocharger Power Loss

Turbo issues are also common in diesel Navara D40 models with high kilometres.

The problem usually shows up as a sudden drop in engine power.

Signs the turbo may be failing

• Vehicle struggles to accelerate
• Whistling sound from the engine area
• Black or blue smoke from the exhaust
• Oil around the turbo pipes or hoses

Turbochargers rely on clean engine oil to stay lubricated. When oil changes are delayed, internal turbo bearings wear faster.

Normal inspection process

• Check turbo shaft movement
• Inspect oil feed lines
• Look for oil leaks in intake pipes

Typical solution

• Replace the worn turbocharger

If the turbo breaks internally, metal fragments can sometimes enter the engine. When that happens, the engine itself may suffer damage.

In these cases, some owners choose a replacement motor instead of repairing multiple parts. 

Through All Good Parts’ used engine stock, customers can often find a suitable Navara engine removed from a working vehicle.

4. Clutch and Gearbox Wear

Manual Navara D40 models often develop clutch problems over time. This is common in vehicles used for towing trailers or carrying heavy loads.

Symptoms drivers usually report

• Gears becoming harder to change
• Clutch slipping during acceleration
• Burning smell when driving uphill
• Clutch pedal feeling softer than normal

Clutch parts simply wear out after long use.

Typical clutch repair includes

• Replacing the clutch plate
• Installing a new pressure plate
• Inspecting or resurfacing the flywheel

Sometimes gearbox wear also appears.

Possible gearbox signs

• Grinding noise during gear changes
• Difficulty selecting gears
• Gearbox vibration or humming noise

When internal gearbox parts wear badly, replacing the gearbox from a dismantled vehicle is sometimes the more practical option.

5. Suspension and Steering Wear

Suspension parts on the Navara D40 take a lot of stress, especially on work vehicles.

Over time, the components begin to wear.

Common signs of suspension wear

• Knocking noise when driving over bumps
• Loose or vague steering feel
• Vehicle pulling slightly to one side
• Uneven tyre wear

Parts that usually wear first

• Control arm bushes
• Ball joints
• Shock absorbers
• Tie rod ends

These parts handle constant movement and weight.

Typical repair process

• Inspect suspension joints and bushes
• Replace worn ball joints or bushes
• Install new shock absorbers if needed
• Perform wheel alignment after repairs

Once these parts are replaced, the vehicle normally drives much more stable.

6. Oil Leaks in Older Navara Engines

Oil leaks are common once Navara D40 engines reach higher mileage. Most leaks come from ageing seals and gaskets.

Signs of an oil leak

• Oil spots under the parked vehicle
• Burning oil smell after driving
• Engine oil level dropping between services

Common leak locations

• Rocker cover gasket
• Rear main seal
• Turbo oil lines
• Oil filter housing seals

How mechanics usually find the leak

• Clean the engine area first
• Run the engine and check where oil appears
• Replace the faulty gasket or seal

Small leaks are easy to fix.

But if oil levels stay low for long periods, the engine can suffer internal wear. Bearings and pistons depend on proper lubrication.

When engines are badly worn, some owners choose a replacement motor instead of rebuilding. That is why All Good Parts keeps inspecting used Navara engines available from dismantled vehicles.

7. Electrical Problems in Older Navara D40 Vehicles

As the vehicle ages, some electrical parts may start failing. These issues usually appear slowly.

Common electrical faults

• Dashboard warning lights staying on
• Power window motors failing
• Starter motor problems
• Battery draining overnight

Typical checks done in the workshop

• Scan the vehicle for fault codes
• Test battery and alternator output
• Inspect wiring connections
• Replace faulty sensors or motors

Most electrical faults are fixed once the faulty component is identified.

Conclusion

The Navara D40 can last a long time when problems are handled early.

A few simple checks make a big difference.

• Listen for new engine noises
• Check coolant and oil levels regularly
• Fix overheating immediately
• Keep up with regular oil changes

When a major engine failure happens, repairing every damaged part is not always practical.

That is why many drivers choose a used replacement engine instead. At All Good Parts, we supply inspected Navara D40 engines removed from running vehicles so owners can get their ute back on the road without paying for a brand new motor.

Fix small problems early. It keeps the vehicle working longer and avoids larger repairs later.
