Pre purchase vehicle inspection Perth services from CMM Automotive recently uncovered serious mechanical concerns during a 2009 Nissan Murano inspection in Wangara. Our mobile mechanic attended the vehicle’s location to assess its condition before a potential purchase.
The inspection revealed a positive CO₂ cooling system test, raising strong concerns about a leaking cylinder head gasket. Our technician also identified engine oil leaks, low engine oil, damaged wheels and worn suspension bushes.
These findings highlight the importance of arranging an independent vehicle inspection before purchasing a used car.
Mobile Car Inspection Perth in Wangara
Our car inspection Perth service helps buyers understand a vehicle’s mechanical and general condition before committing to a purchase.
CMM Automotive provides mobile inspections throughout Perth, including Wangara and surrounding suburbs.
During this inspection, our technician examined the Nissan Murano’s engine, cooling system, steering, suspension, tyres, interior and bodywork.
We also conducted a road test to assess the vehicle’s handling and identify possible steering problems.
A professional inspection can uncover expensive mechanical faults that buyers might overlook during a short test drive.
Positive CO₂ Test Indicates Possible Head Gasket Failure
The most significant finding involved the Nissan Murano’s engine cooling system.
Our technician conducted a CO₂ test to check for combustion gases entering the cooling system.
The test returned a positive result.
This strongly suggested that combustion gases were entering the cooling system, raising concerns about a leaking cylinder head gasket.
A damaged head gasket can allow combustion pressure to enter the cooling system and may contribute to overheating.
Other possible causes include cylinder head damage or internal engine problems.
Further mechanical testing would help confirm the exact source of the combustion gas leak.
Head gasket repairs can involve considerable labour and expense, making this an important finding for the potential buyer.
Low Engine Oil and Front Engine Oil Leaks
Our engine inspection identified additional mechanical concerns.
The Nissan Murano’s engine oil level was low.
Insufficient engine oil can reduce lubrication and increase wear on internal engine components.
Our technician also identified oil leaks around the front of the engine.
These leaks require further investigation to determine their source and severity.
Possible causes include deteriorated seals, gaskets or other engine components.
The combination of low engine oil and a positive CO₂ test raised concerns about the engine’s overall condition.
Our vehicle inspection Perth service helps buyers identify these problems before purchasing a vehicle.
Battery Condition and Power Steering Leak
The Nissan Murano’s battery tested in poor condition.
A weak battery can cause starting difficulties and may require replacement.
Our technician also identified a fluid leak from a power steering hose.
Power steering fluid leaks can reduce system performance and may eventually damage the steering pump.
Further investigation would help determine whether the hose requires replacement or whether other components need attention.
Identifying these faults before purchasing allows buyers to investigate repair costs.
Split Front Control Arm Bushes
Our steering and suspension inspection identified deterioration in the front control arm bushes.
The rubber bushes displayed visible splitting.
Damaged control arm bushes can allow unwanted suspension movement and affect steering precision.
They may also contribute to uneven tyre wear and reduced driving comfort.
Further assessment would determine the extent of the wear and which components require replacement.
These findings were particularly important because the road test revealed a steering concern.
A professional pre buy car inspection can identify suspension problems before they develop into more expensive repairs.
Front and Rear Wheel and Tyre Damage
Our technician identified damage affecting the Nissan Murano’s wheels and tyres.
The front rims and tyres showed visible damage.
The rear rims and tyres also displayed damage.
Damaged tyres can affect vehicle safety, particularly when driving at highway speeds.
Wheel damage may also contribute to vibration, air loss or handling problems.
Further assessment would determine whether the affected wheels and tyres require repair or replacement.
Tyre condition is an important consideration during any used vehicle inspection.
Our pre buy inspection service helps buyers understand the condition of these components before making a financial commitment.
Windscreen Cracks and Exterior Concerns
The Nissan Murano’s windscreen contained visible cracks.
Windscreen damage can affect driver visibility and may require professional repair or replacement.
The severity depends on the size and location of the damage.
Our technician also identified problems with the vehicle’s front windscreen wipers.
The wiper blades left streaks across the glass during operation.
The windscreen washer squirters also failed to operate.
These faults can reduce visibility during wet weather and require attention.
A thorough pre buy vehicle inspection helps identify both major mechanical faults and smaller safety concerns.
Interior Condition and Door Remote Problems
The Nissan Murano’s interior showed several signs of wear.
Our technician identified staining on the carpets and interior trims.
These cosmetic concerns affected the vehicle’s overall presentation.
The keyless entry system also displayed a problem.
Only one door remote operated correctly during testing.
The other remote requires further investigation to determine whether the fault involves its battery, programming or internal components.
Although these concerns are less serious than the engine problems, they may still involve additional repair expenses.
Road Test Reveals Vehicle Drifting Left
During the road test, our technician noticed that the Nissan Murano drifted towards the left.
Several mechanical problems can contribute to this condition.
Possible causes include incorrect wheel alignment, uneven tyre condition or worn suspension components.
The previously identified split control arm bushes could also contribute to the handling concern.
Damage to the wheels and tyres may also affect steering behaviour.
Further testing would help determine the exact cause.
A steering and suspension assessment would be advisable before returning the vehicle to normal road use.
Why a Nissan Murano Pre Purchase Inspection Matters
Used vehicles can develop expensive mechanical problems as they age.
A professional car inspection service helps buyers understand these risks before making a purchasing decision.
This Nissan Murano displayed several significant concerns involving the engine, cooling system, steering and suspension.
The positive CO₂ test was particularly important because it suggested a possible internal engine sealing problem.
Additional findings included low engine oil, damaged wheels, worn bushes and windscreen defects.
These problems could result in substantial repair expenses.
An independent inspection allows buyers to obtain repair estimates, negotiate the purchase price or reconsider the vehicle.
