Isuzu Trooper II 1991–2002 Typical Malfunctions

🔧 Engine (6VD1 / 6VE1):

Increased oil consumption (especially 6VE1 3.5L)

Causes: wear of oil scraper rings, crankcase ventilation (PCV), coking.

Consequences: smoke, sticking of rings, risk of cylinder scoring.

Leaking valve cover gaskets and timing cover

Oil leaks on exhaust manifolds, possible burning smell.

Engine overheating

Causes: clogged radiator, faulty thermostat, coolant leaks.

Vulnerable point - intake manifold (antifreeze leak).

Unstable idling

Often associated with contamination of the throttle valve or malfunction of the IACV (idle air control valve).

 

⚡ Electrical:

Instrument cluster malfunctions

Flashing lights, unstable speedometer/tachometer readings.

Generator malfunctions

Charging problems, in some cases short circuit of diodes.

 

⚙️ Transmission:

Automatic transmission (4L30-E)

Overheating, kicks, delayed shifting.

Often caused by dirty oil, clogged filter or overheating.

Transfer case (TOD – Torque on Demand)

Failures are possible due to wear of sensors or failure of the transfer case ECU.

 

🛞 Chassis:

Front suspension — rapid wear of ball joints and stabilizer bushings

Play and extraneous knocking are possible.

Front differential and drive seal leaks

 

🧊 Other:

Rear frame corrosion (especially in northern regions)

Often leads to technical inspection failure.

ABS and "Check TOD" system failures

Causes: dirt on wheel speed sensors, worn wiring.
