1989 Isuzu Trooper ii problems
The Isuzu Trooper is a full-size SUV that was produced by the Japanese automaker Isuzu between September 1981 and September 2002. In the domestic Japanese market it was sold as the Isuzu Bighorn, the car was exported internationally mainly as a Trooper but it also received several other nameplates including Acura SLX, Chevrolet Trooper, Subaru Bighorn, SsangYong Korando Family, Honda Horizon, Opel Monterey, Vauxhall Monterey, Holden Jackaroo, and Holden Monterey.
In total, there were two generations of this vehicle: the first, produced between 1981 and 1991; and the second (UBS) produced between 1991 and 2002, with a substantial refresh in 1998.
The Trooper began as a rather basic and somewhat underpowered on- and off-road vehicle, offered only with four-cylinder motor, four-speed manual transmission, and part-time four-wheel drive. The first generation evolved to add both amenities and luxuries, including optional air-conditioning, power windows, and a more powerful V6 engine. The second generation was even more refined and available in two-wheel drive as well as four-wheel drive.

Common 1989 Isuzu Trooper ii problems
The Isuzu Trooper II, produced in 1989, is known to have several common problems that affect its performance and reliability.
- Engine Oil Light Illuminated: If the engine oil warning light is lit even after filling up the oil levels, it's possible that there's a leak in the differential, which tends to happen around the 55,000-mile point. Replacing the differential can help resolve this issue.
- Excessive Fuel Use and Rough Idling: These problems are often caused by a damaged intake manifold gasket or a faulty fuel pump. Installing a new intake manifold gasket or replacing the fuel pump can help improve fuel efficiency and idle quality.
- Ticking From Valve Train: This issue is typically caused by a varnish build-up in the hydraulic lash adjusters. Using a higher quality oil can help resolve this problem.
- Oil Leak: A faulty front crankshaft oil seal is the most likely cause of oil leaks in the Trooper. Replacing the oil seal with a revised design available from Breakeryard can help stop the leak.
- Rattling From Front of the Car: This problem is often caused by timing chain tensioners wearing out faster than usual. Replacing the tensioner can help reduce the rattling noise.
- Power Loss and Check Engine Light: These symptoms can indicate a failing catalytic converter, which cannot be repaired and requires replacement with a new one from BreakerYard.
- 4WD Indicator Staying On: This issue can be caused by faulty vacuum hoses, solenoids, or engine valves. Replacing the faulty part can help resolve the problem.
- Fuel Pump Failure: This problem can cause the vehicle to die for no reason and may require replacing the fuel pump, which can be done by following online guides for self-installation .
These common problems with the Isuzu Trooper II 1989 can affect its performance and reliability, and addressing these issues can help improve the overall driving experience.
