2.0L J20A (4-cylinder)
Petrol
Listen carefully for a 'whine' or 'growl' from the transmission or differential while driving at 80km/h; these older 4WD systems can experience bearing wear over time.
Engage the 4WD lever while stationary in neutral to ensure it shifts smoothly; stiff linkages are common in these older units and may require cleaning or lubrication.
Opening the radiator cap when the engine is completely cold to check for signs of oil contamination or 'milky' coolant, as the J20A engine can be sensitive to cooling system neglect.
Inspecting the underside for fluid leaks around the front and rear main seals; in cars of this age, minor weeping is often seen, but heavy oil staining suggests a deeper investigation.
Usually marks the point where cooling system components like the radiator and hoses might show signs of fatigue.
A common window to check suspension bushings and shock absorbers to maintain that classic Suzuki handling feel.
The time to ensure the timing chain tensioner has been monitored or replaced to maintain optimal engine timing.
Keep the engine happy with regular oil changes using a high-quality 10W-30 or 10W-40 oil.
Periodically check the transmission and differential gear oils to ensure smooth drivetrain operation.
Keep the cooling system topped up and look for any brittle radiator hoses that may need a refresh.
Inspect the brake pads and rotors regularly, especially if you use the Grand Vitara for light off-road excursions.
Clean the air filter regularly to help the J20A engine breathe efficiently and maintain fuel economy.
Estimated repair costs if issues arise
While the J20A is a reliable engine, if you notice a rattling sound at start-up, it is worth looking into the timing chain tensioner. Depending on the car's history, you might eventually need to budget for a chain and tensioner service to keep everything running smoothly.
If the ride feels a bit 'bouncy' or you notice knocking over bumps, it is common to consider replacing the shock absorbers and bushes. If this component needs attention in the future, the estimated cost in NZ is dependent on whether you choose standard replacements or upgraded off-road components.
As these vehicles age, the plastic tanks on the radiator can become brittle. It is wise to consider this as part of your future budget planning to prevent overheating issues down the track.
