2.5L I4 (Ecotec) - Base/Cloth Trim
Petrol
During low-speed maneuvers, listen for any hesitation in the 9-speed automatic transmission, as early units can occasionally feel a bit 'busy' or indecisive when seeking the right gear.
Spend a few minutes sitting in the cloth-trimmed seats and check the adjustment levers, as some owners have noted that the plastic housing around the base can become loose or rattle over time.
While parked, toggle the infotainment screen through several menus to ensure there is no lag or ghost-touching, as the software interface in these models occasionally benefits from a firmware update if it feels sluggish.
Before heading out, inspect the cooling system reservoir for any signs of staining, as the 2.5L Ecotec engines run at specific temperatures and maintaining optimal coolant levels is standard practice for long-term engine health.
Consider a transmission fluid flush to ensure the 9-speed unit remains smooth for the long haul.
Time to inspect the accessory drive belts and check for any minor seepage from the timing cover gasket.
Plan for a suspension health check, focusing on sway bar links and bushings, which often wear out after years of traversing local roads.
Stick to the recommended full-synthetic oil changes every 10,000km to keep the 2.5L engine running quietly.
Periodically check your cabin air filter; it is an easy DIY task that helps keep the ventilation system fresh during those humid NZ summers.
Ensure the tire pressures are set to the manufacturer's door-placard recommendation, as this helps with both ride comfort and fuel efficiency.
Keep an eye on the brake pad thickness during your annual WOF checks, as the Blazer's weight can lead to gradual wear.
Wash and wax the exterior regularly, especially if you live near the coast, to protect the paint finish from salt spray.
Estimated repair costs if issues arise
Future Budget Planning: Depending on the car's history, you might eventually need to budget for a water pump replacement, which is a standard maintenance item for this engine architecture as it reaches higher kilometres.
Future Budget Planning: If you notice a light knocking sound over bumps, it is common to consider replacing the sway bar links or control arm bushings to restore that 'factory fresh' ride quality.
Future Budget Planning: As the vehicle ages, the battery may require replacement to support the electronic features; we suggest keeping an eye on start-up speed as a good indicator of health.
