2.0L (RB20DE) - NEO Straight-Six
Petrol
While at a standstill in neutral, gently rev the engine up to 3,000rpm. | Observation: Listen for any hesitation or 'stuttering' in the NEO RB20DE engine response, which could suggest a tired coil pack or aging vacuum lines.
Check the transmission fluid quality. | Observation: While the car is warm, check the ATF dipstick; the fluid should ideally be a bright, translucent red. If it appears dark or smells slightly burnt, keep in mind that the automatic transmission may require a service sooner than expected.
During your drive, navigate over some light bumps or uneven bitumen. | Observation: Listen for any clunks or rattles from the suspension. The C35 platform is getting on in years, and it is quite common for suspension bushings and ball joints to show signs of wear.
Observe the temperature gauge carefully throughout your test drive. | Observation: Ensure the needle stays steady. Given the age of these vehicles, the cooling system components like the radiator or hoses might be reaching the end of their optimal service life.
Usually a great time to check the condition of your alternator and starter motor.
Consider a thorough refresh of cooling hoses and a professional inspection of the steering rack for any play.
Focus on chassis health, checking for any signs of surface rust in the wheel wells or subframe mounting points.
Regularly monitor your engine oil levels, as these RB units appreciate clean oil to keep the VVT system functioning smoothly.
Change the transmission fluid every 30,000 to 40,000km to keep those shifts feeling crisp and comfortable.
Keep an eye on the spark plugs; using the correct NGK iridium plugs often helps the NEO engine idle more consistently.
Ensure your coolant is fresh, as maintaining the correct mix is essential for protecting the alloy components of the RB20 engine.
Periodically inspect the rubber CV boots under the car to catch any small tears before they turn into larger maintenance jobs.
Estimated repair costs if issues arise
As these cars age, the original coil packs can become heat-brittle. If the car develops a misfire under load, you might eventually need to budget for a set of aftermarket or high-quality OEM-style coils.
If the ride feels a bit 'loose' or wanders on the highway, it is a common future budget planning task to replace the control arm bushings. This makes a world of difference to how the Laurel handles on NZ roads.
The plastic end tanks on original radiators can become prone to cracking over time due to repeated heat cycles. Replacing this with an aluminum unit is a great preventative measure.
