2.0L SR20DE - Mid-range trim
Petrol
While cruising at a steady speed, listen for any 'hunting' or surging in the RPMs, as the SR20DE throttle body and idle air control valves can sometimes become sticky with age.
Check the 4-speed automatic transmission by shifting from Park to Reverse and then Drive; observe if there is a harsh delay or 'clunk', which might suggest worn engine mounts or internal wear common in older gearboxes.
While driving on an uneven road, listen closely for rattles or clunks from the front suspension, as the W11's control arm bushes and links often wear out after years on New Zealand roads.
Perform a cold start check by opening the hood to inspect for any signs of weeping around the valve cover gasket, a common observation on SR20 engines that can be easily addressed during a service.
Consider a thorough cooling system flush and replacement of the radiator if it hasn't been done, as plastic end-tanks can become brittle.
Plan for a potential replacement of the oxygen sensor to maintain optimal fuel efficiency and ensure the emissions system is running smoothly.
Evaluate the condition of the alternator and starter motor, as these components have likely served their primary lifespan by this point.
Regularly check the oil level, as the SR20 engine is a robust performer that stays happy when kept with fresh, high-quality oil.
Inspect the coolant levels and color periodically to ensure your radiator and hoses remain in good health.
Keep an eye on the power steering fluid levels to ensure the rack continues to operate smoothly and quietly.
Ensure your brake fluid is flushed every two years to maintain that crisp stopping power the Avenir is known for.
Check the air filter at every oil change to ensure your engine is breathing freely and maintaining its fuel efficiency.
Estimated repair costs if issues arise
If the steering feels a bit vague or the ride becomes overly crashy, you might eventually need to budget for refreshing the front control arm bushings. This ensures the car keeps its predictable handling.
Given the age of the vehicle, it's common to consider replacing the radiator and hoses to avoid any unexpected overheating. Think of this as a 'peace of mind' investment for reliable weekend trips.
If you notice a slight hesitation during acceleration, it could be time to replace the spark plugs and potentially the ignition leads. It's a standard part of keeping an SR20 running at its best.
