1.2L CR12DE Inline-4
Petrol
Listen closely while cold-starting the engine. | Observation: Be mindful of a rattling noise from the timing chain area; in higher-mileage K12s, the chain can stretch, so listen for any unusual ticking that persists after start-up.
Engage the transmission through all gears. | Observation: Pay attention to how the car shifts; if it's the automatic model, ensure the gear changes are smooth rather than hesitant, as these transmissions prefer regular fluid care.
Check the interior plastics and door handles. | Observation: Test every interior handle and window switch; it is common for the plastic internal linkages to wear over time, making them a bit sticky or stiff to operate.
Observe the idle while stationary. | Observation: Ensure the idle is steady and consistent; if the revs fluctuate noticeably, it may suggest the throttle body requires a clean, which is a known area for maintenance as these cars age.
Usually the time to ensure the spark plugs and air filter have been refreshed to keep the 1.2L engine running efficiently.
A good point to inspect the condition of suspension bushings and engine mounts, which naturally soften over many years of NZ road use.
Consider having a specialist assess the timing chain tensioner health if you haven't had a mechanical inspection recently.
Keep a regular eye on the engine oil level between services, as smaller engines often appreciate a quick check every few months.
Change the engine oil and filter every 10,000km to keep that CR12DE heart happy.
Monitor your coolant levels and ensure the cooling system is flushed according to your mechanic's schedule.
Check your tyre pressure regularly, as the Micra is quite sensitive to pressures regarding fuel economy.
Ensure the air conditioning is used periodically, even in winter, to keep the seals lubricated and the system functional.
Estimated repair costs if issues arise
While not guaranteed to fail, if you hear a consistent rattling, you might eventually need to budget for a chain kit replacement. It is a labor-intensive job that involves opening up the front of the engine.
If the idle becomes erratic, the throttle body may have carbon buildup. A clean is affordable, but if the unit itself is faulty, replacing it is the standard fix for long-term stability.
After years on New Zealand roads, you might eventually need to budget for new shock absorbers or control arm bushings if you notice extra knocking or bounce over bumps.
