2.0L I4 (QR20DE)
Petrol
Listen for a metallic rattling or 'marbles in a can' sound during a cold start. | Description: The QR20DE engine is prone to timing chain stretch. Any rattle suggests the tensioner is at its limit, which can lead to expensive engine timing failure.
Execute several low-speed turns and observe the response when shifting from Park to Drive. | Description: Automatic transmissions in these vans work hard. Delayed engagement or harsh shifts often indicate the need for a fluid flush or a failing solenoid pack.
Drive over speed bumps or uneven surfaces at moderate speed. | Description: Suspension bushings, particularly sway bar links and lower control arm bushes, wear quickly on the Como due to the high center of gravity and commercial loads.
Open and close the side sliding door multiple times, checking for smooth travel and a firm latch. | Description: Worn door rollers and latches are common. A door that doesn't stay securely closed or is difficult to operate is a common WOF (Warrant of Fitness) failure in NZ.
Routine oil and filter change using 5W-30 grade; rotate tires to ensure even wear across the front and rear axles.
Inspect and likely replace the air filter and spark plugs; check brake pad thickness and inspect drive belts for glazing or cracking.
Major service including transmission fluid renewal, engine coolant flush, and a detailed inspection of the timing chain tensioner and water pump.
Inspect the valve cover gasket for oil weeping, which can foul spark plug wells on the QR20DE.
Clean the throttle body periodically to prevent 'idle hunting' or stalling issues common with carbon buildup.
Lubricate sliding door tracks and hinges with high-quality lithium grease to prevent motor or roller strain.
Check the radiator plastic end tanks for hairline cracks or discoloration, which indicates imminent failure.
Inspect rear leaf spring bushings and shackles for cracking or excessive play under load.
Estimated repair costs if issues arise
High labor costs due to engine access; critical to prevent complete engine failure.
Preventative measure to avoid overheating the aluminum head of the QR20DE engine.
Includes parts and labor for pressing in new bushings and performing a wheel alignment.
