1.4L I4 (TU3)
Petrol
Perform a cold start and inspect the front-right corner of the engine block near the alternator for fresh oil. | Note: The TU3 engine is notorious for external oil leaks from the cylinder head gasket at this specific corner, often dripping directly onto the alternator.
Cycle through all indicator, headlight, and wiper functions multiple times while turning the steering wheel. | Note: Faulty Comm 2000 indicator stalk units are common, leading to erratic indicator behavior, self-cancelling failures, or headlights switching on randomly.
Drive over speed bumps at moderate speed and listen for any knocking, clunking, or creaking from the front end. | Note: Front sway bar drop links and lower control arm bushes wear out prematurely, particularly on uneven New Zealand road surfaces.
Turn the cabin heater on to maximum heat and feel the passenger-side footwell carpets for dampness or a sweet glycol smell. | Note: The heater matrix is prone to leaking coolant into the cabin footwells, which requires a labor-intensive dashboard removal to repair.
Wiggle the steering wheel rapidly while stationary and feel for sudden drops in assistance or a dashboard 'Steering Fault' light. | Note: The electric power steering (EPS) motor on the steering column can suffer from internal solder joints cracking, causing intermittent complete loss of assistance.
Routine engine oil and filter change. Inspect front brake pads and discs for wear. Check for early signs of fluid leaks around the engine bay.
Replace spark plugs, air filter, and cabin filter. Flush brake fluid. Inspect auxiliary drive belt and check suspension bushes.
Critical timing belt and water pump replacement interval. Perform a complete coolant flush and inspect the head gasket thoroughly for leaks.
Inspect the underside of the oil filler cap for a milky emulsion ('mayonnaise') indicating coolant-oil mixing.
Scan the vehicle's ECU for stored fault codes, paying close attention to oxygen sensor or anti-pollution system faults.
Verify the smooth operation of all electric windows and check that the central locking functions from the key fob.
Check the radiator core and plastic header tank seams for hairline cracks or white/green crusty coolant residue.
Confirm the clutch bite point on manual models; a very high pedal indicates an imminent need for a clutch replacement.
Estimated repair costs if issues arise
Highly recommended to address at the first sign of external oil leakage or coolant mixing. Price includes cylinder head skimming and new head bolts.
Preventative maintenance required every 5 years or 80,000km to avoid catastrophic valve-to-piston damage if the belt snaps.
Sourcing and fitting a replacement steering column switch unit. Requires partial steering wheel disassembly and airbag removal.
Requires replacing or specialized reconditioning of the steering column motor assembly when the internal control unit fails.
