What to look out for

The checks worth doing on a Toyota Celica before you hand over any money. Every documented fault is listed below, each with its own page.

  • Costly issue

    With engine cold, inspect the lower radiator tank seam for cracks or coolant staining.

    See why

    Radiator lower tank cracking and coolant loss (ZZT231)

    The ZZT231 Celica uses a plastic-tanked aluminium core radiator. The lower plastic tank develops cracks at the crimped joint with the aluminium core after approximately 10–15 years, leading to coolant seepage and eventually a significant leak. The failure is accelerated by pressure cycling and the high underbonnet temperatures associated with the 2ZZ-GE. Coolant loss causes overheating and risks head gasket damage, particularly serious given the existing oil consumption vulnerabilities of the 2ZZ-GE.

    What you would notice

    • Coolant level dropping requiring periodic top-up
    • Small puddle under front of car after parking
    • White crusty residue around the lower radiator tank seam
    • Temperature gauge rising in traffic

    Typically $350–$900 to put right.

  • Costly issue

    Inspect the boot for splitting.

    See why

    Front Lower Arm Ball Joint Wear

    Front lower arm ball joints wear causing clunking and handling imprecision on the lightweight Celica.

    What you would notice

    • Clunking from front suspension over bumps
    • Imprecise handling feel when cornering

    Typically $300–$700 to put right.

  • Costly issue

    Check for pulling under braking.

    See why

    Brake Caliper Guide Pin Seizure

    Front brake caliper guide pins seize from corrosion causing uneven pad wear.

    What you would notice

    • Vehicle pulling to one side under braking
    • One front disc hotter than the other after moderate use

    Typically $150–$500 to put right.

  • Common issue

    Drive over rough surfaces at low speed and listen for rattle from the steering rack area.

    See why

    Electric Power Steering Rack Rattle

    EPS rack develops internal rattle at low speeds over rough surfaces. Common on higher-mileage examples.

    What you would notice

    • Knocking or rattling from steering rack at low speeds
    • Vibration through steering wheel during slow manoeuvring

    Typically $600–$2,200 to put right.

  • Common issue

    Inspect rear trailing arm bushes for cracking.

    See why

    Rear Suspension Trailing Arm Bush Collapse

    Rear trailing arm bushes harden and collapse causing rear knocking and toe changes.

    What you would notice

    • Knocking from rear over rough surfaces
    • Rear toe change and instability at highway speed

    Typically $300–$800 to put right.

  • Worth checking

    Inspect the lower hatch corners and glass seal, check the boot floor for water ingress, and probe spoiler mount holes for rust.

    See why

    Rear hatch and tailgate corner corrosion

    The Celica hatch develops rust in the lower corners and around the glass seal and spoiler mounts as the seal ages and traps moisture, leading to bubbling paint and perforation at the bottom edge of the tailgate.

    What you would notice

    • Paint bubbling on lower hatch corners
    • Rust around hatch glass seal
    • Damp boot area
    • Corrosion near spoiler mounting points

    Typically $300–$1,500 to put right.

07Front strut mount bearing failure — steering click

petrol1999–2006Suspension
CommonSuspension $260–$720 to fix

The upper strut mount thrust bearing on ZZT231 models wears and corrodes over time, accelerated by NZ road conditions, wet weather exposure, and the age profile of these imports. A worn bearing causes the strut to bind when the wheel is steered under suspension compression, then release suddenly over a bump, producing a distinct single or repeated click from the front suspension. In advanced cases the bearing can seize, causing the strut body to rotate with steering inputs and damaging the strut top mount. Replacement is straightforward and inexpensive but frequently deferred.

Symptoms to notice

  • Single or repeated clicking or clunking from front corner when driving over bumps with steering turned
  • Creaking or notchy resistance when turning the steering wheel at parking speed
  • Steering return to centre feels stiff or notchy rather than smooth
  • Noise more pronounced in cold weather

What to check

With the car stationary, turn the steering wheel from lock to lock while listening and feeling for grinding or notchiness transmitting up through the wheel — binding indicates a worn bearing. Drive the car over a speed bump or rough road surface with the wheel at a slight steering angle and listen for clicks from each front corner. Visually inspect the strut top mount area for corrosion, cracking of the rubber isolator, or signs of movement.

Where to look: Front strut upper mount thrust bearing, driver and passenger front corners inside the engine bay at the strut tower

Parts involved: Shock absorber / strut.

Ask the seller

  • “Has the front end ever clicked or clunked when going over bumps with the wheel turned?”
  • “Have the front strut upper mount bearings been replaced?”
  • “When were the front struts last inspected or serviced?”
  • “Has the car passed a WOF with no suspension advisories recently?”

012ZZ-GE excessive oil consumption from piston ring design

Check oil level and ask how frequently it needs topping up.petrol1999–2006EngineRead the full fault: symptoms, where to look, what to ask the seller

022ZZ-GE VVTL-i Lifter Snap at High RPM

Ask about any history of high-rpm use, track days, or loss of the VVTL-i engagement.petrol1999–2006Engine
OccasionalEngine $1,500–$6,000 to fix

Can't confirm for this car

The ZZT231 Celica 2ZZ-GE 1.8 VVTL-i engine uses a secondary lobe lifter that physically snaps under the high-lift cam at 6200rpm. These lifters can fracture when operating under sustained high rpm, allowing a broken fragment to circulate through the engine and cause catastrophic damage to the cam, head, and piston crowns. This is a known documented failure on the 2ZZ-GE and must be checked on any high-mileage example.

Symptoms to notice

  • Sudden loss of high-rpm VVTL-i engagement click at 6200rpm with significant power loss above 6000rpm
  • Metal contamination visible in engine oil on the dipstick or in a fresh oil drain

What to check

  1. Ask about any history of high-rpm use, track days, or loss of the VVTL-i engagement.
  2. Check engine oil for metal contamination.
  3. Run engine to 6200rpm with consent and feel for the VVTL-i engagement click — failure to engage indicates the lifter has already snapped or is stuck.

Where to look: 2ZZ-GE cylinder head, VVTL-i secondary lifter on each exhaust and intake cam lobe

Ask the seller

  • “Has the 2zz-ge vvtl-i lifter snap at been inspected or repaired?”

042ZZ-GE VVTL-i cam actuator oil screen blockage

Scan ECU for P1349 and any VVTL-i related codes before purchase.petrol1999–2006EngineRead the full fault: symptoms, where to look, what to ask the seller

052ZZ-GE VVTL-i oil pressure switch premature failure

Scan the ECU for all stored and pending VVTL-i and VVL related fault codes including P1349 and related codes.petrol1999–2006Engine
OccasionalEngine $200–$650 to fix

Can't confirm for this car

The dedicated oil pressure switch that signals the ECM when sufficient hydraulic pressure exists to safely actuate the VVTL-i high-lift cam mechanism can fail open or closed. A switch failed in the closed position causes the ECM to command high-lift cam engagement prematurely below the designed 6200 rpm threshold, producing a surge or hesitation at unexpected RPM and potentially causing VVTL-i related fault codes. A switch failed open prevents lift engagement entirely, confining the engine to its low-lift power curve and suppressing the secondary power surge. Switch failure is distinct from but often confused with the cam actuator oil screen blockage.

Symptoms to notice

  • Unexpected surge or hesitation at RPM below the normal 6200 rpm cam-lift threshold
  • No secondary power surge above 6200 rpm despite engine otherwise running cleanly
  • Check engine light with VVTL-i or VVL system fault code stored
  • Erratic behaviour of the cam-lift transition on repeated test drives

What to check

Scan the ECU for all stored and pending VVTL-i and VVL related fault codes including P1349 and related codes. Inspect the switch electrical connector for corrosion or water intrusion. Differentiate from actuator screen blockage by confirming oil pressure is adequate and the screen is clean. If a workshop inspection is possible: Use a live data scan tool during a test drive to monitor the oil pressure switch signal state as RPM rises through the 6000-6500 rpm transition range and confirm it switches correctly.

Where to look: Cylinder head, VVTL-i oil pressure switch mounted adjacent to the camshaft actuator on the intake side

Ask the seller

  • “Has the car been scanned for VVTL-i or VVL fault codes recently?”
  • “Does the engine feel like it gains a strong second surge of acceleration above 6000 rpm?”
  • “Has the VVTL-i oil pressure switch been tested or replaced?”
  • “Has the cam lift behaviour changed or become inconsistent?”

066-speed C60 clutch and third-gear synchro wear

On a test drive shift quickly through the gears feeling for synchro crunch and check clutch engagement point and any slip under load.petrol2000–2006Transmission
OccasionalTransmission $800–$2,200 to fix

Can't confirm for this car

The C60 6-speed in the GT/SX wears clutches early with spirited driving and can develop worn synchros, most often on 2nd and 3rd, giving a crunch on quick shifts. Clutch judder and high bite point indicate imminent replacement.

Symptoms to notice

  • Crunch shifting into 2nd or 3rd
  • High or vague clutch bite point
  • Clutch slip under acceleration
  • Judder when pulling away

What to check

On a test drive shift quickly through the gears feeling for synchro crunch and check clutch engagement point and any slip under load.

Where to look: C60 gearbox and clutch

Parts involved: Clutch.

Ask the seller

  • “Has the clutch been replaced and when?”
  • “Does it crunch on fast 2-3 shifts?”
  • “Any gearbox rebuild history?”

01Head gasket failure — ST205 GT-Four (3S-GTE turbo)

Check oil filler cap for mayonnaise-like emulsion.petrol1993–1999EngineRead the full fault: symptoms, where to look, what to ask the seller

02AWD centre differential clutch pack wear (ST205 GT-Four)

On a wet or gravel surface, the AWD should pull evenly — excessive understeer suggests centre diff wear.petrol1994–1999Transmission
OccasionalTransmission $2,500–$7,000 to fix

Does not apply

The ST205 Celica GT-Four uses a viscous-coupling centre differential and front/rear torque-split system. The centre differential clutch packs wear progressively, causing the AWD system to default toward understeer and reduced traction on loose or wet surfaces as the coupling loses its ability to transfer torque to the front axle. Worn centre diff is difficult to diagnose without a proper four-wheel rolling road or drive on varying surfaces. The condition is common on cars with high mileage or that have been driven hard on track. Rebuild or replacement involves significant disassembly of the transmission tunnel.

Symptoms to notice

  • Understeer on loose or wet surfaces that was not previously present
  • Clunking or shuddering during low-speed turning with AWD engaged
  • Uneven tyre wear front vs rear
  • Transmission fluid contaminated with clutch material (metallic sheen)

What to check

On a wet or gravel surface, the AWD should pull evenly — excessive understeer suggests centre diff wear. Ask about any shudder or binding in tight turns at low speed. If a workshop inspection is possible: Check transmission/differential fluid for metallic particles (drain a small sample).

Where to look: Centre differential located within transmission tunnel behind gearbox.

Parts involved: Differential, Clutch.

Ask the seller

  • “Has the transmission/differential fluid been changed recently?”
  • “Does the car shudder or bind in tight car-park turns?”
  • “Has the AWD system ever been serviced or the centre diff rebuilt?”

031ZZ-FE Oil Consumption from Piston Ring Wear

Check oil level frequently.petrol2002–2006Engine
CommonEngine $500–$3,000 to fix

Does not apply

The 1ZZ-FE 1.8 in the ZZT230 Celica consumes oil at elevated rates from piston ring wear and valve stem seal degradation on high-mileage examples. Oil consumption above 1 litre per 5000km is abnormal.

Symptoms to notice

  • Blue smoke from exhaust on startup and deceleration
  • Frequent oil level top-ups needed between regular service intervals

What to check

Check oil level frequently. Blue smoke from exhaust on startup after overnight park indicates valve stem seal or ring wear. Oil consumption above 1 litre per 5000km is abnormal.

Where to look: 1ZZ-FE engine cylinder bores, piston rings, and valve stem seals

Ask the seller

  • “Has the 1zz-fe oil consumption from piston been inspected or repaired?”
