Tools & supplies (minimum)
- Full metric socket & spanner set (including deep sockets), extensions, universal joint.
- Torque wrench (capable 0–200 Nm) and torque-angle gauge/adapter (if bolts are torque-to-yield).
- Breaker bar.
- Ratchet, impact gun (use carefully, not for final torque).
- Engine hoist or engine support bar (if engine mount(s) must be removed).
- Floor jack + axle stands; wheel chocks.
- Screwdrivers, pliers, hose pliers.
- Gasket scraper / plastic razor blades; brass or nylon brushes.
- Straight edge (1 m or longer) and feeler gauge (for head flatness check).
- Thread chaser or M10–M12 tap (for cleaning head bolt threads in block).
- Soft-faced mallet.
- Drain pans for coolant and oil.
- Clean rags, solvent (brake cleaner), shop vacuum.
- Sealant (manufacturer-approved RTV where required), copper anti-seize, and medium-strength threadlocker (if specified).
- New parts: correct head gasket set (complete set), new head bolts (use new torque-to-yield bolts if specified), valve cover gasket, intake & exhaust manifold gaskets, cam/crank seals if leaking, timing belt/chain kit (belt, tensioner, idlers) and water pump recommended, thermostat, oil & oil filter, coolant, any O-rings/hose clamps disturbed.
- Safety gear: gloves, safety glasses, respirator for solvents if needed.

Safety precautions
- Work on a flat level surface, chock wheels. Support vehicle securely on stands.
- Disconnect battery negative terminal before starting.
- Only work on a cold engine. Drain coolant and oil into proper containers and dispose/recycle legally.
- Support engine when removing engine mounts — failure to do so can drop engine and cause severe injury/damage.
- Do not inhale old gasket debris or solvents; wear eye/hand protection.
- Keep ignition keys away; tag wiring and hoses to avoid mistakes.

Overview (what you’re doing)
Replacing a head gasket requires removing ancillaries and timing components, carefully removing the cylinder head, inspecting surfaces, cleaning, replacing the gasket and bolts, and reassembling to correct torque/timing. Also replace related wear items (timing belt/water pump/thermostat) while the job is open — cost-effective and reduces rework.

Step-by-step procedure
1) Preparation
- Gather workshop manual (model-specific torque values, bolt sequences, timing marks).
- Disconnect battery negative. Label electrical connectors, vacuum lines, and hoses with tape.
- Remove airbox and intake plumbing for access.

2) Drain fluids
- Drain engine oil and coolant into pans. Remove oil filter.
- Remove ancillary belts (alternator, A/C) and accessories that block access.

3) Remove ancillaries and intake/exhaust
- Remove intake manifold and throttle body (label hoses and vacuum lines).
- Remove exhaust manifold/header and heatshield (spray penetrating oil on studs; use correct sockets). Replace exhaust manifold gasket(s).
- Remove engine cover, accessory brackets, alternator, power steering pump (support/leave hoses connected if possible).
- If HVAC compressor prevents removal and you don’t want to disconnect refrigerant, carefully unbolt and hang compressor with wire (do not let hoses carry load).

4) Remove timing components
- Set engine to TDC on cylinder 1. Mark timing positions/photo for reference.
- Remove timing belt/chain covers. Note or photograph sprocket positions.
- If belt-driven, remove timing belt following manual. If chain, follow chain removal procedure.
- Replace timing belt/chain, tensioner, idlers and water pump while accessible. This is highly recommended.

5) Prepare to remove cylinder head
- Remove valve cover(s). Note camshaft positions and mark camshafts if necessary.
- Loosen and remove head bolts in the reverse order of tightening — in several steps (e.g., 10 Nm increments) until finger loose. Do not pry the head off.
- If engine is fitted with timing chain/tensioner, ensure chain is supported before lifting head to avoid dropping cams.

6) Remove head
- Use an engine hoist or have a helper; lift head straight up. Heads can be heavy (and may be stuck due to gasket/sealant).
- Put head on bench on wooden blocks.

7) Inspect head & block
- Inspect head for cracks (especially around valves), check for blown gasket signs: oil in coolant, coolant in oil, combustion leakage marks.
- Clean head and block mating surfaces: remove gasket material carefully with plastic scrapers and solvent. Do not gouge surfaces.
- Use straight edge and feeler gauge to check warpage across head and block mating surfaces (spec from manual). If warpage exceeds spec, head must be machined or replaced.
- Clean head bolt holes in block with thread chaser; blow out debris. Clean head bolt threads if re-using bolts (but generally replace if torque-to-yield).

8) Prepare new components
- Use new head gasket (ensure correct orientation — markings “UP” or cylinder order).
- Use new head bolts if specified (many modern engines are torque-to-yield and must be replaced).
- Replace valve cover gasket and any seals disturbed.

9) Installation — head to block
- Ensure mating surfaces are clean & dry. Place new head gasket on block, aligning dowels.
- Carefully lower the head onto the gasket (straight down).
- Lightly oil bolt threads only if manual specifies (some manuals require dry threads and use threadlocker or anti-seize on specific threads). Follow manual.
- Thread head bolts by hand, then tighten in manufacturer sequence in stages: e.g., 30 Nm, then 60 Nm, then final stage or final angular turns if required. Use torque-angle gauge for angle steps.
- If bolts are torque-to-yield, follow the exact angle procedure — they must be replaced, and you cannot reuse old bolts.

How to use key tools
- Torque wrench: clean threads, set to first stage torque, use correct sequence, apply smooth even pull until wrench clicks. For angle-turns, use torque-angle adapter or marking method to ensure precise degrees.
- Breaker bar: use for initial loosening of tight bolts only; don’t use to tighten to final, use torque wrench.
- Engine hoist/support: attach to head lifting points or cam cover bolts as directed. Lift evenly to avoid bending head.
- Gasket scraper: use plastic or brass to avoid scoring surfaces. Work at low angle.
- Straight edge & feeler gauge: place straight edge across several directions; slide feeler gauge at points to measure highest gap.
- Thread chaser: carefully run down bolt holes to remove corrosion; blow out debris afterwards. Do not use oversized taps.

10) Reassembly (timing & ancillaries)
- Reinstall cam timing components; set timing marks exactly per manual. If you replaced belt/chain, tension correctly.
- Reinstall valve cover with new gasket, manifolds with new gaskets, sensors and all ancillaries. Replace any faulty hoses/clamps.
- Refill with fresh oil and new oil filter. Refill coolant with correct specification/mixture.
- Reconnect battery.

11) Initial start and checks
- Before starting, crank engine without ignition for 10–20 seconds to build oil pressure (or follow manual priming). Check oil pressure gauge.
- Start engine; run at idle. Check for coolant leaks, oil leaks, exhaust leaks, and listen for abnormal noises.
- Monitor coolant temperature and verify heater core flow. Check for combustion gas in coolant (block test) if doubts remain.
- Re-torque head bolts only if manual instructs — many torque-to-yield bolts must not be re-torqued. Some engines require re-check after heat cycles — follow manual.

12) Post-job items
- After 100–500 km, re-check torque on accessible bolts (if manual requires), check coolant & oil levels, check timing belt tension, ensure no leaks. Replace thermostat if you did not earlier and problems persist.
- Dispose of old fluids and parts responsibly.

Common pitfalls & how to avoid them
- Not replacing head bolts: many are single-use torque-to-yield. Reusing them leads to failure. Replace bolts.
- Ignoring flatness: installing a gasket on a warped head causes re-failure. Measure with straight edge; machine head if out of spec.
- Incorrect torque sequence/values or skipping angle turns: causes uneven clamping and leaks. Always follow the manual.
- Poor cleaning: gouging or leaving residue will prevent sealing. Use plastic scrapers and clean thoroughly.
- Forgetting timing marks/correct timing reassembly: results in misfire or engine damage. Photograph and mark before disassembly; use manual.
- Not replacing related wear parts: timing belt, water pump, tensioners are cheap insurance while you’re there.
- Improper bolt lubrication: follow the manual — incorrect lubrication changes torque reading. Don’t guess.
- Not supporting engine when removing mounts: can drop motor and cause injury/damage.
- Not pressure-testing cooling system after job: hidden leaks can wreck the head again.

Replacement parts suggested (minimum)
- Head gasket (engine-specific full set)
- Head bolts (new torque-to-yield set if specified)
- Valve cover gasket
- Intake & exhaust manifold gaskets
- Timing belt/chain kit (belt, tensioner, idlers); water pump
- Thermostat & gasket
- Cam/crank seals (if leaking or age)
- Oil & oil filter
- Coolant (fill)
- Any sensor seals or O-rings disturbed

Estimated time
- Experienced tech: 8–16 hours (depends on engine and complications).
- DIY weekender: 2–3 days or more.

Final notes (no-nonsense)
- Follow the factory workshop manual precisely for torque specifications, bolt sequences, and timing procedures. That is critical.
- Replace head bolts and timing items while you have access. Clean, measure, and don’t rush reassembly.
- If head is warped or cracked, machining or replacement is mandatory — sealing a bad head with a new gasket is a recipe for immediate failure.

No more.
