1. Ensure engine is cool – Allow the engine to cool completely before disassembly
2. Disconnect battery – Always disconnect the negative terminal before working
3. Drain coolant and oil – Drain the cooling system and engine oil to prevent spills
4. Remove the cylinder head – Disconnect manifolds, timing components, and head bolts; lift the cylinder head off the block
5. Clean all mating surfaces – Thoroughly clean the cylinder head and block decks; remove all old gasket material, oil, and debris
6. Check surface flatness – Inspect both surfaces for warpage using a straightedge; resurface if necessary. Maximum warpage limit is 0.05 mm (nominal) / 0.20 mm (limit)
7. Install new head gasket – Position the new gasket on the block deck with the correct orientation (usually marked "TOP" or "FRONT")
8. Install cylinder head – Carefully position the cylinder head on the gasket; align with dowel pins
9. Use new head bolts – If torque-to-yield (TTY) head bolts are specified, always use new bolts
10. Torque in sequence – Tighten head bolts in the correct sequence and stages per manufacturer specifications
11. Reassemble engine – Reinstall manifolds, timing components, and other removed parts
12. Refill fluids – Fill with correct engine oil and coolant mixture (50/50 antifreeze/water)
13. Bleed cooling system – Start engine and bleed air from the cooling system per manufacturer procedure
14. Check for leaks – Inspect for oil or coolant leaks around the cylinder head area
15. Road test – Test drive to verify proper engine operation and no overheating
