Installation Guide
Completely shut down the engine and allow full cooling before disassembly to avoid scald risk.
Thoroughly clean cylinder head and engine‑block mating surfaces, remove old gasket residues, carbon deposits and burrs.
Inspect new 225‑3099 gasket for cracks, creases or transport damage before mounting. Never reuse old gasket.
Place gasket in correct orientation, fit cylinder head and tighten bolts step‑by‑step strictly according to OEM torque sequence and torque values.
Complete peripheral assembly, refill qualified coolant and engine oil, perform idle trial run, monitor engine temperature and check for all‑joint leakage.
Maintenance Tips
Keep cooling system well‑maintained; avoid sustained engine overheating which is the main cause of head gasket premature failure.
Strictly follow OEM torque procedure and torque sequence for cylinder‑head bolt tightening; uneven torque will lead to incomplete sealing.
Regularly inspect coolant and engine‑oil condition to detect early‑stage gasket failure.
When replacing cylinder head gasket, inspect cylinder‑head flatness; resurface or replace warped cylinder‑head if necessary.
