The cylinder head is an essential engine component. It seals the combustion chambers and houses important engine components.
Main Functions of a Cylinder Head
1. Seals the combustion chamber: Prevents compression and combustion gases from escaping.
2. Houses the valves: Accommodates intake and exhaust valves.
3. Supports fuel combustion: Provides the chamber where the air-fuel mixture burns.
4. Controls airflow: Allows air into the engine and exhaust gases out.
5. Houses camshafts: In many engines, it supports the camshaft and valve-operating components.
6. Cooling: Contains coolant passages that help regulate engine temperature.
Why Must It Be Replaced?
1 Cracks or physical damage.
2 Warping due to overheating.
3 Damaged valve seats.
4 Severe coolant or oil leakage.
5 Irreparable damage to the combustion chamber.
