Cylinder Heads

Protect Your Engine with Quality Cylinder Heads

At Findlay Nissan Henderson we understand the importance of keeping your cylinder heads in good condition. Cylinder heads seal the combustion chambers and house critical components that make your engine run properly. We carry genuine Nissan cylinder heads engineered specifically for your Armada and Quest. Aftermarket cylinder heads may look similar but often use metals that can't withstand the extreme temperatures and pressures your engine generates daily.

What Cylinder Heads Actually Do

Cylinder heads bolt onto the top of your engine block and create sealed chambers where fuel combustion occurs. They contain the intake and exhaust valves that control airflow through the engine. Inside the heads, passages channel coolant to regulate temperatures while other pathways route oil for lubrication. The combustion process creates intense pressure and heat that cylinder heads must contain reliably. Each head also positions spark plugs precisely for efficient fuel ignition. Modern designs incorporate complex port shapes that optimize airflow for better performance.

Why Cylinder Heads Eventually Fail

Repeated heating and cooling cycles cause metal fatigue that can lead to cracks over time. Engine overheating from cooling system failures warps cylinder heads, destroying their sealing surfaces. Corrosion from contaminated coolant eats away at internal passages and weakens structural integrity. Generic aftermarket heads frequently use casting processes that leave internal flaws prone to premature failure. Poor maintenance practices like ignoring coolant changes accelerate deterioration significantly. Detonation from low-quality fuel can physically damage cylinder head surfaces.

Knowing When Cylinder Heads Need Replacement

White exhaust smoke indicates coolant burning in the combustion chambers from cracked heads. Persistent overheating despite a functioning cooling system suggests warped sealing surfaces. Oil contamination in the coolant reservoir points to internal head cracks. Compression tests showing low readings across multiple cylinders often indicate head gasket or head failure. Replacing damaged cylinder heads along with timing belts during major engine work prevents future problems.
