Cylinder Heads

Keep Your Engine Running Strong with Genuine Cylinder Heads

Have you ever considered the lifespan of your cylinder heads or when they might need replacement? These engine components manage combustion and keep your Nissan running smoothly every day. At Ed Martin Nissan, we know how cylinder heads work and why they eventually need attention. Your Altima and Rogue both depend on properly functioning cylinder heads to deliver the performance you expect.

What Cylinder Heads Actually Do

Cylinder heads sit on top of your engine block and seal the combustion chambers where fuel ignites. They house the valves, spark plugs, and passages that move air and fuel in while pushing exhaust gases out. The combustion process generates extreme heat and pressure, which cylinder heads must contain while maintaining precise seals. Without properly functioning cylinder heads, your engine loses compression and power.

Common Reasons for Cylinder Head Failure

Cylinder heads crack or warp when engines overheat repeatedly or experience sudden temperature changes. The metal expands and contracts during normal operation, but excessive heat causes permanent damage. Bad head gaskets allow coolant to leak into combustion chambers, creating additional problems. Low-quality aftermarket cylinder heads often use inferior metals that fail faster under stress. Genuine Nissan cylinder heads use materials engineered specifically for your engine's demands.

Signs Your Cylinder Heads Need Replacement

Watch for white smoke from the exhaust, which indicates coolant burning in the combustion chambers. Your engine might overheat frequently or lose coolant without visible leaks. Rough idling and misfires happen when cylinder heads lose their seal. Oil mixed with coolant creates a milky substance in the oil cap or radiator. These symptoms require immediate attention to prevent complete engine failure.
