Cylinder Heads

Maintain Your INFINITI's Engine Performance with Quality Cylinder Heads

Don't compromise with unreliable alternatives when genuine components are within reach. That's where Coulter INFINITI excels. Cylinder heads sit atop your engine block and contain combustion chambers where fuel ignites. These precision-machined components manage airflow and seal combustion pressure. Healthy cylinder heads are essential for power output and fuel economy.

Cylinder Head Operation

Cylinder heads house valves, springs, and camshafts that control air and fuel mixture entering each cylinder. They also route exhaust gases out through ports. The head gasket seals the interface between heads and block, containing combustion pressure. Coolant passages within heads regulate temperature. Models like the Q50 and Q60 feature advanced cylinder heads with variable valve timing systems.

Causes of Cylinder Head Damage

Overheating warps cylinder heads, causing coolant leaks and compression loss. Carbon deposits accumulate on valves and combustion chambers, reducing efficiency. Timing chain or belt failures allow valves to contact pistons, bending valves and cracking heads. Poor maintenance leads to sludge buildup that blocks oil passages. Generic replacement heads lack the precise specifications your INFINITI requires. Genuine heads maintain factory tolerances and include updated engineering improvements.

Replacement Indicators

Replace cylinder heads when compression tests reveal significant pressure loss. External coolant leaks from the head gasket area indicate warpage. Excessive oil consumption or white exhaust smoke suggests internal damage. Your vehicle also depends on quality timing belts to protect cylinder heads from catastrophic damage. Mechanics can perform specialized tests to determine if repairs or replacement make better economic sense.
