Cylinder Heads and Valves

Cylinder heads and valves play vital roles inside your engine. They seal in the pressures of combustion, circulate coolant to maintain proper operating temperatures, and provide superior compression resistance. Cat cylinder heads and valves are built to provide top performance and long life. High-quality materials and controlled manufacturing processes also mean Cat cylinder heads can be remanufactured for a second life.


New Caterpillar cylinder heads and valves are designed and manufactured using high-quality materials and controlled processes to ensure they provide top performance and long life.

Because new Cat cylinder heads and valves are built to these exacting standards, they not only provide a long initial life but can also be remanufactured by Caterpillar for a second life.

Here are some of the highlights of Caterpillar’s strict remanufacturing process for cylinder heads and valves:

  • Each cylinder head is disassembled, cleaned to meet rigid requirements, and 100% inspected. Internal coolant passages vital to proper water circulation are checked for casting debris, ensuring heat is properly dissipated to avoid cracking.
  • Castings are 100% checked for cracks, erosion, or other damage that could cause failure if left undetected.
  • The combustion deck is resurfaced to ensure a tight seal between the cylinder head and engine block to help prevent combustion gas and coolant leaks.
  • Valve springs are tested to ensure that the load limits meet Caterpillar specifications.
  • All exhaust valves and other critical wear and sealing components are replaced with new Caterpillar parts—as are other parts, including head castings, which can’t be remanufactured to demanding Caterpillar specifications.
  • All Reman cylinder heads are pressure-tested for leaks before they leave the factory.


When you need repairs, Cat Reman cylinder heads will get you back to work quickly, reliably, and affordably.

Completely remanufactured using the latest technology and updated to include critical design improvements, Cat Reman cylinder heads offer same-as-new performance, long life, and quick turnaround, all at a fraction of the price of new parts.

In addition, Caterpillar backs Reman cylinder heads with a same-as-new parts warranty.


Remember to return your Cat cylinder head and valve cores in their original cartons.
