3590908 Cylinder Head Gasket — Cat 3406 C18

This is a cylinder head gasket designed for Caterpillar engines, forming a critical seal between the cylinder head and the engine block. It is manufactured to meet stringent OEM quality standards, ensuring superior sealing performance compared to a worn or damaged gasket that can lead to leaks. Operators may notice a loss of engine power, visible coolant leaks, or white smoke from the exhaust if this gasket fails.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

Initial signs of a failing cylinder head gasket may include coolant loss without visible external leaks or a slight drop in engine performance. If left unaddressed, the problem can progress to internal coolant or oil contamination, leading to severe engine damage. Continued operation risks significant internal component failure due to overheating or lubrication issues.

Installation Tip

Thoroughly clean and inspect the cylinder head and engine block mating surfaces for flatness and damage before installation. Overtightening the head bolts can distort the gasket or damage the block threads.

Service Note

Inspect the cylinder head for flatness and the engine block deck for damage when replacing the cylinder head gasket.
