1750454 2s5658 Head Bolt Washer Hard — Cat C10

This is a hardened washer designed to distribute the clamping force of a head bolt evenly across the engine block surface. It is manufactured to meet stringent material specifications, ensuring superior durability and resistance to deformation compared to a worn or fatigued washer. Failure is indicated by uneven cylinder head sealing, leading to coolant or oil leaks, or a noticeable drop in engine compression.

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

The first sign of a failing washer is often a slight coolant leak at the cylinder head joint. If ignored, this can progress to oil contamination in the coolant or vice versa, and a gradual loss of engine power due to reduced compression. Continued operation risks significant internal engine damage from coolant ingress.

Installation Tip

Ensure the cylinder head surface and the bolt threads are perfectly clean before installation. Overtightening the head bolts beyond the manufacturer's specified torque can damage the washer and the cylinder head.

Service Note

Inspect the cylinder head gasket and head bolts for any signs of wear or damage when replacing these washers.
