Honda cylinder head bolt set 1.6 i-DTEC 90005-RZ0-G01 – 10 pcs

Genuine Honda cylinder head bolt set 1.6 i-DTEC – 90005-RZ0-G01 (10 pcs)

Genuine Honda cylinder head bolt set 90005-RZ0-G01 designed for 1.6 i-DTEC (N16A) diesel engines. The kit includes 10 new head bolts used for clamping the cylinder head to the engine block in modern Honda diesel engines, where correct and even clamping force is crucial for head gasket sealing and long-term reliability.

Why replace the cylinder head bolts?

In 1.6 i-DTEC engines the head bolts are torque-to-yield type, working under very high thermal and mechanical load. For this reason it is strongly recommended to replace the complete set every time the cylinder head is removed – for example when changing the head gasket, resurfacing the head or doing a major engine rebuild. New head bolts help to:

• ensure even clamping force across the whole head gasket surface,
• reduce the risk of combustion gas leaks between cylinders or into the cooling system,
• maintain factory performance and durability of the 1.6 i-DTEC engine.

FAQ – Honda 90005-RZ0-G01 cylinder head bolt set

Can I reuse the old head bolts?
In 1.6 i-DTEC engines the head bolts are torque-to-yield. Reusing them after removal is not recommended – always install a new complete set to avoid loss of clamping force and potential head gasket issues.

Does this kit fit all 1.6 i-DTEC engines?
This set is intended for N16A series engines (N16A1, N16A2, N16A3, N16A4) used in Civic, CR-V and HR-V models listed above. If in doubt, please confirm by VIN.

Do I need specific torque values and tightening sequence?
Yes – cylinder head bolts must be tightened according to the Honda workshop procedure (moment + angle stages). Always follow the official service manual or verified technical data for your exact model and engine code.
