21883696 Hexagon Screw | Genuine Volvo Penta Part

🔧 Product Description

This genuine Volvo Penta v8 timing-housing screw is specified for the GM Gen IV V8 engine assembly. The thread, length, strength class and installed position must match the original fastener.

🚤 Compatibility

• Year Range: approximately 2012-2016

⚙️ Key Features

• Timing-housing screw for the GM Gen IV V8 assembly
• Thread, length, strength class and installed position must match the original fastener

🔌 Function

Clamps the timing housing to the engine at the designed load, holding the sealing face tight so the joint stays oil-tight under vibration.

⚠️ Common Signs of Failure

• Oil weeping along the timing-housing joint
• Screw found finger-slack at a service
• Head drive rounded out on removal
• Thread galled, stretched or picked up
• Screw seized or corroded into the block

🛠️ Service Notes

• Check the length, thread and strength grade of the replacement against the screw you removed — engine fasteners are chosen for a specific clamp load, and a longer or softer screw is not a substitute
• Clean the threads in the component and make sure the mating faces are clean and flat before assembly; dirt, paint or old sealant in a joint feels like tightness and leaves the joint loose
• Tighten to the torque figure and the tightening sequence given in the workshop manual for your engine, working up progressively rather than pulling each screw down in one go
• Use thread locking or sealing compound only where the manual calls for it, and renew the locking washer, tab washer or nut that works with the screw
• Renew rather than reuse screws that are corroded, thread-damaged or visibly stretched, and any screw the manual tightens by torque-plus-angle
