Installation & Maintenance Tips
- Always replace head bolts as a complete set; do not mix old and new bolts on the same cylinder head
- Clean bolt holes in the block and remove oil, coolant and old thread debris before installing new bolts
- Lightly oil the threads and underside of the bolt heads only if specified by the repair manual; follow manufacturer guidance
- Use a calibrated torque wrench and angle gauge to follow the exact torque-and-angle tightening sequence for the B12D1 engine
- Never reuse torque-to-yield (stretch) head bolts; they are designed for single use only
- Tighten bolts in the correct order from the centre outwards to avoid warping the cylinder head
- After the repair, monitor coolant level, oil level and operating temperature carefully to confirm correct sealing
Engine Parts Installation Warning
Cylinder head bolts are critical safety and reliability components. Incorrect lubrication, dirty threads, skipping angles or deviating from the tightening sequence can cause poor clamping, head gasket failure, coolant loss and serious engine damage.
For this reason, head bolts and head gaskets should only be fitted by a suitably qualified and properly equipped workshop that can check head and block flatness, follow the exact torque procedure, and verify that the cooling and lubrication systems are operating correctly after installation.
Engine Parts Return Policy Warning
Engine fasteners and sealing components are sensitive items. Once the inner packaging is opened, bolts are handled, test-fitted or installed, they are no longer considered unused. In line with common supplier policies, opened or fitted engine parts are generally non-returnable unless an incorrect item was supplied and it remains unused, clean and in its original, undamaged packaging.
Please double check your Chevrolet Spark model, year, engine code B12D1 and OE number 96 416 362 before opening the packaging of this head bolt set CB4862. If you are unsure, contact us first so we can help confirm the correct part for your vehicle.
