After unpacking ProSeries stud bolts, inspect all hardware prior to installation. Look for obvious defects or shipping damage. Contact our sales team immediately with any questions or issues. 2. Before mounting, compare the supplied bolts with the stock screws, paying particular attention to the thread type and length of the bolts. Check existing threads inside engine block for damage. To ensure proper thread engagement and accurate torque readings, make sure that all threads are free from remnant sealer, lubricant, and debris. Check the flatness and surface finish of the engine block and cylinder head deck to avoid gasket failure. 3. Insert stud bolts into the engine block and tighten with a 5mm hexagon socket on the drive provided at the head of the stud bolt with a torque of 15Nm. 4. If the stud bolts are to remain permanently installed in the engine block, they can be used with screw lock (not included) 5. \u003cstrong\u003e\u003cem\u003eAttention!\u003c\/em\u003e\u003c\/strong\u003e Before final mounting of Pro-Series nuts and washers, all contact surfaces must be completely wetted with the supplied special ProSeries lubricant. \u003cem\u003eIf this will not be considered the applied tightening torque is falsified and the resulting clamping force is reduced.
