How to Install a New Cylinder Head Bolt Kit

Model: Ford Focus MK 1 - Years 1998-2004
Part: Engine

This tutorial covers the removal and replacement of the old cylinder head bolts on a Ford Focus. The cylinder head bolts connect the engine block, the head gasket, and the cylinder head. The torque applied to these bolts is crucial for ensuring a perfect seal between the combustion chamber, lubrication channels, cooling system, and the air environment. Before removing them, measure and select the thread size of the bolts. You can then proceed to purchase a new bolt kit. Carefully open the packaging, apply sealant to the ends of each bolt (likely included with the kit), and tighten each bolt using a ratchet with an extension. Use a torque wrench for controlled tightening.

This should be pulled out and thoroughly cleaned with a cloth: once cleaned, reinsert it back into its tube and pull it out immediately after. This way, you can check that the oil mark is between the minimum and maximum levels; finally, you can place the dipstick back in its tube.
