Head bolts go in whenever the cylinder head comes off, because the bolts in this set are not reusable. Coolant loss, overheating or white exhaust smoke can come from several causes. Before you replace the bolts, rule out a leaking hose or a weak thermostat, and have a shop confirm the head itself is the problem.
