These bolts basically clamp the cylinder head down onto the engine block, creating a really tight seal. They’re high – tension fasteners, meaning they’re designed to be tightened to a specific amount of force. This force isn't just holding things together; it’s critical for keeping the combustion process contained within the cylinders. They’re also designed to withstand a lot of heat and pressure from the engine firing. They’re a fundamental part of the engine’s top end. Without them, you wouldn’t have proper compression, and the engine just wouldn’t run. Everything from coolant to oil relies on that head being sealed correctly, thanks to these bolts. Think of them as acting like a shield between the combustion chamber and everything else. If these bolts stretch, break, or even just come loose, you'll have major problems. You’ll likely notice if one fails – usually with a loss of power, coolant leaking, or even a blown head gasket. Replacing them isn’t something you want to put off. They’re often torque – to – yield bolts, which means they’re designed to stretch a specific amount when tightened and aren't reusable. If you're doing a head gasket job, you pretty much always replace these. You can find a good selection of them over at Fixparts Online, and they'll have the right ones for your engine. Getting the correct bolt is really important – different engines need different strengths and lengths. Buy risk-free: Cylinder Head Bolt (MPN 02950) is covered by a 3 year manufacturer guarantee!
