⚙️ What is Torque?
Torque is a twisting force that determines the rotational power of an engine. It is typically measured in pound-feet (lb-ft).
⚙️ Why is Torque Important?
Applying the correct torque to cylinder head bolts ensures proper sealing of the combustion chamber, lubricant and coolant passages, and prevents air leaks. This is essential for maintaining engine efficiency and durability.
⚙️ How to Properly Torque Cylinder Head Bolts?
Torquing cylinder head bolts requires following a specific sequence, tightening values, and angular measurements. Precise adherence to these steps prevents leaks and bolt damage.
🛠️ Tools Required
Torque Wrench: Used for applying the correct torque.
Goniometer: Used for measuring angular tightening.
🔩 Bolts & Cylinder Head
Cylinder head bolts (also called Torque-to-Yield or Angular Tightening bolts) are single-use only. Reusing or over-tightening them can cause an improper seal or bolt failure.
The cylinder head is a crucial engine component that manages airflow, fuel injection, and houses valves and injectors. It contains more moving parts than any other part of the engine!
Proper torque application is key to ensuring a smooth and reliable engine performance.
