FSM Installation Protocol & Warnings
⚠️ CRITICAL WARNING: The cylinder heads on the 3.6L Pentastar are made of aluminum. The factory service manual explicitly states DO NOT use anti-seize compound on the spark plug threads. Anti-seize acts as a lubricant and will cause you to over-torque the plugs, stripping the delicate aluminum threads.
