FSM Installation Protocol & Warnings
⚠️ CRITICAL WARNING (OIL FILTER HOUSING): The 3.6L Pentastar oil filter housing is made of plastic. Do NOT over-tighten the oil filter cap. If you exceed 18 ft-lbs of torque, you will crack the oil cooler housing assembly beneath it, resulting in a massive oil leak and a highly expensive repair. Thread it gently until it seats, then snug it to spec.
