You MUST consult your vehicle's repair manual or a reliable source like a factory service manual. These manuals will provide the correct torque specification based on the specific parts used on your truck. Using an incorrect torque value can lead to damage to the harmonic balancer, crankshaft, or other engine components.
Attempting to find this information online without a specific part number risks getting inaccurate information that could damage your engine. A generic number found online is unreliable and potentially dangerous. Always prioritize using the correct information from a reputable source.
