This information is critical and getting it wrong can lead to catastrophic engine failure. You must consult the official service manual for your specific year and model vehicle. The torque specs will vary slightly depending on the year and even the specific engine revision.
To find the correct information:
1. Locate your vehicle's service manual: This is often available online from the manufacturer's website or through a repair manual provider. Your VIN number might be required.
2. Look for the engine section: The main bearing cap torque specification will be detailed in the engine rebuild or major overhaul section.
3. Follow the instructions precisely: The procedure almost certainly involves multiple steps, possibly including a sequence of torque values and then angle tightening to ensure proper clamping force.
Using incorrect torque values can strip the threads, damage the engine block, or lead to premature bearing failure. Do not attempt this work unless you have the correct information and the necessary skills. If you're unsure, take your vehicle to a qualified mechanic.
