* Engine Variations: Even within the 5.9 liter Cummins 24 valve family, there are various models and years, each with potentially different torque specifications for the exhaust manifold.
* Component Differences: The specific exhaust manifold you have, along with its mounting bolts and the engine's overall configuration, can influence the required torque.
* Safety: Torque settings are critical for proper assembly and engine function. Incorrect torque could lead to leaks, damage, and even engine failure.
How to find the correct torque setting:
1. Consult your service manual: This is the most reliable source for your specific engine model and year.
2. Look up your engine's specifications: Use your engine serial number and online resources like Cummins' website or a reputable parts supplier to find the correct information.
3. Contact a qualified mechanic or Cummins dealer: They can provide accurate torque specs based on your engine details.
Remember: Always use a torque wrench to ensure the proper tightening of the exhaust manifold bolts. This will help you avoid damaging the engine or causing leaks.
