Belt Routing Configurations for the 6.7L Diesel Ford Engine
The belt routing configuration for Ford’s 6.7L diesel engine varies depending on the alternator system employed. For vehicles manufactured in 2011, there are three distinct belt routing systems: single alternator, dual alternator, and single alternator with A/C compressor.
Single Alternator System (2011)
For the 2011 single alternator system, the belt routing follows this path:
- Crankshaft pulley → Tensioner pulley → Idler pulley → Water pump pulley → Alternator pulley → Crankshaft pulley
Single Alternator System with A/C Compressor (2012-2015)
The belt routing for the single alternator system with A/C compressor is identical to the 2011 single alternator system, with the addition of the A/C compressor pulley after the water pump pulley.
Dual Alternator System (2011-2015)
The dual alternator system employs the following belt routing:
- Crankshaft pulley → Tensioner pulley → Idler pulley → Water pump pulley → Top alternator pulley → Bottom alternator pulley → Crankshaft pulley
Additional Notes to Consider
- All belt routing configurations utilize a double-sided belt.
- Proper belt tension is crucial and should be ensured through correct tensioner tightening.
- For detailed diagrams of each belt routing, refer to the provided PDF document.
Belt Routing for a 2011 F250 with a 6.7 Diesel
The correct belt routing for a 2011 Ford F250 equipped with a 6.7-liter Power Stroke diesel engine is as follows:
- Crankshaft Pulley: Begin at the crankshaft pulley located at the engine’s bottom.
- Tensioner Pulley: Route the belt over the tensioner pulley and release tension by applying pressure to the tensioner lever.
- Water Pump Pulley: Wrap the belt around the water pump pulley.
- Alternator Pulley: Guide the belt over the alternator pulley.
- Power Steering Pump Pulley: Pass the belt over the power steering pump pulley.
- A/C Compressor Pulley (if applicable): Run the belt over the A/C compressor pulley if your vehicle is so equipped.
- Idler Pulley: Direct the belt around the idler pulley.
- Crankshaft Pulley: Finally, loop the belt back over the crankshaft pulley to complete the routing.
Additional Tips
- Correct belt alignment on all pulleys is essential.
- Use a new belt of the correct size and specifications.
- Tighten the tensioner pulley to the proper torque as indicated in the vehicle’s service manual.
- Regularly inspect the belt for signs of wear or damage, and replace it if necessary.
- Following these instructions will ensure optimal serpentine belt operation and prevent potential engine issues.
