Dodge Charger 5.7 serpentine belt diagram with routing and pulley locations
Check belt alignment on every pulley before tightening the tensioner. A single rib out of place can cause noise, wear, and eventual failure. Use the diagram as a reference to confirm the routing path matches the factory configuration of the 5.7 HEMI engine.
Begin with the crankshaft pulley, then guide the belt around the water pump, alternator, and power steering pump. Continue by threading it through the idler pulleys and finishing at the A/C compressor. Keep steady tension while routing to avoid slack that makes installation harder.
Apply pressure on the tensioner with the correct tool, slip the belt over the final pulley, and release slowly. Check alignment again on each pulley surface. Spin the pulleys by hand to verify smooth movement before starting the engine. This prevents premature wear and ensures stable performance of all accessories.
Use a belt diagram every time you replace or reinstall the serpentine belt on a Dodge Charger 5.7. It eliminates guesswork and reduces the chance of routing errors that could damage components.
Dodge Charger 5.7 Serpentine Belt Diagram
Follow the diagram that routes the serpentine belt around the crankshaft pulley, alternator, power steering pump, water pump, air conditioning compressor, and tensioner. Place the belt over the crankshaft pulley first, then guide it around each accessory in sequence. Keep the smooth side of the belt against smooth pulleys and the ribbed side against grooved pulleys.
Use the tensioner to release slack before positioning the belt on the final pulley. After installation, confirm that the belt sits squarely in every groove and that no rib hangs outside the pulley track. Misalignment causes premature wear and noise, so double-check the routing path against the factory diagram.
Inspect the belt for cracks, frayed edges, or glazing before reinstalling. If signs of wear are present, replace it rather than reusing. A properly routed belt ensures stable operation of all driven components, reducing the chance of mechanical failure during use.
Serpentine Belt Routing Path for Dodge Charger 5.7
Follow the correct belt path by starting at the crankshaft pulley, which drives all other accessories. From the crankshaft, route the belt up to the A/C compressor and then across to the power steering pump. Make sure the belt sits properly in each groove before moving to the next pulley.
Continue the path from the power steering pump down to the water pump, then guide it around the alternator. The belt should then wrap around the tensioner pulley, which maintains the proper tightness, and finally pass through the idler pulley before returning to the crankshaft.
Check alignment on every pulley to prevent squeaking and premature wear. Use a diagram as a reference while routing, and apply steady pressure on the tensioner to slip the belt into place without forcing it. A correctly routed belt ensures smooth operation of all connected components.
Identifying Pulleys and Components Driven by the Belt
Check the crankshaft pulley first, as it drives the entire system and transfers power to every connected accessory.
Locate the alternator pulley, which receives motion directly from the belt to keep the battery charged and electrical systems powered.
Inspect the power steering pump pulley, positioned on the side of the engine, ensuring smooth steering response under load.
Find the water pump pulley, which circulates coolant through the engine to maintain proper operating temperature.
Note the A/C compressor pulley, responsible for driving the air conditioning system, usually mounted low on the engine block.
Look at the tensioner pulley and idler pulleys, which keep the belt tight and guide it along its routing path without slipping.
- Crankshaft Pulley: Primary driver of all accessories
- Alternator Pulley: Maintains charging system
- Power Steering Pulley: Supports hydraulic steering
- Water Pump Pulley: Circulates engine coolant
- A/C Compressor Pulley: Powers air conditioning system
- Tensioner and Idlers: Keep the belt aligned and taut
Verify alignment and smooth rotation of each pulley during inspection to prevent premature belt wear and accessory failure.
Steps to Replace and Reinstall the Serpentine Belt Correctly
Release tension from the belt by rotating the tensioner pulley with a suitable wrench or serpentine belt tool. Keep steady pressure to avoid slipping and lock the tensioner in the released position if your tool allows it.
Slide the old belt off the pulleys, noting the exact routing path. Use a printed diagram or take a clear photo before removal to avoid confusion during installation.
Inspect each pulley for smooth rotation and check for any wear or damage. Replace faulty pulleys before installing the new belt to prevent premature belt failure.
Route the new belt according to the factory diagram, leaving the tensioner pulley for last. Make sure the belt sits fully in each groove and aligns properly on ribbed pulleys.
Apply pressure on the tensioner again and slip the belt onto the final pulley. Slowly release the tensioner to secure the belt under correct tension.
Double-check alignment across all pulleys. A misaligned belt can squeal, wear quickly, or slip off during operation. Start the engine briefly and watch the belt track smoothly before closing the hood.
