Follow this direct method to locate the serpentine belt on a 2009 Toyota Camry diagram:
Identify Key Anchor Points
The serpentine belt loops around several pulleys. Identify these core components on the diagram:
- Crankshaft Pulley: Large, lowest pulley connected directly to the engine's crankshaft. Central reference point.
- Power Steering Pump Pulley: Found low on the passenger side (left side in engine bay view). Identifiable by the prominent fluid reservoir near it.
- Alternator Pulley: Located mid-to-high on the passenger side (left side in engine bay view).
- Air Conditioning Compressor Pulley: Positioned low on the driver side (right side in engine bay view).
- Tensioner Pulley: Typically an idler/automatic tensioner pulley below the power steering pump.
Trace the Belt Path Using Component Relationships
Find the belt by tracing its path between these components relative to the crankshaft pulley:
- Driver Side Path: Trace from the crankshaft pulley around the outside of the Air Conditioning Compressor pulley (low on driver side).
- Passenger Side Path: Trace from the crankshaft pulley around the outside of the Power Steering Pump pulley (low on passenger side).
- Upper Path: Connect the Power Steering Pump pulley to the Alternator pulley (above/behind it on passenger side).
- Tensioner Anchor: The belt wraps around the Tensioner pulley, positioned between the Power Steering Pump and Alternator pulleys, applying tension. Confirm it pushes on the belt's backside rib.
Confirm Full Routing
The standard routing is:
- Crankshaft Pulley (outer groove) → A/C Compressor Pulley (outer groove) → Idler Pulley (if equipped, driver side near compressor) → Water Pump Pulley (on V6 models, driver side) → Tensioner Pulley (backside ribs) → Alternator Pulley (outer groove) → Power Steering Pump Pulley (outer groove) → Crankshaft Pulley. (Note: Specific idler presence varies by model).
Avoid tracing belt paths wrapping around the rear (engine-side) of pulleys except the tensioner. Most contact the pulley's front outer rim.
