V-belt routing for a Chev 454 (7.5l) engine

This is the routing diagram for a 454 engine using v-belts only, not a serpentine belt.
The following abbreviations are used :

C - Crankshaft
S - Smog pump (A.I.R.) system
W/P - Water Pump
Alt - Alternator / Generator
A/C - Airconditioner
P/S - Power steering(In some installations also includes the brake booster pump)

This particular setup is most prevalent in motorhomes. Refer to the diagram.
Diagram 1 is for the first groove on the crank(closest to the block), and utilizes the 1st groove on the power steering.(belt no : 15415)
Diagram 2 is for the 2nd crank groove and utilises the 1st groove on the water pump pulley, the A/C pulley and the 2nd groove on the P/S pulley.(belt no 15590)
Diagram 3 is for the 3rd groove on the crank

If your motorhome uses a serpentine belt it replaces the belt in track number 3. (serpentine belt no : 6K560)
The upper smog pump(not shown in diagrams) is powered from the powersteering (Hydraboost) pulley (V-belt no : 15450)

serpentine belt replacement

2.0L Engines
See Figures 11, 12 and 13
The accessory drive belt for 2.0L engines has no provision for manual belt adjustment, since these engines use an automatic belt tensioner. Drive belt slack is taken up by the automatic tensioner.
Movement of the automatic tensioner assembly during engine operation is not a sign of a malfunctioning tensioner. This movement is the tensioner self-adjusting and is required to maintain constant belt tension.
The belt tensioner has a belt length indicator. If the indicator marks are not between the MIN and MAX marks, the belt must be replaced.
