Drive Belt: Testing and Inspection

DRIVE BELTS:

Checking Drive Belts

WARNING: Be sure to perform when the engine is stopped.

Remove air duct (inlet) when inspecting drive belt for alternator, water pump and A/C compressor.

Remove engine undercover (with power tool) when inspecting power steering oil pump belt.

Make sure that indicator (single line notch) of each auto tensioner is within the allowable working range (between three line notches).

NOTE: Check the auto tensioner indication when the engine is cold.
When the new drive belt is installed, the range should be A.
The indicator notch is located on the moving side of the auto tensioner for alternator, water pump and A/C compressor belt, while it is found on the fixed side for power steering oil pump belt.

Visually check entire belt for wear, damage or cracks.

If the indicator is out of allowable working range or belt is damaged, replace the belt.
