Removal and Installation
Removal
Always install tensioner per vehicle manufacturer’s guidelines.
Remove the plastic engine splash shield from right side wheel well.
Locate and take note of the under hood belt routing diagram. If missing, sketch a diagram on a piece of paper for reference to be used later.
To remove the serpentine belt, use a 14mm box end wrench to rotate the tensioner arm in the clockwise direction (Figure 1). Remove serpentine belt.
Note: Be careful that the 14mm wrench is properly positioned on tensioner pulley bolt to allow clearance when tensioner reaches load (end) stop. Otherwise, your hand may be pinched or the tool may be trapped. Never cut or pry belt off while under tension.
Remove the two tensioner mounting bolts (12mm head) and remove tensioner assembly from engine (Figure 2).
