Welcome to 2CarPros.

The easiest way to do this is to lift the passenger side front of the car, safely support it, and remove the wheel. Once the wheel is off, remove the fender protector. See pic 1. The picture shows the entire inner fender which is known as the fender protector. It is held in with plastic rivets and bolts. Now, to be honest, that is a lot of work. So, you may want to remove enough of it so you can gain access to the belt tensioner which is right above the crankshaft pulley. See picture 2.

Once you access the tensioner, hold the hexagonal part (A) of drive belt auto-tensioner (1) with a wrench securely (see picture 2) then move the wrench handle in the direction of arrow (loosening direction of drive belt auto-tensioner).

Then do the following:

WARNING:
Avoid placing hand in a location where pinching may occur if the holding tool accidentally comes off.
3. Insert a rod approximately 6 mm (0.24 in) in diameter into the hole (B) of the retaining boss to lock drive belt auto-tensioner.
- Keep drive belt auto-tensioner pulley arm locked after drive belt is removed.
4. Remove drive belt.

INSTALLATION

1. Install drive belt.

CAUTION:
- Confirm drive belt is completely set to pulleys.
- Check for engine oil and engine coolant, be sure they are not adhered to drive belt and each pulley groove.
2. Release drive belt auto-tensioner, and apply tension to drive belt.
