I need a belt diagram for routing because there is no belt on it for reference.

Hi and thanks for using 2CarPros. Com. First, here are the directions for removing and replacing. I have attached pictures which are related to this process.

Ribbed belt - four cylinder gasoline engine, removing and installing:

Caution:
Always replace ribbed belt if found to be faulty. This will avoid related break-downs or operating problems.
If a used ribbed belt is to be reused, mark direction of rotation before removing. When installing used ribbed belts observe the direction of rotation marked on removal. Installing opposite to the direction of rotation leads to belt damage!
It is not necessary to adjust the ribbed belt tension, as a spring loaded tensioner guarantees the best possible belt tension.
Special tools, testers and auxiliary items needed

3090 Rod Support
Removing
Lift vehicle.
Remove screws -arrows- on each side of the insulation cover.
Lower and remove cover.
Remove screw -1-.
Release clips -2-.
Pull insulation cover out from retainer -3-.
NOTE: Do not reuse clips -2-. Always replace after releasing.
2.0L - 4-cylinder normally aspirated engine
Pry out caps -arrows- and release fasteners underneath.
Remove nut -1-.
Pull dipstick out.
Remove engine cover.
1.8L - 4-cylinder turbocharged engine

Continued for all
Mark direction of rotation of ribbed belt if it is to be reused.
Loosen ribbed belt by turning tensioner in direction of -arrow-.
Block tensioner with 3090.
Remove ribbed belt.
Installing

Caution:
When installing ribbed belts that have already been used, please make sure to mark the running direction during removal!
Before installing the ribbed belt, make sure that all subassemblies (generator, a/c compressor etc.) Are securely mounted and turn freely.
When installing belt, ensure correct seating in the belt pulleys!
Install ribbed belt according to routing diagram.
Counter-hold tensioner and remove 3090.
Slowly release tensioner to engage ribbed belt.
Start engine and check belt running.
Install engine cover.
Install center and right (lower) engine covers (noise insulation).

The last two pictures are of the routing. The first is without AC the second with AC.

I hope this helps. Let me know if you have other questions,

Take care,
Joe
