1. Disconnect the negative battery cable.
   
2. Position crankshaft so that No. 1 piston is at Top Dead Center (TDC).
   
3. Remove the splash guard.
   
4. If equipped, remove the cruise control actuator.
   
5. Loosen and remove the power steering pump drive belt.
   
6. Remove the two bolts that attach the top power steering hose to the power steering pump. Cover and seal the hose and the open port of the pump.
   
7. Clamp shut the power steering reservoir return hose, remove it from the return line, and remove the power steering pump and reservoir as an assembly.
   
8. Remove the remaining accessory drive belts. Refer to Section 1 for specific details.
   
9. Place a piece of wood between the oil pan and the jack, support the engine with a jack.
   
10. Remove upper engine bracket.
    
11. Remove the valve cover.
    
12. Make sure the engine is at Top Dead Center (TDC) for No. 1 cylinder. The engine is at TDC for No. 1 cylinder when:
    
    • The white Top Dead Center (TDC) mark on the crankshaft pulley is aligned with the raised pointer.
      
    • The UP marks on both camshaft sprockets are at the topmost (12 O'clock) position.
      
    • The holes in the No. 1 exhaust and intake cam journals align with the holes in the camshaft. A 4.5 mm or 5/32inch drill bit or Allen key can be placed through the holes to prevent the cams from rotating while removing or installing the cam belt.
      
13. Remove the crankshaft pulley. For details, see crankshaft pulley removal in this section.
    
14. Remove the timing belt covers.
    
15. Loosen the adjusting bolt 1/2-1 turn. Release the tension from the belt by pushing on the tensioner, then retighten the adjusting bolt.
    
16. Remove the timing belt.
    

To install:

1. Be sure the timing marks are properly aligned.
   
2. Install the timing belt around the crankshaft sprocket and then stuff a clean rag or paper towel between the belt and the sensor guard to hold the belt engaged with the sprocket teeth.
   
3. Place the flat side of the belt clockwise around the top of the tensioner and then engage the toothed portion of the timing belt counterclockwise around the bottom of the water pump sprocket.
   
4. Carefully pull the timing belt upward but do notmove the crankshaft. If the crankshaft moved, carefully realign the crankshaft timing belt sprocket with the TDC marks. Carefully engage the teeth of the timing belt onto the exhaust camshaft sprocket, but only install the belt about 1/3 of the way onto the sprocket.
   
5. Grasp the timing belt on the toothed side and gently lift the belt enough to begin sliding it onto the intake camshaft sprocket.
   
6. Once the belt has started to slide onto the intake camshaft sprocket, slide the belt equally onto both the intake and exhaust camshaft sprockets.
   
7. Quickly loosen and then retighten the timing belt tensioner bolt.
   
8. Remove the tools from the camshaft caps used for securing the camshafts, and remove the cloth used to keep the timing belt engaged in the crankshaft sprocket.
   
9. Apply a clockwise load on the intake camshaft sprocket bolt to remove any slack between the intake camshaft sprocket, exhaust camshaft sprocket and the crankshaft timing belt sprocket, then loosen and retighten the timing belt tensioner adjusting bolt to allow tension to be applied to the belt.
   
10. Install the crankshaft pulley sprocket/timing belt guide washer.
    
11. Install the lower and upper timing covers.
    
12. Install the crankshaft pulley and tighten the bolt to 130 ft. lbs. (177 Nm).
    
    WARNING

    If any binding is felt when adjusting the timing belt tension by turning the crankshaft, STOP turning the engine, because the pistons may be hitting the valves.
    
    

13. Rotate the crankshaft about 5-6 times counterclockwise to seat the timing belt.
    
14. Position the No. 1 piston to TDC.
    
15. Locate and remove the rubber plug for the timing belt tensioner on the lower timing belt cover.
    
16. Loosen the adjusting bolt 1/2 turn by
    
17. Rotate the crankshaft counterclockwise 3 teeth on the camshaft pulley.
    
18. Tighten the adjusting bolt to 40 ft. lbs. (54Nm).
    
19. Retighten the crankshaft pulley bolt to 130 ft. lbs. (177 Nm).
    
20. Install the valve cover.
    
21. Install the engine mounting bracket, then remove the jack.
    
22. If removed, install the cruise control actuator.
    
23. Install the accessory drive belts.
    
24. Install the splash guard.
    
25. Connect the negative battery cable.
    
26. Check the engine operation and road test.
    

Never allow antifreeze, oil or solvents to come into with a timing belt. If this occurs immediately wash the solution from the timing belt. Also, never excessive bend or twist the timing belt; this can damage the belt so that its lifetime is severely shortened.

I would recommend that you avail yourself of a service manual ( by Chilton, Haynes, etc) unless you feel fairly confident working on this kind of level of repair.
