Answer 2

Ok … I just got finished, and the truck runs great after all the work.

First, disconnect the battery, and remove.

Next, drain the antifreeze, and remove the fan bolts (10mm) with wrench. You will also use the 10 mm to remove the two bolts on each side of the fan cover, and the two bolts that hold the radiator into the truck. Remove all of the above and place aside.

Next, remove the serpentine belt and place aside. The water pump pulley should come off with the belt.

Next, use a 13mm deep socket and remove the 4 bolts on top of the A/C compressor. NEXT, use a 6mm wrench to remove the bracket that holds the a/c line in place on the front of the engine. Remove the a/c wire from the front of the compressor. Know you can safely, and slowly, move the a/c compressor to the front of the vehicle.

Using the same 13mm socket, remove the bolt that you found under the a/c compressor. Look down and to the right of the bolt that you just removed, and you will see two more bolts. Both are 13mm. Easiest way that I found was to go under the driver side tire well, and use 3/8 extensions to reach the two bolts. Once removed, the bracket and the Power Steering pump should be moved to the driver's side of the frame, and the a/c placed on top of the p/s assy.

Remove the bolts (6mm) that hold the timing belt cover in place. Gently work your way around the cover, and push the tabs in to remove the cover.

Use an impact wrench and 7/8 SAE socket to remove the crankshaft pulley. A SOCKET WRENCH WILL NOT WORK. Once removed, gently tap the pulley with a 2x4 (yes the wooden board) to remove. If you have a gear puller, use that. I don't own one.

Remove the old belt. Now for the alignment. Crank - sprocket on bottom. Use the bolt you removed, and a ½ drive wrench, with the 7/8 socket to turn the crank. Once the keyway is at high noon, leave it alone. Next, move the oil pulley sprocket until the diamonds are aligned. This should put the oil pulley at high noon, also. The camshaft should have a diamond and a triangle. The diamond should go to high noon, and the triangle should align with a triangle on the plastic behind the sprocket. YOU SHOULD REALLY CONSIDER CLEANING THE ENTIRE AREA BEFORE ALIGNING THE SPROCKETS. You cannot align the camshaft without locating the two index (triangle and diamond) marks.

You will also notice a tensioner for the timing belt. You will need to loosen the tentioner with a 13mm and 17mm wrenches. Loosen, then use a cheeter bar bar to move the tentioner over. Lock in place by tightening the tentioner bolts. Place the belt on the crankshaft, move to the oil pulley, then to the cam pulley. Release tentioner, then check the alignment. If correct, reverse the above removal plan, and you should be good.

Don't buy the Haynes manual. I fought with the instructions for this project, and the picture for the timing belt project doesn't show the two indexes for the cam sprocket.

Also, while you are doing this, you should replace the antifreeze if you haven't in the past two years.

To replace the timing belt on a 92 Ford Escort you:

1. Disconnect the negative battery terminal.

2. Remove the accessory drivebelt.

3. Remove the drivebelt tensioner and take the tensioner off.

4. Put a jack under the oil pan with a block of wood separating the two.

5. Jack the engine up just enough to take the load off of the top motor mount.

6. Take the motor mount off.

7. Take the timing cover off.

8. Hold the crankshaft pulley with a strap belt and take the bolt off.

9. Rotate the engine clockwise until the timing mark on the camshaft pulley is aligned with the one on the cylinder head and the crankshaft pulley is aligned with the TDC mark on the oil pump housing.

10. Loosen the timing belt tensioner bolt, pry the tensioner to one side and retighten the bolt to hold the tensioner in place.

11. Remove the spark plugs.

12. Remove the splash shields in the fender well.

13. Remove the timing belt.

14. Some models had square teeth and some rounded teeth.

15. Check the old belt for type of teeth.

16. Check the idler pulley.

To Install a new belt:

17. Starting at the crankshaft, install a new belt in a CC direction on the pulleys.

18. Be sure to keep the belt tight between the crankshaft and the camshaft while installing it over the remaining pulleys.

19. Loosen the belt tensioner bolts so the tensioner snaps into place against the belt.

20. Install the crankshaft pulley and tighten to 90 ft. lbs.

21. Rotate the crankshaft 2 complete turns clockwise and stop on the second revolution at the point where the crankshaft sprocket returns to the TDC position. Verify that the camshaft sprocket is also at TDC. IF it isn't the belt has jumped a tooth and the installation procedure must be done again.

22. Tighten the cam tensioner bolt to 80 ft. lbs.

23. The remainder of the installation is the reverse of the removal steps.

Answer 4

The 1991 Toyota Celica GT has a freewheeling engine. Should the timing belt break or stretch past its usefulness, there is little chance that the valves could hit the pistons and cause major engine damage. The manufacturer recommends you change the GT's timing belt every 60,000 miles. You need a special tool to complete the procedure, and it is available through the Toyota dealer. It takes approximately five hours to change the timing belt in the Celica GT.

1. Step 1

   Disconnect the battery's ground cable and lay the cable aside. Jack up the Celica GT and support it with jack stands. Remove the engine splash guard and the intercooler using the appropriate sockets. Remove the accessory drive belt by loosening the tensioner and removing tension on the belt.

2. Step 2

   Remove the alternator and its bracket using the appropriate socket and wrench. Remove the right front wheel using the lug wrench. Remove the right fender apron shield using the appropriate size socket.

3. Step 3

   Place the block of wood on the floor jack. Support the engine with the floor jack by jacking it up just until it touches the bottom of the engine. Remove the right engine mount and the mount bracket using the appropriate sockets. Remove the upper timing belt cover.

4. Step 4

   Turn the crankshaft clockwise until the timing marks on the crankshaft and the camshaft line up. If the marks do not line up the first time around, turn the engine again, and the marks should line up. The crankshaft mark is at 11 o'clock and the camshaft timing marks are at 12 o'clock.

5. Step 5

   Remove the auto tensioner securing bolts and the auto tensioner using the appropriate sockets. Remove the crankshaft pulley bolt using the appropriate socket. Remove the pulley using the special tool #09213-31021. Remove the lower timing belt cover and the belt guide washer. Remove the tensioner pulley retaining bolt and the tensioner pulley using the appropriate sockets. Remove the timing belt. Check the tensioner pulley to make sure it rotates smoothly. If not, replace the tensioner pulley.

6. Step 6

   Install the tensioner pulley and tighten the bolt to 38 foot-pounds of torque. Inspect the auto tensioner for oil leakage. If it leaks, replace it. Press the pushrod against a hard surface. If you can move the pushrod, replace the auto tensioner. Measure the pushrod where it exits the auto tensioner. If the measurement is not between .34 and .37 inches, replace it.

7. Step 7

   Install the timing belt, starting at the crankshaft sprocket and oil pump sprocket (at the same time) and working counterclockwise around the guide pulley and pulley. Install the belt guide washer and the timing belt lower cover.

8. Step 8

   Install the crankshaft pulley and the crankshaft pulley bolt. Tighten the crankshaft pulley bolt to 80 foot-pounds of torque. Check the crankshaft timing mark to ensure it is still aligned. The notch in the pulley should line up with the zero mark on the timing scale printed on the block.

9. Step 9

   Install the timing belt around the camshaft sprockets and behind the tensioner pulley, keeping the timing belt tight on the non-tensioned side (right side while facing the engine).

10. Step 10

    Push the pushrod in the auto tensioner using a vise or press. Insert an Allen wrench through the hole in the body of the auto tensioner and into the hole in the pushrod once they line up to hold the pushrod in place. Tighten the tensioner pulley bolt to 13 foot-pounds of torque. Install the auto tensioner. Tighten the bolts just enough to hold it in place. Leave the torque wrench on the bolt, ensuring that the handle lines up with the camshaft sprocket.

11. Step 11

    Turn the crankshaft clockwise 5/6 of a turn, aligning the crankshaft pulley mark (the pointer mark, not the notch mark) with the 60-degree BTDC mark on the timing cover.

12. Step 12

    Loosen the auto tensioner bolts. Insert the 0.75-inch feeler gauge between the auto tensioner's body and the tensioner pulley bracket. Hold the tensioner in place and tighten the auto tensioner bolts to 15 foot-pounds of torque. Remove the feeler gauge, the Allen wrench and the torque wrench from the tensioner pulley bolt.

13. Step 13

    Turn the crankshaft clockwise for one turn, lining up the crankshaft pulley mark (the notch, not the pointer) to the 60-degree BTDC mark on the timing cover. Measure the distance between the auto tensioner body and the tensioner pulley bracket with the feeler gauges. The measurement needs to be between 0.071 and 0.087 inches. If the clearance is incorrect, repeat the entire timing belt installation procedure.

14. Step 14

    Turn the crankshaft clockwise 2 1/6 turns until the No. 1 cylinder is at top dead center. To ensure the No. 1 cylinder is at top dead center, insert a long screwdriver into the spark plug hole while turning the engine. When you feel the piston come up to the top of the bore, the cylinder is at top dead center. Check that the timing marks are still lined up. Install the rest of the parts in reverse order of removal.
