Replacing the Timing Belt?

Good evening,

I attached the procedure for you of the replacement of the belt. Let me know if you have any other questions. Check out the diagrams (Below).

Removal
1. Disconnect the battery ground cable.
2. Remove the exhaust side spark plugs.

3. Remove the crankshaft pulley.
Remove the bolt.
Remove the crankshaft pulley.

4. Remove the outer timing belt cover.
5. Rotate the crankshaft until the number 1 piston is at Top Dead Center (TDC).

6. CAUTION: If you attempt to remove the belt without loosening both timing belt tensioner adjusting bolt and spring pivot bolt, damage to Camshaft Belt Tensioner Tool could occur when attempting to relieve belt tension.

7. Loosen the timing belt spring pivot bolt. Do not remove.

8. Loosen the adjusting bolt slowly and release spring tension.
9. Rotate tensioner with adjusting tool, against spring pressure, clockwise to the farthest position.
10. Hold in this position and tighten adjusting bolt to hold tensioner away from the belt.

11. Remove the timing chain/belt.

Installation

1. Make sure the crankshaft is at TDC on piston No. 1, with the crankshaft keyway pointing straight up and the circle on crankshaft sprocket aligned with notch in engine front cover.

2. Align the timing marks.
Align the crankshaft sprocket mark to the front cover notch.
Align the oil pump sprocket diamond to the engine front cover diamond.
Align the camshaft sprocket triangle to the engine front cover triangle.

3. Install the timing chain/belt over the crankshaft sprocket, proceeding counterclockwise over the oil pump sprocket and over the camshaft sprocket.

4. Loosen the bolt allowing the tensioner pulley to press against the timing chain/belt.

5. Note: The timing belt tensioner must not be tightened or belt tension will not be distributed over the entire belt.

Rotate the crankshaft two revolutions clockwise. Bring crank slowly to number one position firing position (keyway on crank facing up). The dot on the crankshaft gear is aligned with the notch on the front cover.
6. Recheck timing mark alignment. Repeat if required.
7. Tighten the bolts.

8. Install the crankshaft pulley.

9. Tighten the bolt.

10. Install the outer timing belt cover.
Tighten the bolt.
11. Install the exhaust side spark plugs.

Check out the diagrams (Below). Please let us know what happens.

The inner cover has a triangle for cam and a diamond for the oil pump
And there is a diamond and a triangle stamped into both gears (cam and oil pump) make sure you are using the triangle for the cam and the diamond on the oil pump. Otherwise you have no compression

Make sure you have the timing marks aligned corectly

Verify the valve and ignition timing could be off

Are you getting fuel and spark?

I'd look for a vacuum leak or one of the injectors or more screwing up. Also try chaning the fuel filter as that will screw up the injectors and lean it out as well. Also check the crank and cam sensors for resistance as they will go bad and not give a code. Also check the fuel pressure as that may be out of whack as well.

I still think it's a fuel delivery problem, like an injector screwing up. If you have the "pro type" injector cleaner try that before replaceing injectors or have a ford dealer check your injectors as they can do that. I just find it odd that before the belt broke everything was ok and then now it screws up. Of course the two or three that worked on it before probably aren't telling the whole story as they forget. I still think you ought to check the resistance in the crank and cam sensors as they could be on the high side causing the problem as well.

I looked in the repair manual that is available to me and the resistance isn't shown there either. But if you are getting fuel out of a cylinder while testing then i'd have to say the injector is bad as that 's what goes wrong with them they will either lean out or flood the cylinder. Call a seervice dept at a Ford dealer and see if they can check them it says in the tips that they can to see what's wrong with them. In a worst case you could go to an auto parts and check resistance on a new and see what you have on yours. Same with a cam sensor. Other than that I have no idea what to tell you next.

Recheck the timing marks
make sure u have the correct marks on

Hi Joshwissehr,

Thank you for the donation.

To adjust the tension of the belt, the spring for the tensioner is sufficient. However you need to turn the the engine to compression stroke to get the correct tension.

After installation and everything tightened, turn the crankshaft clockwise at least one revolution to let the belt settle. Slowly turn the crankshaft until compression is felt. Loosen the tensioner and retighten when the spring tension moves the bearing.

Usually around 60 to 100k miles dependiing on your driving.
