Question about 1999 Ford Ranger SuperCab
I need help on how to replace a timing belt on a 99 Ford Ranger.
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.
Best of luck.
