    That is a job if you have never done it & don't have aTiming Chain & Belt Manual of professional quality, orinstructions with the new belt,you should have a repair shop perform the workThat said, get the proper reference material before youstart & check as to any tools you may need, to hold the cams,etc.If your not sure about TDC/BDC etc, then you don't have basic mechanical engine knowledge to get involved

Here are the instructions to replace the belt which are ones the same as the 2.3 earlier engine.
Getting Started

  • Remove the radiator shroud and loosen the water pump pulley bolts. Remove the accessory drive belts. Remove the water pump pulley bolts. Remove the water pump pulley and the radiator cooling fan. Drain and recover the Freon from the air-conditioning system. Remove the air-conditioning compressor.
    Remove the power steering pump but leave the lines attached and move aside. Remove the air conditioning bracket. Remove the crankshaft pulley bolt and the pulley using the wheel puller. Remove the timing belt cover.
Align Crankshaft and Block
  • Turn the crankshaft clockwise until the keyway on the crankshaft sprocket is straight up and the dot to the right side of it is lined up with the corresponding mark on the block. Check that the triangle mark on the camshaft sprocket lines up with the same type mark on the block at the 5 o'clock position. If not then turn the crankshaft one more time and it will align.
Loosen Tensioner
  • Loosen the large bolt on the top of the tensioner and then loosen the bolt closest to the tensioner pulley. Use the special ford tool and turn the tensioner clockwise to take the tension off of the timing belt and tighten the adjusting bolt lightly to hold it out of your way. Remove the timing belt.
Work Counterclockwise
  • Install the new timing belt starting on the right side and work counterclockwise. The circle on the crankshaft sprocket and the diamond marks on the oil pump and the triangle marks on the camshaft sprocket should always stay lined up. Loosen the adjuster bolt on the tensioner and rotate the engine two turns clockwise and realign the timing marks. Tighten the tensioner-adjusting bolt next to the tensioner pulley and then pivot bolt. Install the rest of the components in the reverse order that they were removed and tighten the crankshaft bolt to 121 foot-pounds of torque.

SOURCE: Timming belt replacement Ford 2001 dual cam

You have to leave all of the slack at the tensioner. Get the timing marks lined up on both of the cams and the crank. With the slack left at the tensioner, release the tensioner. It is okay if the marks move a little after this. Manually turn the engine crankshaft twice and then MAKE SURE THE MARKS LINE UP! If they do after two revolutions of the engine, you are good to go. This applies wether or not you are at DTC or not! Remember that!

SOURCE: Timing marks on 1999 Ford Ranger 2.5L.

Rotate the engine so that No. 1 cylinder is at TDC on the compression stroke. Check that the timing marks are aligned on the camshaft and crankshaft pulleys. An access plug is provided in the cam belt cover so that the camshaft timing can be checked without removal of the cover or any other parts. Set the crankshaft to TDC by aligning the timing mark on the crank pulley with the TDC mark on the belt cover. Look through the access hole in the belt cover to make sure that the timing mark on the cam drive sprocket is lined up with the pointer on the inner belt cover.

  1. Loosen the alternator retaining bolts and remove the drive belt from the pulleys. Remove the water pump pulley.
  2. Loosen and position the power steering pump mounting bracket and position it aside.
  3. Remove the four timing belt outer cover retaining bolts and remove the cover. Remove the crankshaft pulley and belt guide.
  4. Loosen the belt tensioner pulley assembly, then position a camshaft belt adjuster tool (T74P-6254-A or equivalent) on the tension spring rollpin and retract the belt tensioner away from the timing belt. Tighten the adjustment bolt to lock the tensioner in the retracted position.
  5. Remove the timing belt.

To install:
  1. Install the new belt over the crankshaft sprocket and then counterclockwise over the auxiliary and camshaft sprockets, making sure the lugs on the belt properly engage the sprocket teeth on the pulleys. Be careful not to rotate the pulleys when installing the belt.
  2. Release the timing belt tensioner pulley, allowing the tensioner to take up the belt slack. If the spring does not have enough tension to move the roller against the belt (belt hangs loose), it might be necessary to manually push the roller against the belt and tighten the bolt.

The spring cannot be used to set belt tension; a wrench must be used on the tensioner assembly.
  1. Rotate the crankshaft two complete turns by hand (in the normal direction of rotation) to remove the slack from the belt, then tighten the tensioner adjustment and pivot bolts to specifications. Refer to the necessary illustrations. Make sure the belt is seated properly on the pulleys and that the timing marks are still in alignment when No. 1 cylinder is again at TDC/compression.
  2. Install the crankshaft pulley and belt guide.
  3. Install the timing belt cover.
  4. Install the water pump pulley and fan blades. Install upper radiator hose if necessary. Refill the cooling system.
  5. Position the alternator and drive belts, then adjust and tighten it to specifications.
  6. Start the engine and check the ignition timing. Adjust the timing, if necessary.

SOURCE: Replace thermostat in 2000 ford ranger

the open pipe that you took the hose off of is the thermostat housing, you will need to remove this to reveal the thermostat, make sure you use a new gasket with sealant when reinstalling thermostat housing to prevent leaks and dont over tighten the bolts,run both bolts down as far as you can before final tightning

How do you set the timming on a 2.3 when your putting the new timming belt on

The IGNITION timing on your Ranger is computer-controlled and is not adjustable.


Should the camshaft drive belt/timing belt jump timing by a tooth or two, the engine could still run; but very poorly. To visually check for correct timing of the crankshaft, auxiliary shaft, and the camshaft follow this procedure:
There is an access plug provided in the cam drive belt cover so that the camshaft timing cam be checked without moving the drive belt cover.
  1. Remove the access plug.
  2. Turn the crankshaft until the timing marks on the crankshaft indicate TDC.
  3. Make sure that the timing mark on the camshaft drive sprocket is aligned with the pointer on the inner belt cover.

Never turn the crankshaft of any of the overhead cam engines in the opposite direction of normal rotation. Backward rotation of the crankshaft may cause the timing belt to slip and alter the timing.
REMOVAL & INSTALLATION

  1. Rotate the engine so that No. 1 cylinder is at TDC on the compression stroke. Check that the timing marks are aligned on the camshaft and crankshaft pulleys. An access plug is provided in the cam belt cover so that the camshaft timing can be checked without removal of the cover or any other parts. Set the crankshaft to TDC by aligning the timing mark on the crank pulley with the TDC mark on the belt cover. Look through the access hole in the belt cover to make sure that the timing mark on the cam drive sprocket is lined up with the pointer on the inner belt cover.

Always turn the engine in the normal direction of rotation. Backward rotation may cause the timing belt to jump time, due to the arrangement of the belt tensioner.
  1. Drain cooling system. Remove the upper radiator hose as necessary. Remove the fan blade and water pump pulley bolts.

1999 ford ranger timing marks 2.5

One is on the crank shaft pully (for TDC). It is a line, scribed on the pully, that alligns to a pointer on the plastic timing belt cover. The second is on the cam shaft pully. It can be accessed by removing the rubber inspection plug on the timing belt cover. The third is on the auxillary shaft (oil pump) and is also accessed through an inspection plug on the timing belt cover.

On the cam and oil pump pullies, the diamond aligns to the diamond and the triangle aligns to the triangle (the pullies have both). These should be perfectly aligned when the crankshaft pully line is at 0 deg TDC. If you can't see the marks through the inspection port while the crank is at 0 TDC, you are 180 degrees out - turn the crank one more time.

My timing belt broke on my 1996 Ranger. It's a 2.3 5 spd - Replaced the timing belt, aligned the crankshaft at TDC before teardown and also made tick mark to align it without having to replace timing...

Is it possible that when the belt broke you may have damaged the engine (bent valve). Try advancing or retarding the camshaft sprocket by one tooth and see if that makes a difference.

How to change timing belt on a 1987 ford ranger 2.0L 4C 5speed

You need to get a manual. Try the Haynes manual for your car. Try autozone; generally available for around $20. This is not the type of thing that can be covered here in enough detail to do you any good.
Buy new timing belt. Disconnect negative battery cable. Remove timing belt cover. make sure cylined #1 is set at TDC. making sure all componets are properly alligned and losen tensioner to remove old timing belt. Install new timing belt. Tension belt, ensure all components are alligned properly, replace timing belt covers and reconnect battery.
