remove #1 spark plug.

1. Rotate the engine so that No. 1 cylinder is at Top Dead Center (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 be sure that the timing mark on the cam drive sprocket is aligned with the pointer on the inner belt cover.
   NOTE

   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.
   

2. Drain cooling system. Remove the upper radiator hose as necessary. Remove the fan blade and water pump pulley bolts.
   CAUTION

   When draining the coolant, keep in mind that cats and dogs are attracted by ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old.
   

3. Loosen the alternator retaining bolts and remove the drive belt from the pulleys. Remove the water pump pulley.
   

4. Remove the power steering pump and set it aside.
   

5. Remove the 4 timing belt outer cover retaining bolts and remove the cover. Remove the crankshaft pulley and belt guide.
   

6. Loosen the belt tensioner pulley assembly, then position a Camshaft Belt Adjuster tool T74P-6254-A, or equivalent, on the tension spring roll pin and retract the belt tensioner away from the timing belt. Tighten the adjustment bolt to lock the tensioner in the retracted position.
   

7. If the belt is to be reused, mark the direction of rotation on the belt for installation reference.
   

8. Remove the timing belt.
   

   Camshaft, auxiliary shaft and crankshaft timing belt sprocket alignment mark locations-Mazda B-Series Pick-Ups 2.5L (VIN C) engines
   

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.
   NOTE

   The spring cannot be used to set belt tension; a wrench must be used on the tensioner assembly.
   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.
   

3. Rotate the crankshaft 2 complete turns by hand (in the normal direction of rotation) to remove slack from the belt. Tighten the tensioner adjustment to 26-33 ft. lbs. (35-45 Nm) and pivot bolts to 30-40 ft. lbs. (40-55 Nm). Be 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.
   

4. Install the crankshaft pulley and belt guide.
   

5. Install the timing belt cover.
   

6. Install the water pump pulley and fan blades. Install the upper radiator hose if necessary. Refill the cooling system.
   

7. Install the accessory drive belts.
   

8. Start the engine and check the ignition timing. Adjust the timing, if necessary.

The timing belt can be inspected by removing the upper (front outer) timing cover.

1. Disconnect the negative battery cable.
2. Remove the accessory drive belts.
3. Remove the timing belt covers.
4. Identify the timing belt running direction to avoid reversal during installation.
5. Loosen timing belt tensioner bolt and remove timing belt.
6. Remove the crankshaft sprocket flange.

To install:

1. Rotate the crankshaft sprocket until timing mark on crankshaft sprocket is lined up with the oil pump timing mark at 1 o'clock position.
2. Rotate the (inner) camshaft sprocket until mark on (inner) camshaft sprocket is lined up with the timing mark on alternator bracket.
3. Rotate the (outer) camshaft sprocket (radiator side) until mark on the sprocket is lined up with the timing mark on the timing belt inner cover. Refer to timing belt illustration.
4. Install the timing belt on the crankshaft sprocket while maintaining pressure on the tensioner side.
5. Position the timing belt over the camshaft sprocket (radiator side). Next, position the belt under the water pump pulley, then over the (inner) sprocket and finally over the tensioner.
6. Apply rotating force in the opposite direction to the camshaft sprocket (radiator side) to create tension on the timing belt tension side.
7. Rotate the crankshaft in a clockwise direction and recheck engine timing marks.
8. Install the crankshaft sprocket flange.
9. Loosen the tensioner bolt and allow tensioner spring to tension the belt.
10. Again rotate the crankshaft in a clockwise direction (2) full turns. Recheck the engine timing. Tighten the tensioner bolt to 23 ft. lbs. (31 Nm).
11. Install the timing covers.
12. Install the accessory drive belts.
13. Connect battery negative cable.

The water pump is driven by the timing belt, so it is best to change that too. If I remember right the V8 has 4 cam shafts and uses a hydraulic tensioner. Since you have to precisely line up all the timing marks on the cams and the crankshaft, This job is best left to a person that has a good knowledge of this engine or a better than average skill level. failure to install the timing belt properly may result in extensive engine damage.

The procedure for timing belt removal is as follows: remove the accessory belt(s). turn the engine by hand so that cylinder #1 is at top dead center. You should have timing marks on the crankshaft ulley and the timing cover. remove the pulley. then remove the timing covers. You will have to support the engine from underneath as you need to remove the engine mount to take the belt off. INSURE that all the timing marks line up and rotate the engine as needed to achieve this. Take the belt off and then you can remove/replace the water pump. Install the timing belt and isure that all the marks line up after you reset the tensioner. Rotate the engine clockwise 2 full turns and check all the timing marks. If any are off then re install the belt again. After that put the timing cover back on and install the crankshaft pulley. then install the belt and fill the radiator. run the engine with the radiator cap off until tthe thermostat opens and add water to the right level.

The following steps need to be taken to remove the pump.

1. Remove the ribbed belt. Compress the tensioner and remove the belt. Remove the ribbed belt tensioner.

2. Remove the upper timing belt cover.

3. Align your timing belt marks. The following pictures are for the cam timing mark, the flywheel timing mark for an automatic, flywheel timing for a manual and the marks on the harmonic balancer.

4. loosen the timing belt. There is a 13mm head nut that keeps the tensioner in place. Loosen this nut and turn the tensioner clockwise to get come slack in the belt. You are going to need a tool to get tension back on the belt. I use the tool pictured (picture of how to tension the belt) but know of people using snap ring pliers to rotate the tensioner.

5. Slip the timing belt off of the cam drive sprocket and off of the water pump.

6. Remove the water pump retaining bolts pictured and remove the water pump. The pump can often be stuck in place. A screwdriver carefully used can help in getting the pump

7. Moisten the o-ring with coolant before installing the new pump. Install the new pump.

8. Install the belt and tension as shown in the picture attached above. Turn the engine over by hand through a full revolution of the cam gear. Re-check the timing marks. The marks will often be off, don't be discouraged by this, it happens to everyone. If the marks are off loosen the belt and slip it the amount of teeth needed to align the marks.

9. Install the items taken off during the removal of the pump, fill the system with coolant and start the engine. The system will pretty much bleed itself out as it reaches operating temperature.

If you need to remove the crankshaft pulley nut with rope method, you can determine the TDC of a cylinder by tracing the sparkplug cable back to the distributor cap and looking at the rotor position. It should be in the firing position
Here's some info in found if you want to remove the water pump as well, or you can ignore that.
From my research the idler bearing probably should be changed. If it goes the belt will slip and destroy the engine.

The real work is getting to the belt, not replacing it
.
When you get one set of marks (camshaft or crankshaft) to line up then look at the other set. It is right since the engine is working. Probably the crankshaft gear will have 2 teeth with lines cut in them, one line in the valley or a chip on a tooth. You can mark the unit also. Remember do not rotate the camshaft/crankshaft with the belt off. Keep them aligned with the marks.

Remove the serpentine belt using a 3/8" drive breaker bar or ratchet to release the tensioner.



Remove front timing belt cover
Remove splash guard under engine
Remove vibration damper guard
Remove ignition coil cover from top of engine

Note: the belt can be replaced without removal of the splash guard. The vibration damper guard can be removed from the top. It is held on by two 10mm bolts. One is toward the driver's side (about 4 o'clock if looking at damper) and the other one is toward the bottom (about 6 o'clock). You'll have to feel around for them, but you can get them with a ratcheting wrench. If you cannot feel them, they are visible from below with the splash pan removed



Turn the engine clockwise until the timing marks align as shown on the upper cover.
Remove upper timing cover


Removing timing belt:
Remove tensioner upper mounting bolt.
Undo lower mounting bolt.
Twist tensioner to free plunger.
Remove bolt.
Remove tensioner.

Note: If the timing belt hasn't been replaced, it is a good idea to replace it at this time. If the tensioner is leaking fluid, replacement is necessary. Even if you are not replacing it, it must be removed to compress the plunger for installation of the belt when finished. Be sure to make note of which side of the tensioner unit faces out.

Do NOT rotate the camshafts or crankshaft with timing belt removed. Engine damage will occur!

Spin the tensioner and idler pulleys. Replace if excessive bearing noise or grinding is heard.
Remove belt.




Install timing belt:
Place belt around crankshaft pulley and right-hand idler.
Place belt over camshaft pulleys.
Position belt around water pump and press over tensioner pulley.

If reusing the old tensioner, you must compress the plunger again. Make sure the hole in the plunger lines up with the hole in the body of the tensioner and place in a vice with the side that faces out pointing up. SLOWLY compress the plunger using the vice, stopping frequently to allow the hydraulic fluid to move. Once the hole in the plunger is even with the hole in the body, insert a nail, pick or similar through to hold the plunger in place. Make sure it is long enough to be grabbed and removed once tensioner is installed.

Install the tensioner, torquing mounting bolts to 25 Nm (18 ft lb)
Remove locking pin/nail/pick
Install upper timing cover and make sure timing marks still line up. Wait 5 minutes for tensioner to fully extend.
Rotate the engine by hand clockwise two full revolutions, making sure marks line up each time.
Reinstall covers and serpentine belt as shown:



Also, there is a mark on the crankshaft gear that should line up with a mark on the engine when the timing marks line up. I do not have a picture of it, but you should see what 'm talking about..

Actually replacing the water pump is quite simple. First, drain the coolant:


When the belt is off, remove the 7 bolts that hold the pump to the engine. Clean the gasket mating surface and install the new pump. Then continue with installing the timing belt.

To install:

1. Rotate the crankshaft sprocket until timing mark on crankshaft sprocket is lined up with the oil pump timing mark at 1 o'clock position.
2. Rotate the (inner) camshaft sprocket until mark on (inner) camshaft sprocket is lined up with the timing mark on alternator bracket.
3. Rotate the (outer) camshaft sprocket (radiator side) until mark on the sprocket is lined up with the timing mark on the timing belt inner cover. Refer to timing belt illustration.
4. Install the timing belt on the crankshaft sprocket while maintaining pressure on the tensioner side.
5. Position the timing belt over the camshaft sprocket (radiator side). Next, position the belt under the water pump pulley, then over the (inner) sprocket and finally over the tensioner.
6. Apply rotating force in the opposite direction to the camshaft sprocket (radiator side) to create tension on the timing belt tension side.
7. Rotate the crankshaft in a clockwise direction and recheck engine timing marks.
8. Install the crankshaft sprocket flange.
9. Loosen the tensioner bolt and allow tensioner spring to tension the belt.
10. Again rotate the crankshaft in a clockwise direction (2) full turns. Recheck the engine timing. Tighten the tensioner bolt to 23 ft. lbs. (31 Nm).
11. Install the timing covers.
12. Install the accessory drive belts.
13. Connect battery negative cable.

Hope this helps.
