With the crank shaft properly locked down, you can now loosen and remove the crank shaft bolt. I used a breaker bar and the 6-point deep socket. Apply force in the counter clockwise direction to break the bolt loose. If you need more leverage, you can slide an iron pipe over the handle of your breaker bar to give more leverage. Since I had the bolt off before, I did not need the extension pipe for this removal.

Once the bolt is loose, remove it and set it aside.

If the accessory pulleys do not come off when you pull on them, you can tap them slightly with a rubber mallet as shown below.

There seemed to be a little bit of rust corrosion holding the A/C pulley onto the crank shaft. I sprayed a little aero-kroil lubricating spray and let is soak in a few mintues.

First we need to relax the tension on the timing belt. Belt tension is adjusted using the adjustment bolt at the rear of the tensioner. The adjustment bolt is locked in place with a locking nut. The nut and bolt are both 17mm. Using a 17mm wrench, loosen the adjustment bolt locking nut as shown below.

Once the belt is off the passenger timing gear, you should be able to remove the tensioner pulley assembly. The pulley assembly is secured using a small 4mm allen head bolt. These can strip easily if they are stuck so be careful when removing the bolt making sure the allen socket is secure and fully seated in the bolt.

You should be able to pull of the tensioner pulley assembly. However, if your tensioner pulley assembly is stuck on the spindle as mine was, you may need some help getting it off. I used this Power Steering Pulley Puller to get a grip on the idler pulley and pull the assemply off the spindle. It's a common tool and can be found at most automotive stores.

I used an M6 (10mm bolt) the same size bolt that is used to secure the water pump to the block (I had spares) as the counterforce for the puller. Insert the bolt part way into the threads as shown and install the puller.

There are 8 bolts to the left of the pulley as depicted in the below picture. The remaining 5 bolts are to the right of the pulley. You will also notice that 5 of the bolts are shorter than the others. These 5 bolts are matched with the holes that are recessed in the water pump housing - there are 5 of them. Finallly, notice the guide pins. There is one on each side of the water pump. Depicted in the picture below is the guide pin on the left side of the water pump. There is another on the right side of the water pump. These are great for locating the water pump properly when installing. However, they can be bent or broken off if the water pump is forced off at an angle.

When all the bolts have been removed, you can pull the water pump off. It will probably be stuck on so you may need to pry it off. The method that works well for me is to gently pry the pump off by inserting a large flat blade screwdriver between the engine block (where the engine block number is stamped) and the water pump housing. Do not pry much, just enough to break the bond and allow you to "walk" the pump off the guide pins. Pull on one side then the other then the other side and so on until the pump comes off.

If you would like to replace a leaking o-ring or seal on the oil pump, this next section should help. However, if not, you can skip to Chapter 13 to resume with the regularly scheduled program of timing belt and water pump. First, we remove the oil pump gear. It is secured with a 17mm nut. You can counterhold the gear using a large flat blade screwdriver or pry bar by inserting the screwdriver in one of the gear holes and catching one of the casting ridges behind the gear as shown below.

You can try to pull off the gear by hand but most likely it will be stuck. Mine was so I used a 2-Jaw puller and it came right off.

Once the gear is off, inspect the coating on the gear. The coating can wear off and expose the soft metal below. If the gear looks like shiny metal, the coating has worn off and the gear should be replaced. If the gear looks like the one pictured below, the coating is still intact and can be put back into service. This particular gear had about 34K miles on it.

Once the gear is off, you can inspect the seals and mating surfaces to look for leaks. You can see here with mine that there is some weeping or light leaking below the oil pump. The brown seal around the pump spindle above the circled area appears clean with no leaks. The lower leak is probably due to a worn out O-ring on the pump housing. It appears the oil pump can be removed without removing the rear plastic cam cover shown in the background. However, since I wanted to clean it all up, I removed the cam cover as illustrated in the following steps.

First, remove the crank timing belt gear from the crank shaft. Sometimes the gear will not slide off because the "key" is angled or wedged in at an angle. If the gear does not slide over the key, you can gently tap the key to align it as shown below.

The oil pump has a seal on the spindle as indicated by the green arrow in the pic below. This seal was in very good shape so I left it alone. However, if you wanted to replace it, when the pump is removed, you can remove the gears and spindle and can easily replace the seal with a new one. That procedure is not covered here.

Also, you can inspect the crank shaft front seal for leaks. It appears from this pic below, my seal may be weeping (slight leak). I decided to leave it alone and monitor it for leaking. If you were going to replace seal. Now would be the time to do it. You can see by the green arrow to the left, there is a canal cut into the engine block that will give you access to pry the old seal out. Once the old seal is out, you can press the new one in. However, that procedure is not covered here. I will replace the seal the next time I'm in there.

To remove the oil pump, remove the three 13mm bolts that secure the pump to the engine block. Each bolt has an umbrella washer and an o-ring. We'll be replacing the o-rings later.

Once you get the bolts out, you will need to pry or pull the pump out. The method that worked well for me was to use a short section of 2X4 and a long pry bar. Put the gear washer and bolt back on the spindle as shown below. Place the 2X4 against the block and use the pry bar to lever against the 2X4 and the washer and bolt to carefully pry the pump out (see below).

The idler pulley can also be replaced at this time. Mine, however, was still in great shape so I did not replace it. If you are going to replace it, you have to remove this circlip as shown in the picture below. Then separate the pulley from the arm and install the new pulley. The idler pulley helps keep the timing belt from flopping and coming in contact with the pulley mounting hardware since the most slack in the timing belt is in the area of the tensioner pulley. I don't belive the idler pulley is replaced regularly.

The bushings are usually a tight fit so you may need to use a "C" clamp to press them in evenly and flush with the mounting bracket. After both bushings are installed the tensioner pulley assembly is ready for installation (later in Chapter 17)

The idler pulley can also be replaced at this time. Mine, however, was still in great shape so I did not replace it. If you are going to replace it, you have to remove this circlip as shown in the picture below. Then separate the pulley from the arm and install the new pulley. The idler pulley helps keep the timing belt from flopping and coming in contact with the pulley mounting hardware since the most slack in the timing belt is in the area of the tensioner pulley. I don't belive the idler pulley is replaced regularly.

The bushings are usually a tight fit so you may need to use a "C" clamp to press them in evenly and flush with the mounting bracket. After both bushings are installed the tensioner pulley assembly is ready for installation (later in Chapter 17)

The next sequence of pictures may seem out of order since the timing belt and tensioner pulley are still on the engine but you can ignore those. I had to use an older set of pictures to capture the rebuild process. To remove the timing belt tensioner, you will need to remove the air pump from the tensioner bracket. Loosen and remove the 13mm pivot bolt on the air pump as shown.

When the bolts are removed, you can use a pry bar to lever off the block and the bracket arm as shown to break the tensioner loose. In case there is any fluid left in the reservoir, you may want to place a rag or towel under the tensioner before breaking it loose.

You can see the gasket was pretty much shot on this tensioner. The tensioner holds fluid (90w Gear Oil) that helps transfer engine heat and provide lubrication to the tensioner washers inside. When the engine warms up, it expands and causes the tension on the timing belt to increase. The purpose of the tensioner is to provide slack in the timing belt to compensate for the extra tension created by the expanding engine.

To rebuild/repair the tensioner, first remove the boot clamp. It is easily removed by placing a screwdriver in the crimped part of the clamp and twisting the screwdriver to open the crimp. Once the crimp is opened, the clamp can be removed.

Hold the tensioner facing downward with your hand over the opening to catch the washer assembly. Carefully remove the washer stack and leave the washer stack in tact. There is no need to disassemble the washers unless they are caked and stuck together. If they need to be cleaned you can remove them. There should be a total of 35 washers. They are concave rather than flat. When they heat up, the washers flatten out.

Here's a close up of the washers. They are grouped in sets of 5. If you have to take them apart you will reassemble in the same order they were taken apart. You will have 7 groups of 5 washers each. The 5 washers in each group will be facing the same direction. Each group of 5 washers will be assembled on the spindle in opposing directions and it should look like the pic below.

Once the spring clip is removed. Remove the metal center section from the old boot and transfer it to the new boot. Install the spring on the new boot with the transferred center piece.

The spring clip should be fully seated in the groove in the boot as shown. Sorry for the fuzzy picture.

Install the boot onto the front of the tensioner housing. Ensure the boot is fully seated over the "lip" of the tensioner housing. You can see the lip on the housing in the picture below.

Install the new boot clamp on the boot at this time but do not crimp the clamp yet. You will need to make sure the orientation of the crimp does not interfere with the timing belt cover.

Fit the timing belt center cover over the tensioner as it would when installed on the block.

Then look behind the cover to see how the crimp is oriented to the cover. Orient the crimp so it is not touching the timing belt cover as shown below.

Fantastic stuff Dwayne. Thank you. This job not scheduled for another year or two on my car but am really looking forward to it with such lucid and thorough instructions.
Have done early parts of this procedure several times for other projects (such as retension, ancillary belt replacement, refurb PS pump) but still found tips and advice I hadn't come across or thought of.
Have read other threads on TB replacement where people have struggled with pulleys/harmonic balancer, and you just calmly use a puller having replaced centre bolts.
