Be aware the oil pump pulley drives a balance shaft, and due to the gear reduction in the oil pump the timing mark is only correct once every 720 degrees. Meaning if the oil pump sprocket has spun with the belt off the vehicle and you realign it to the timing mark you have a one in two chance of it being correct. To verify you have the correct position, there is a 14mm bolt in the left hand side of the block (right on the balance shaft ‘tunnel’. When this bolt is removed, you will be able to stick a screwdriver or othr metal object 2.5 inches into the block when it is in the correct position; the shaft also will not turn more than 15 degrees in either direction. When you are out of phase, you will only be able to go in about one inch.

Knowing When To Change A Timing Belt

Changing a timing belt on your vehicle can be a very time consuming. This is due to the fact that there are a lot of components under your hood that must be removed before you can even get to your vehicle’s timing belt. This is why it is best to change a timing belt at the same time that you are planning on doing other repairs and maintenance practices to your vehicle such as putting on a replacement water pump or changing belts like the serpentine, air conditioner or water pump belt.
Timing belts tend to begin breaking down at around 60,000 miles. You will notice the power to your vehicle begin to slow down, the fuel efficiency of your vehicle can be affected as well as your vehicle showing signs of working harder.
How To Change A Timing Belt or Timing Chain
Different vehicles have different patterns for changing a timing belt or timing chain. The best thing to do when you want to change the timing belt is to look over your owner’s manual that is specific for your make and model vehicle. You can also purchase an automobile repair manual that is designed specifically for the needs of your automobile at any automotive repair shop in your local area.
The basics to changing a timing belt on the vehicle however are pretty much uniform. The steps to do this are as follows:
Step 1. Before you can replace the timing belt on any vehicle it is a good idea to let the vehicle sit overnight so that the engine is completely cool and there is a reduced chance of experiencing serious burns from the engine.
Step 2. As it is with most vehicle repairs you must first disconnect any power supply to the vehicle. This means that the battery cables must be removed from the battery terminal and tied back so that there is no risk of them touching the posts or other parts of the vehicle while working.
Step 3. Place blocks in front and behind the wheels of your vehicle so that there is not chance of the vehicle rolling and accidentally causing injuries to you or others who may be around.
You will now need to remove any obstructions that may be in the way of getting to your timing belt. This includes:
Step 4. Make sure that the air intake assembly to your vehicle is completely removed.
Step 5. Locate the pulley that powers the supply to your water pump if this is in the way on your vehicle. You will need to loosen the bolt holding this pulley in place.
Step 6. For some vehicles it may be necessary to do the same for other equipment such as the power steering pump. This will require you to loosen the bolt and remove the belt that is around the pulley. You can then unbolt the power steering pump and move it out of your way.
Step 7. Line up the mark on your crankshaft pulley to the O that is on the timing scale with a large wrench. You can find the timing scale molded on your vehicle engine block.
Step 8. Using the right sized socket you will have to removed the bolts that are holding the timing belt cover on. When you have the bolts removed you can then pull off the timing belt cover.
Step 9. Inspect the timing belt tensioned bearings for any looseness or noise. If these problems exist you will need to replace the timing belt tensioned bearings as well.
Step 10. Locate your camshaft and check to makes sure there are no leaks in the crankshaft or camshaft seals. If you do notice leaking this could be an early sign that there will be premature failure for your new timing belt. It is best to replace these seals now instead of waiting for bigger problems and the chance of having to do all of this work again.
Step 11. For most vehicle makes and models you should now be able to locate the timing belt. Make sure that all timing marks on your belt are properly lined up. Loosen the timing belt tensioned and you will then be able to remove the timing belt very easily. Make sure that the camshaft and crankshaft for your vehicle’s engine are secured and that they do not move while your timing belt is off of your vehicle.
Step 12. Place your new timing belt on the same way that you removed it. Make any tension adjustments to the timing belt as necessary. Inspect the new belt to make sure that it is fitting over the teeth for the timing sprockets correctly. Makes sure that you do not over tighten the belt.
Step 13. When replacing the timing belt cover install a new gasket to seal the cover correctly. Do not use an old gasket as this will not seal properly.
Step 14. If you had to remove any pumps at the beginning of this project you will now have to hook them back up again. This includes the water pump, power steering pump as well as any other accessories that may have gotten in the way at the beginning of this project.
Step 15. Visually inspect all timing marks to make sure that they are still aligned correctly.
Step 16. Reinstall your vehicle’s air intake assembly that was removed in the beginning.
Step 17. Reconnect your vehicle’s battery. Make sure that there is no corrosion around the posts or the battery cables while you are at this step.
Step 18. Turn on your vehicle and look for any problem areas such as leaks that there may be prior to driving your vehicle. Do not hesitate or postpone any repairs that may be needed.
