You should take out the fans to get more room to work with, loosen the alternator to remove the belt covers. After this has been done, the crank pulley needs to be removed to get to the crank shaft markings for the timing. The timing marks for the left and right pulleys are dead center on the top, make sure to mark the positions on the pulleys and the notches. The crank pulley has a marking top dead center, and another marking counterclockwise that you have to match up. How to make that match up without moving the other two pulleys, I haven't a clue because no one else has answered this question. If someone else finds out, please add on to this.
with your hands...
its a good idea yes..
in with the timing belt change them at the same time
2 plus the timing belt
there is no such thing as timing belt bearings...... are you posibly thinking of an idler pulley? or cam bearings?
Every 60,000 miles is recommended!
Timing marks on the gears are aligned with marks on the belt. I have seen a Chinese made belt that had the timing marks on the wrong side of the belt so if it just doesn't seem that things are aligning properly, try transferring the marking to the other side of the belt, flip it over, and try again.
It goes by mileage ....100,000 miles is recommended
Yes of course it has a EJ25 Interference engine, if the timing belt brakes the pistons and valves will hit each other.
Timing is done by Engine computer with imfo from cam and crank sensor . It is not adjustable. If you are replacing timing belt, a Gates timing belt comes with detailed instructions of belt and pulley timing marks. New belt has marks on it that correspond with cam shaft pulleys and crank pulley.
Your question is a little vague but I think I understand what you are asking. There are white marks on the edge of the timing belt and white marks on the pulleys. Align those and you are all set.
There should be timing marks on the pulley & you simply align them. Crank at 12/cam at 6.
