Default How to crank engine pulley

I'm going to do an MMO or a Seafoam soak soon and I'm wondering what the best way to crank the engine pulley is. Should I remove the tire and manually crank it? Which direction does it go and which size nut is it? Can one turn it over by using the starter and disabling the PCM Fuse A?

Just use the key and crank the engine.You can pull a fuse or unplug the electrical connector on the ignition module located under the coil packs. Just make sure the the spark plugs are NOT installed when you do this. Or else you'll be looking for a new engine.

There any key way to view the crank pulley without pulling the passenger wheel?

Why do you need to see the crank pulley? Just pull the plugs and crank it with the starter.

Whats your obsession with getting to the crank pulley?

The crank pulley is behind a plastic splash guard inside the wheel well. I suppose you could lift the car, remove the wheel, remove the splash guard, put the wheel back on then crawl under the car or wedge yourself between the wheel and fender to turn the crank by hand.

Or you can turn the key while sitting on the drivers seat.

I dont even get why you want to crank it by hand. You physcially couldnt spin it fast enough by hand to expell the remaining SeaFoam or MMO through the spark plug openings.

Yeah why do you want to crank the motor by hand? Have you ever done that? Its not fun cranking a motor by hand, its not really that easy. 4 cylinder is much easier then a 8 banger.

How are you supposed to know else wise when the notch on the crank pulley is at 90 degrees and the pistons are all at their half way position? This would be BEFORE adding sea foam or MMO. See here Procedure 1 Step 4

From what I've been reading (checked out a Chilton Manual) the only way to see this notch is with the valve cover off? So has anyone actually aligned their pistons 1/2 way before doing an MMO soak?

As you have to have the sparkplugs out to do a piston soak, try this: Remove plugs and stick a straw, not something metal, into any cylinder, say #1 and #2, and either by pushing the car while its in 4th or 5th gear or using a wrench on the crank turn the motor while monitoring the amount of straw in #1 and #2. When it matches they are at the 50% point. If you use 2 real plastic straws of the same length you will be there when the end sticking out is at the same height. This works with #1 and #2 OR #3 and #4. If you have the right wheel and splash shields off ther is a notch in the face of the crank pulley on the outer rim, it is in the edge of the piece the belt runs in, that is the zero degree mark so if you point it at 3:00 o'clock or 9:00 o'clock you are there also

If hand turning the crank by either pushing the car or the big wrench, try and only turn it clockwise. Reverse rotation is not the best thing for the valve train components.

Just saw your post above, you found the mark....

Sounds good, thanks oldnuc, I might try the straw trick and have someone turn the engine over with the starter for me

I just look down the spark plug holes....and stop when they are all close to even...DONE.

Oh and dont use a wrench. Use a ratchet

For other people who may find this thread in a search:
You can see the notch in the crank pulley (very small, about 1mm)
by looking down at it from the front of the engine well with a flashlight. I tried
the straw trick with the started but it turned the engine too fast. Putting the car in 3rd and pushing
it while someone watched the pulley notch for me work perfectly
