S15 timing cover

Im having a hard time removing the nut (15/16) to pull the pully off. Is it possible these are reverse threads? Also do I have to take the alternator and all the brackets off to remove thi timing cover? Thanks, Mark

Apparently if you put a socket on it and rest the bar on the chassis, you can flick the key to lossen the bolt, but make sure you disconect the coil first so the engine doesnt fire up, im useing that method tomorrow if i have trouble getting mine off, good luck.

If you are replacing the crank seal you do not have to remove cover,and yes you have to remove alt bracket to remove cover. not reverse thread on crank pulley take a 15/16 boxed wrench and hammer and keep banging.i just did mine this weekend

Remove ford 4000 steering wheel

Screw the nut off until it is just slightly above the shaft level but still has several threads engaged. Then pull the wheel up as hard as possible towards you. At the same time have someone hit the nut sharply with a brass hammer or similar. The shock should free the wheel on the spline,then remove nut completely and take wheel off! Brass or similar is best to use so the nut does not get damaged...

99 sable crank pully nut

It's a bolt, and if left hand threads, it will be the first time I have heard of such. No pin would be through the threads. Try the breaker bar or impact gun the other way. If engine tries to turn, pull the starter and wedge a block of wood against the ring gear teeth on the flywheel.
Don't know about sables, but thought all crank bolts were regular threads.

I need to see how to replace my water pump on my 2001 dodge durango 5.9l v-8 engine

You need a large adj or a whench that fits tight on the clutch fan nut remember the nut is reverse threaded, I'm sure they make a proper half moon wrench with 2 pins to fit into the holes in the pully, however you can put 2 bolts in the holes and using a long bar to keep the pully from turning. you have to hit the wrench pretty hard with a hammer to get the clutch loose so make sure your bar doesn't bounce or it can damage your pully. once the clutch is off remove your belt and the pully and your at the WP. you don't have to hit the clutch as hard when you put it back as engine torque will tighten it more . I hope this helps.

Oil leaking on front of motor? it looks like its comming from lower pully. i bought seals i just need to know how to replace.


You need to remove the fan-belts etc. The fan and the radiator.

Then you need to remove the nut/nuts in the centre of the bottom pulley and remove the pulley.

Then you need to remove all the timing cover bolts and remove the timing cover, once this is removed pull the seal out and then replace it.

You then just do the exact reversal of the removal procedure to refit it.

There is no timing or anything like that that you have to look out for.

Let ma know if you need more information.

Trying to find procedures for a 2001 bmw z3 3.0 water pump replacement

to start you will need a 32 mm wrench and long narrow flathead to remove the fan blade,looking at the motor is releases the the right,spin off the blade and remove along with fan shroud for accesabilty,loosten the 4 10mm nuts on the water pump pully before removing the belt as bekt will hold tension but dont fully remove the bolts just release a couple of turnsuse a 16mm socket or a 8mm hex key to remove the alternator w/p belt,no need to remove fully,there will be either a hex head for a socket on the belt tensioner and if not pop off the plastic cover on the front of the pully to reveal a hex key bolt, once the belt is off remove the 4 w/p pully bolts, if the pully doesnt come right off lubricate with penetrating oil and tap lightly with a hammer while spinning it slowly and it will release,now that the pully is removed you can now see 4 10mm nuts hold on the w/p.remove the nuts and spray aroung the pump with wd40,you can try to pull and wiggle on the pump, if it doesnt come out you must obtain 2 bolts that will fit to the sides of the pump, you will see two thread holes that are empty,when you thread a bolt through with even tension on l and r sides the w/p will begin to pull away from the block. Once the pump is out lubricate the new pumps o ring with coolant to help slide it in, push in the new pump and re assemble in reverse,to fill the cooling system open the phillips screw on the overflow expansion tank,fill system with a 50=50 mixture of coolant until coolant comes through the bleeder screw with no bullbles,close the blleder screw and run the car at idle with the windsheild defroster on and heat at full. monitor the coolant level until it has sufficient flow and close cap,you can have a friend rev the engine to about 2000 rpm for this, road test the car and allow to cool, re check for leaks and fluid level when cold again to ensure repairs are correct

How do i change a timing belt on a 1990 toyota celica

This is a 5 on the 1-10 scale. You will have to remove: The serpentine belt, and all pullies on that side of the engine. Then remove the retaining nuts all the way around the timing belt cover. Once you have it off, you will have to remove tension on the belt using the tensioners (2) inside the belts travel. I do not know if you have a single cam or twin, but the proceedure is basically the same. Once the tension is off, you can replace the belt, and reverse the order of steps. I recommend a good sealant be applied to the cover where it meets the block, and a good thread-lock (locktite.) Be sure to align the belt the same as the one taken out and NEVER MOVE THE CAMS!!! IF you do you have to retime the engine from the gear points.

Need to change timming belt 1997 geo tracker

TIMING BELT CHANGE You should have some mechanical skills before attempting any engine maintenance! These are basic instructions, and you must knoe what you removed, when, and what order so you can reinstall them in order. First, you have to remove everything in the way! You need to remove the Fan, clutch, and shroud, pump pully & drive belts. Next, you need to remove the Crank Pully:

1. Crank Pully Bolt 2. Crank Pully 3. Center Bolt 4. 5mm Hex drive (used to remove pully bolts) Once the fan stuff, and pully(s) are removed, then you need to remove the Timing Belt cover:

Once the cover is removed, you will need to loosen the adjusting nut and pully bolt on the Belt Tensioner:
A. Adjust Nut B. Pully Bolt C. TENSIONER PULLY Once the the Adjust Nut, and Pully bolt are loose, move the pully as far towards the water pump as possible.
Then, you can slip the timing belt from the sprockets. Check the tensioner for roughness and excess play! DO NOT MOVE THE CAM OR CRANK SPROCKETS! IF you do, then you will have to line up the Crank and Cam for piston number one at Top Dead Center before placing the new timing belt on! Note the timing marks on the crank and camshaft sprockets. IF YOU MUST! Allign the Cam and Crank at piston#1, Top Dead Center before removing the belt. Each sprocket has a small hole, with a line through it, and there is a small groove or "V" it alligns with on the engine. Now, once the timing belt is off, look at your new timing belt. Older belts use the Squared off teeth, while new ones have the rounded teeth. Make sure you have the correct belt for your sprockets! Never reinstall a belt that is in questionable condition. BELT WEAR CONDITIONS
If there are Arrows on the belt, they must be pointing to the RIGHT when you put the new belt on the sprockets. If there isn't one, then paint one on, and place the belt back on the sprockets. The arrow will indicate to a mechanic, this is the way the belt must be put back on (if they replace any cam or crank oil seals). Slip the new belt onto the Crank sprocket. While maintaining tension on the side of the belt opposite the tensioner, slip the belt onto the Camshaft sprocket. Releace the Tensioner adjusting nut to allow spring tension against the belt. Temporarily reinstall the crank pully, taking care to align the notch in the pully with the raised area on the sprocket. Rotate the crank clockwise two complete revolutions. Recheck the alignment of the of the valve timing marks. If they do not align properly, loosen the tensioner, slip the belt off the crank pully, align the timing marks, reinstall the belt, and check alignment again. Tighten the tensioner nut, then the bolt. Reinstall all parts removed, in the opposite order, of course. Start the engine and allow to reach normal operating temp, then road test. THEORETICALLY, you should simply be able to replace the belt with the new one, and go, as long as you did not move any of the sprockets when removing or installing the belt. Most people do it this way, and do not test for alignment before replacing everything. When the belt wears, timing will be off, very little, and this is why you check alignment. The belt may have slipped a tooth, making the timing off. This is why the Cam and Crank sprockets must both align properly. An experienced person will do just that: Replace the belt, and go. It really isn't all that hard. It helps to have a second person around with some experience also.
