Go to an auto parts store or a book store and purchase a CHILTON or HAYNES repair manaul. They will explain this very well and they have pictures to show you the proper marks.

You don't and you can't. Just use the timing mark on the balancer and timing tab/ pointer. Line those 2 up with the # 1 pistion all the way up at the top of the cylinder on the compression stroke. If you are installing a timing chain and gears, just line up the dots on the crank gear and timing gear stright over top of each other. Crank gear will be at 12 Oclock and the cam gear dot will be at 6Oclock. You can't use the fly-wheel because it does not have any marks on it.

The only marks you need to be concerned with are on the rear of the cam gears, there are two large dimples, these are the assembly marks, not the timing marks, line them up and then rotate the camshafts to the top dead center position, there should be two small dots that line up with the single dot inbetween.The reason for the assembly marks is that the one of the cams has a spring loaded gear, you can identify it because it has a two piece gear, before you remove the cam you have to install a short bolt into one of the holes in the gear so that it won't unwind, the reason you need to use the assembly marks is that the service bolt is not accessible with the cams at top dead center so you assemble it with the marks so that you can then remove the bolt and then rotate the cams to the #1 firing position.The only marks you need to be concerned with are on the rear of the cam gears, there are two large dimples, these are the assembly marks, not the timing marks, line them up and then rotate the camshafts to the top dead center position, there should be two small dots that line up with the single dot inbetween.The reason for the assembly marks is that the one of the cams has a spring loaded gear, you can identify it because it has a two piece gear, before you remove the cam you have to install a short bolt into one of the holes in the gear so that it won't unwind, the reason you need to use the assembly marks is that the service bolt is not accessible with the cams at top dead center so you assemble it with the marks so that you can then remove the bolt and then rotate the cams to the #1 firing position.

The rear metal timing belt cover has a notch behind each of the camshafts. Use these notches to put the mark on the camshaft gear starting from passenger side with the #1 on the camshaft gear, then 2,3, & 4 in order. On the crankshaft you must remove the 6 bolt holding the pulley and remove pulley so that you may access the mark on the bottom gear. One you locate that mark that one should be aligned at 6 o'clock position with a recess on the front right underneath that gear. At this point cylinder #1 is at top dead center. If you had removed the timing Gears, Install the gear so the alignment pin on the cam is in the correct, numbered alignment slot on the cam gear, to prevent a 180 degree out cam timing.

5.4 3 valve engine left cam has 2 marks the l shaped arrow goes about 12:00 the right side either has an arrow shped r or the small line on the opposite side of the gear there is dimples on th back of the cam gears but do not use them the crank gear mark is at 6:00 right cam gear mark about 11:00 the 1 colored link on the crank gear the 2 colored links on the cam gear haynes book not very good this came from ford service tech hope this helps

There is no more timing marks for a 98 vortec you have to go off marks on distribitor & use a scanner. You are setting cam timing

User Avatar

on the cam there is a little dot that is machined in the cam gear. make sure that it is at top dead center( remember that the motor sits at a slight angle so it wont look like the very top by looking strait at it. you will have to take the crank pully off to see the mark on the crank gear. the mark is an indentation on the back of the pully. line that up with the little arrow next to the gear. after that is set put the belt on making sure that you don't move the gears. put your pully back on and use a timing light to set the timing at two degrees top side by looking at the marks on the timing belt cover next to the crank pully.

Ford doesn't use timing marks sorry

User Avatar

there are no timing marks for reference. you have to use special tools. I have OTC #6474 you cannot replace the timing belt without at least this one tool. you will also need a cam pulley holding device to retighten the cam bolts. Currently I am doing the job with the proper tools and still having no luck getting the motor to run properly. good luck people

The cam sprockets have marks, triangles on them near one of the teeth. These are lined up with notches in the rear cover for the timing belt. Some crank sprockets have two marks, one to align with the mark on the block, the other to use to match to marks on an OEM timing belt. After market belts don't usually have this mark.

User Avatar

on the crank pully there is a mark that must line up with a mark on the egine block, the cam shaft pullys there are holes that will line up with holes in the engine block, use pins to make sure they line up, once all marks are lined up then just put on the chain and set the tensioner

User Avatar

There are none. The cam needs to be set with a plate and use pins to set the crank and fuel pump pulley.

I don't know how much you know about the subject so I will start at the beginning. First you have to get to it, you can pull the motor or leave it in the vehicle. Its a little harder with it in depending on the space you have in engine compartment. If your leaving the motor in, which I imagine you are, your going to have to take the front end of the vehicle apart. Remove the grill, bumper if need be, radiator, fan, water pump, harmonic balancer, you will need to buy a puller and a installer for the harmonic balancer. You can get a puller kit from harbor frieght tools for $10. You can buy the installer from summit raceing (web site) for arround $30 or you can buy one that will do both the install and removal from summit for $70. Once you have removed your harmonic balancer you can remove your timing cover to expose your timing chain. Turn the motor using a socket wrench until the timing marks on the crank gear and cam gear line up. The marks are usually just white dots, you want the crank mark to be up towards the cam and the cam mark towards the crank, the marks will be up and down from each other. Once you have the marks lined up remove the bolts holding the timing chain to the cam and crank. Remove the timing chain as a whole unit with the cam and crank gear still on it. If the crank gear doesnt want to come loose use your puller on it. when you get it off just put your new gear on and line up the timing marks then put it back on as one unit. If you cant get the crank gear on all the way by hand buy a crank install tool (summit) they run about $24. While you have the thing apart it would be a good Idea to put a new timing chain on. Depending on your vehicle this would also be a good time to change your cam if need be. Its not that hard to do it just takes a while, take your time and don't force anything.

On my 2000 Metro with a 1.3L the mark and slot marked with the "E" are used.

Timing marks determine if the car is set on TDC(Top Dead Center). Just to make sure it is in time use a Timing Light. The timing marks are located on the sprocket under the valve cover and on the crankshaft. Timing marks determine if the car is set on TDC(Top Dead Center).

the correct alighnment is at TDC marked on crankshaft pulley = groove in tail end of both cam,s vertical with the pulley dowels uppermost on both cam,s = no 1 lead on distributer firing. cam pulleys are universal inlet cam should use the I and respectivly the exaust will use EX to identify location of dowel locating slot used

User Avatar

On the cam the mark that has a T next to it. There should be two marks and only one w/ a T next to it. That meas TDC.

User Avatar

the timing marks are on the rear of the engine @ the top of the transmission bell housing,use the mark on the flywheel & pointer on the bell housing to line up the timing marks.

Wich marks can u use to set it on time if the marks are erased

User Avatar

there is a mark on the bottom puley line this up use the longer bolts from cam belt cover to lock up pump and camshaft

The 2000 Ford 4.2 engine does not have any timing marks on the crankshaft. Instead, you have to use a timing kit to install a new belt.

User Avatar

if you mean the ingintion timing marks, they are on the crankshaft pully. Use a rag and some cleaner to see them clearly.

User Avatar

It is impossible to get the cam 180 out if you use the right tool. The grooves are offset in the cams, so that it will be impossible to install the tool if the cam is 180 out, because the groove will be below the deck surface if it is not in the correct position.

Chevrolet Celebrities use timing chains, not timing belts. The two sprockets are each marked, simply align the marks with the centers of the cam and crankshaft. See a factory service manual or a Chilton or Haynes manual for a picture/drawing.

When you say 'Timing Marks', there are several places on this engine that has various marks in regards to the Harmonic Balance, Camshaft sprockets, crankshaft, and timing cover. If you are checking the timing, you will use the marks on the timing cover. If you are setting or replacing the timing belt, you will want to use the camshaft sprockets in relation to the crankshaft/harmonic Balance. On this year, the crankshaft key notch should be 12'oclock and the sprockets should have the timing marks 'E' for exhaust and 'I' for intake aligned facing with the 'E' at 3'oclock and the 'I' at 9'oclock. Hope this helps. AJ
