The marks on the cam sprockets point up and they should align with the marks on the rear timing belt cover (behind the sprockets)

I have a 1994 Toyota corolla changed the timing belt tensioner. trying to set timing, all marks line up except camshaft dots, can't get them to face each other without throwing off all the other marks


If you removed the tensioner and didn't lock the cams and crank down then you have to re-time the engine. It sounds like you let the exhaust and intake cams move.

Remove the spark plugs, put a ratchet on the crank pulley, slowly rotate engine until the cams line up. Once the cams are lined up remove, the timing belt and bring the crank around to the timing mark. put belt back on and let the tensioner go. put plugs back in...see if it'll start.

There's a dot on the cam and a mark on the head turn the cam over with a ratchet and socket it should pop into place be sure to line up both cams one on each head and the bottom on the crank there's a mark on the pulley for the belt you should buy the timing belt kit it comes with new idler pulleys and you should also change the water pump while your in there it runs off the timing belt the new timing belt I put on had dots on it to help line up the timing marks

How to put back the timing belt


line up the lines on the belt with the dots on the sprockets and you cant miss.there is also two small dimples on the cover behind the cam sprockets that you can use to line up dots on face of cam sprockets with.the belt should have marks to indicate which side faces outward toward front of vehicle.turn crankshaft until dot on its sprocket is in roughly the five oclock position.align solid line on belt with this dot(area of belt with words on it will need to be between cam sprockets.i find it helpful to wedge a piece of cardboard between belt and lip on oil pump to hold belt in position on crank sprocket.next align the next solid line with the tooth on the DRIVERS cam sprocket that has the dot on it.....this shoul be roughly two oclock position.lastly align the hashed line on belt withdot on passenger side cam sprocket....this will be in roughly the 11 oclock position.loop remainder of belt behind tensioner pulleyand set tension.as long as themarks on the belt line up with marks on sprockets properly you cant miss.

I have found the crankshaft marks but I cannot find marks to align the to over head cams on my car, the dohc are run from 1 wheel. I am trying to re-align the timing belt as i think they have gone off.


if it's a dual overhead cam then each head has two cams and two pully's, a single overhead cam engine has one cam and one pulley on each head. if the belt has more than 60,000 miles on it you should replace it. you need to find out if the engine is an interference engine or not to determine the level of damage caused if the belt has jumped or slipped. your overhead cam timing marks are usually on the cam faces and the backing plate behind the cam or sometimes there's two marks on the cam that you align with the surface of the head behind them. the first thing you need is a diagram of the belt routing and mark positions because timing marks are very important especially on an interference engine. starting or cranking an interference engine with the timing marks misaligned can bend all your valves or even punch holes in your pistons! so proper alignment is crucial, good luck.

How do you set the timing when installing new timing belts


Depending on make and size of engine u need to get the #1 piston at tdc top dead center u do this by taking the spark plug out of the #1 cylinder put yure finger in sparkplug hole and turn cranshaft till u feal yure finger being pushed out by compression now take a straw and put it in the spark plug hole u will need a breaker bar on larger engines to turn the crank with the bolt on the pully small 4 cyl u can turn it by hand once u feal the straw being pushed out of the whole turn the crankshaft back and forth to get the straw exactly where its all the way up just before it goes back down yure at tdc now on the gears there is a dot or a mark on the front side line them up using a straight edge line them up so both marks are on the inside facing one another pull both gears out leave the bigger of the two on the shaft place the belt on the smaller of of the cam shaft now u want to put the belt on the bottom side of larger gear and try and get the teeth so the top and bottom gear marks line up again when u push cam gear on splean of cam shaft if they apear to b lined up a little at a time push crankshaft gear n a bit then cam shaft gear switching between the two till they are all the way seated and there u go

Need to know where the timing marks are on a 1995 Monte Carlo


3.4l double overhead cam ? i'm told the 95 is the only 1 with non-interference valves when the timimg belts go out . once you have the crank on #1 top dead center and your positive, there should be a notch in the top of the flywheel . and the cams on the firewall side will have flat spots facing down while the front side will have both cam flatspots facing up .anyways that's a rough idea what you need to get it to do.

How to set timming belt,cant find mark for crankshaft 3.0L


Timing belt removed, static timing was not set before removing timing belt.

[Set Static Timing:
No.1 piston is brought up to TDC before removing timing belt.

Cam gear has a punchmark on face of gear, and this mark aligns with one single tooth. There is a matching punchmark on the Timing Belt Rear Upper Cover.

Facing the cam gear, the mark is to the upper right. There is an 'egg shape' of the timing belt upper rear cover, in this spot. This punchmark is in that 'egg shape', and is close to a bolt hole. The cam gear mark lines up with the Timing Belt Rear Upper Cover, mark.

The crankshaft gear has a punchmark on the face. It lines up with one single tooth. There is a corresponding punchmark on the lower right side. An alignment mark)

Should be a round punchmark on the face of the crankshaft gear. It lines up with a single tooth. Wipe the gear clean, use a little carb cleaner. (NO flames, or sparks nearby, well ventilated area)

Barring you cannot find the crankshaft mark, find the camshaft alignment marks, make sure they are aligned with the alignment, (Punchmark), on the Timing Upper Rear Cover.

Count the teeth in the timing belt. There should be 133 teeth on the belt.

There is 43 teeth in-between the timing mark of the camshaft, and the timing mark on the crankshaft.

(43 teeth in-between the Right Side Camshaft mark to crankshaft mark, 43 teeth in-between the Left Side Camshaft mark to crankshaft mark)

There should be 40 teeth in-between the two cam gears.

Please help me time volvo 960 engine


get the no.1 piston up on TDC on compression stroke, find where the no.1 lead attaches to the distributor cap, mark the side of the distributor if it is not already marked.
When you are ready to put the distributor into the hole of the inlet manifold put the rotor button on the top of the shaft and make sure it seats right down, you will notice that it turns when putting it in, the centre of the rotor button has a line in the middle of it which should line up with the mark on the body of the distributor, make sure the distributor body is facing in the direction it was facing before you removed it, this should get the motor to run so long as the rockers have been adjusted properly, use a timing light to time the motor

Timing belt settings


the tension setting for the belt?

or the timing marks? the timing marks differ. best set cyl. no 1 to tdc.. take out no. 1 spark plug and put sumthin long and thin down the hole.. like a long quarter drive extension.. and check to see that cyl 1 is at tdc.. then set your cam to the OT marks marked on the cam pulley and rocker cover... then you have to set the distributor also.. slacken the 13mm bolt for the dizzy clamp... you will find a line on the lip of the dizzy body.. this needs to align with the middle of rotor arm tip... (sumtimes a mark on the roror arm tip)... tension belt and your timing is set.. set your timing incorrectly and the car will run rough and not rev past 5k...
