Cams are set with the #1 piston NOT AT TDC. You need the cam tool to set this. DO NOT EVEN TRY TO DO THIS WITHOUT IT. ther e are NO reference points which allow you to do this any other way. I am a 35 year master tech and trust me on this. It is not like other engines.

03 dodge stratus 8th digit x changed timing belt old belt still on the car marks were wright now have no comp. u tell me i hope

If the engine is an interference type then moving the crank or camshaft with the belt off is likely to bend some valves if any but the most delicate touch is used.

Positioning the timing marks or even making some new temporary marks before removing the old belt and then without moving anything fitting the new belt - if that is what you did and the engine had compression before it will have compression now.

Clearly you did something different or perhaps you failed to tension the belt correctly and it jumped some teeth when you began trying to start the engine.

Sometimes manufacturers provide a number of marks for different purposes and perhaps you used the wrong marks, maybe the right marks are absent.
I suggest you verify the marks you used by positioning the crank and camshaft(s) the old fashioned way - setting number one piston to TDC and number one valves to the compression (or overlap) position would usually find the marks somewhere near alignment if they are good.

It is possible Dodge did something unconventional so model-related information would be helpful, often that is provided with the new belt. Check and double check and proceed cautiously is the rule regarding timing belts.

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.

How can I time a distributor without a timing light or wheel on a skid steer?

is this a points distributor
place the timing mark at the desired position before tdc compression stroke ( normally around 10 degrees )
se the points to correct gap
turn on the ignition and move the distributor body against direction of rotation until the points just open ( noise or spark across points
tighten the distributor at this position
replace cap and it will start
alight when used will show the timing to be almost at that setting
if pointless distributor
set the timing mark as described and the set the apex of the exciter at the mark on the small pickup in the distributor
That again will be the timing mark setting
if it is an efi engine
the ecm unit will determine the timing of the engine from the crank position sensor

I have 1991 subaru lagacy one day it just stop running,found the timming belt had jumped replace the belt it will try to start but wont,rechecked marks on belt all line up.i have spark and 43 psi fuel...

I hate to mention it but,a lot of cars(imports) when they jump time,they also bend valves.They call these interference engines.The piston hits the valves,when they are out of time.the car will not run unless the head is pulled and reworked.If you call NAPA auto parts,and ask for the price of a timing belt ,and then ask,is this a interference engine? and they will tell you for sure if it is in most cases.

Timing belt alignment

A factory service manual would help, but I'm assuming that if you had one, you probably wouldn't be on this site.

To set the timing, you need to first perform the obvious: remove the accessory drive belts, cam pulley covers, and engine fan and hub. Next you'll need to rotate the engine by hand until the timing marks on the camshaft sprockets and crankshaft are aligned with their corresponding stationary marks. The 0 degree mark on the lower timing belt cover is the timing mark for the crankshaft pulley. There is a mark (small, vertical formed indentation) for the left camshaft pulley on the backing plate behind the pulley near the 1 o` clock position. The same mark exists for the right camshaft pulley only it is on the backing plate near the 8 o`clock position (making it difficult to see). With the crankshaft placed at the zero mark, you can observed where the timing discrepancy exists.

(TIP: Once the right camshaft timing is properly lined up, etch an additional mark on the pulley's face and the backing plate at the 12 o`clock position. This will make it easier to align the pulley for furture adjustments and repairs)

To set the timing correctly, move the crankshaft pulley to 12 deg. BTDC. Being careful to not disturb the position of the crankshaft once it has been moved to that position, remove the crankshaft pulley, lower timing belt cover, timing belt tensioner, and timing belt. Compress the timing belt tensioner and if the original ring pin isn't available to retain the tensioner a small allen wrench can be used to achieve the same results. Line up both camshaft marks and reinstall the timing belt and timing belt tensioner (do not remove the timing belt tensioner tool used to maintain the tensioner piston in a compressed position). When installing the timing belt, be sure to allow the least amount of slack to exisit between the left camshaft pulley and the crankshaft sprocket, but without moving the pulleys.

Next, remove the timing belt tensioner piston retention tool and mount the lower timing belt cover and crankshaft pulley (without fully installing them). Rotate the crankshaft pulley to the 0 deg. mark. If done correctly, moving the crankshaft pulley from 12 deg. BTDC to 0 deg. will remove all remaining slack from the timing belt assembly and the camshaft pulleys and crankshaft pulleys will be lined up with their corresponding marks. Once proper timing has been achieved, install all removed parts.

(Another TIP: I hope it's not necessary, but in case it is, I'll remind you that proper torque of all bolts are necessary as this is an all aluminum engine. Stripping out bolts holes due to over-tightening bolts occurs very easily and become very annoying to deal with [e.g. alternator belts not being able to be tightened completely and constantly squealing every few days, etc.])

Messed up and took head off without putting #1 piston at TDC

Hi there.... I'm assuming you have the head back on. the easiest way is to try and line up the timing marks an the pulleys and install the timing belt. If you have done this and the timing marks line up as they should, you can take the sparkplug out of the #1 cylinder and manually turn the engine over till you can feel air pressure coming out of the plug hole. continue turning the engine till you can't feel anymore pressure. Don't go too far cause then you'll be on the intake stroke and you'll have to turn the engine the opposite way. with the #1 cylinder at TDC, take you distirbutor and cap and figure out what position the rotor should be at for #1 plug. Mark the distributor somewhere where that position is ( where the #1post on the cap should be). Finally insert the distributor and try to get the rotor as close to that position as possible. remember when you install the distributor, The rotor position will move due to the gear set up. Once you have the distributor istalled, you can adjust the distributor for timing by turning it. Hope this helps you out. If you have any other questions, please don't hesitate to ask..

Thanks
Phil
