Tdc timing marks for elantra 1.8i - 1997 Hyundai Elantra

You have 2 marks on the pully, one for TDC or top dead centre. The other mark is the timing mark for when the engine is running, this should be before TDC.

Not to worry. The cam gear has marks on it already. When the cams are aligned at Top Dead Center (TDC) the keway for the pulley will be pointing UP and the marks on the edge of the pully will be lined up with the valve cover sealing surface of the cylinder hed. (See picture below)

remove cam sensor clean it put it back in try the car if it still not right replace the sensor you may need to replace crank sensor as well when did it last have a timing belt replaced ?if its got over100 ,000 km on it and hasnt been done i would have it done if the belt brakes it can be fatal for the engine if its old then it may have jumped a tooth wich will put the cam timing out i would look there first turn the engine over by hand till the timing mark on the crank pulley is showing tdc remove the top half of the timing belt cover remove no1 spark plug use a suitable probe to check that no1 piston is at the top if so check the marks on the cam gears are in line with there marks if all marks line up the valve timing is ok

remove the valve cover,next the camshaft gear cover.allign the pulley to 0 or tdc.then check the camshaft pulley timing mark.if its alligned already..your ready to change the belt.

the camshaft is the dot on the sprocket there is a small mark behind it on the cover 12 oclock the crank there is a mark on it look to the ten oclock number 1 tdc you will see the mark

hi from uk the cambelt timing marks at TDC are as follows--the crank gear mark is lined up with mark on front of engineblock at approx 10-30 am position the marks are clear as you look ? the cam coghas a dot/pop mark just below teeth this mark is at top ie 12-0'clock position now on cam cog you will also see s hole drilledon the cog web also at 12-o/clock if you look thro this hole (use a mirror ?) the hole lines up to a grooved vertical line at the rear which is on front of engine at this point you fit belt fron crank pully anti clockwise round cam cig then reset tensioner when marks are rechecked with belt fitted/tensioned ? turn engine manually two full rotations clockwise then recheck all mark line up again ? then re assemble ? c/shaft pully bolt tightens to=170-180 Nm hope you notice that the new belt is marked as to its rotation with arrows hope this helps ?best wishes from uk

8 degrees before tdc

dear friend-if your mark at the bottom is on TDC then that is fine,there is a 8mm hole in the top sprocket.alighn the hole with the mark on the cylinderhead,put belt on and tention turn ones around and lighn up marks.re-assemble.

there is a hole in the cam sprocket, when it is at about 12 oclock it chould line up with a groove machined into the head. That is tdc for cam, when lower timing cover removed, mark on crank sprocket should line up with mark on block.

this is for the crank pulley timing marks .....
