If you have trouble locating the TDC mark from above, there is a 5 mm wide groove in the flywheel which can be used to locate TDC as well. It will appear in an opening in the bottom of the clutch housing near the starter. When the groove is centered in the opening the #1 cylinder is at TDC.
Full Answer
How to tell if the engine is at TDC?
If the engine is not in the car and the clutch housing is removed, the "OT" scribe mark on the flywheel will line up with a cast mark on the back of the upper crankcase section when the #1 cylinder is at TDC.
How do I lock the engine at TDC position?
If the crankshaft pulley bolt needs to be removed or it is important that the engine remain at the TDC position, you'll need to install the "engine in" flywheel lock (9206). There is also an "engine out" flywheel lock (9130) which is used if the engine is on an engine stand.
How do I find the TDC mark on my flywheel?
If you have trouble locating the TDC mark from above, there is a 5 mm wide groove in the flywheel which can be used to locate TDC as well. It will appear in an opening in the bottom of the clutch housing near the starter. When the groove is centered in the opening the #1 cylinder is at TDC.
Where do you put the camshaft mark on a timing belt?
The mark on the camshaft sprocket should be aligned with the mark on the inner timing belt cover or the edge of the cylinder head. With the distributor cap removed, the rotor should be pointing toward the No. 1 mark on the rim of the distributor housing.
Where is the timing mark on crankshaft?
A timing mark is an indicator used for setting the timing of the ignition system of an engine, typically found on the crankshaft pulley (as pictured) or the flywheel, being the largest radius rotating at crankshaft speed and therefore the place where marks at one degree intervals will be farthest apart.
How much does it cost to change a VW timing belt?
Belts themselves aren't that expensive. The real cost is in the labor, because a lot of parts need to be disassembled to get to the belt. Shopping around to get a few quotes is your best bet to get the best deal, but you can expect to pay anywhere from $409 to $919 (including parts and labor).
When should a VW timing belt be changed?
We recommend changing your cambelt once every four years for cars registered before September 2009, and every five years for cars registered after. If you reach the recommended mileage limit before 4 or 5 years, you may need to change the cambelt sooner. For more information, contact your local retailer.
What causes timing belt to break?
The tensioner that keeps the belt taut is pressurized by the engine oil. If the tensioner has no oil pressure, the belt will become loose and possibly disengage from the pulleys and/or break. If the camshafts don't have enough oil pressure to operate properly, they will also lock up, causing the timing belt to break.

How do I check my timing belt?
To inspect the belt, first look at the outside of the belt to see if any tiny cracks are forming. The timing belt is a very strong metal-reinforced belt with rubber on the outside. The rubber should be fairly smooth, with no chunks missing or massive cracking.
Is there any warning before timing belt breaks?
There are some surefire warning signs you should look out for that could indicate that your timing belt is about to fail: this includes ticking noises, car not starting, piston misfires, exhaust smoke, excess vibrations and oil leaks.
Do valves always bend when a timing belt breaks?
A non-interference engine provides clearance between the valves and pistons, so if the timing belt breaks, you might end up with bent valves, and you might have to have your cylinder heads rebuilt, but the engine isn't likely to be destroyed.
What happens when VW timing belt breaks?
When the timing belt breaks, the crankshaft will continue to spin at 1000 rotations per minute, while the camshaft will stop turning. As a result, the pistons will continue to rise and fall in their cylinders and can in some instances strike the valves.
There are several jobs on your car that you need to set the engine at Top Dead Center or TDC
This article will show you how to set TDC for the head by using the crank and timing belt. The crank and head are connected by the timing belt. If you are replacing the timing belt you will be removing the timing belt cover as well as the motor mount to set both the crank and head at TDC separately.

Figure 1 If you do not have an after market air induction system you will need to remove the engine cover. Please see our article on engine cover removal for additional assistance.
Where to install timing belt?
Install the timing belt, with the arrow pointing in the direction of rotation, on the crankshaft sprocket, the water pump sprocket and the camshaft sprocket.
How to align timing belt on 8 valve engine?
On 8 valve engines, the notch on the crankshaft pulley should align with the dot on the intermediate shaft sprocket. Loosen the locknut on the tensioner pulley and turn the tensioner counterclockwise to relieve the tension on the timing belt. Slide the timing belt from the spro ckets.
When setting the engine to TDC on the compression stroke for cylinder #1, must you realize that the crankshaft?
When setting the engine to TDC on the compression stroke for cylinder #1, you must realize that the crankshaft rotates twice for every single rotation of the camshaft. So, if you simply set the crankshaft to TDC without looking at the position of the camshaft, you may actually be at TDC on the exhaust stroke for cylinder #1.
Where is the alignment mark on a camshaft?
The camshaft sprocket alignment mark is visible through the opening in the front distributor housing cover just above the distributor cap.
What is the alignment mark on a camshaft sprocket?
Note: If this is being performed by one person, the alignment mark on the camshaft sprocket can be used to determine when the engine is close to Top Dead Center (TDC). However, the flywheel should be used for final alignment in case the timing is off slightly. The camshaft sprocket alignment mark is visible through the opening in ...
Where is the cast mark on the flywheel?
If the engine is not in the car and the clutch housing is removed, the "OT" scribe mark on the flywheel will line up with a cast mark on the back of the upper crankcase section when the #1 cylinder is at TDC.
Can you rotate a crankshaft?
Note: The crankshaft should not be rotated, manually or otherwise, unless the timing belt is installed with timing properly set or the camshaft housing assembly removed. This is done to prevent valve/piston damage. Using the 15/16" or 24 mm deep socket and ratchet, rotate the engine in the clockwise direction using the crankshaft pulley bolt on ...
