Where can I find the TDC mark on my car?
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.
When to put engine in or out of TDC?
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.
Where does the crankshaft go when setting to TDC?
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 1 cylinder located at TDC?
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. Personally, I don’t care for this method because if the groove is not centered in the opening, the timing can be off ±1 tooth.
