Timing Belt: Fundamentals and Basics
POSITIONING CRANKSHAFT TO #1 TDC, Compression
NOTE: If the timing belt is broken, pre-position only the crankshaft and ignore references in this article to compression stroke, camshaft, and
Timing belt installation alignment marks correspond to the crankshaft positioned at #1 Top Dead Center (TDC), during the compression stroke.
The alignment marks may be dirty and difficult to locate. Pre-positioning the crankshaft will make it easier to locate the marks.
Remove the distributor cap and observe the position of the rotor.
Using the crankshaft bolt, rotate the crankshaft until the distributor rotor is nearly pointing towards the #1 cylinder position.
Then slowly rotate the crankshaft until the timing indicator is pointing at the "0"/TDC degree mark.
NOTE: Remember that the crankshaft rotates twice for every rotation of the camshaft. The rotor must be pointing towards #1 cylinder terminal
