What are the timing marks for a 1997 Cadillac Catera?
The rear metal timing belt cover has a notch behind each of the
camshafts. Use these notches to put the mark on the camshaft gear
starting from passenger side with the #1 on the camshaft gear, then
2,3, & 4 in order. On the crankshaft you must remove the 6 bolt
holding the pulley and remove pulley so that you may access the
mark on the bottom gear. One you locate that mark that one should
be aligned at 6 o'clock position with a recess on the front right
underneath that gear. At this point cylinder #1 is at top dead
center. If you had removed the timing Gears, Install the gear so
the alignment pin on the cam is in the correct, numbered alignment
slot on the cam gear, to prevent a 180 degree out cam timing.
