The timing marks should be on the driver's side of the car down by the harmonic balancer on a small plate. theres usually a "pointer" on the drivers side. its attached with two of the front cover bolts. When you look down at your Harmonic balancer there should be something about it that you see that looks kinda like saw teeth with numbers in the gaps. The zero or line whichever year you have should be on the Harmonic balancer.

The timing marks should be found on a little metal plate directly above the harmonic balancer.
