Hello all! I apologize that my first post is made to ask for help, but I’m at a loss. I’m replacing the timing belt and tensioner on my daughter’s 2004 Sonata with the 2.4 turbo. I have the balance shaft timing marks lined up.... but I do not see timing marks anywhere on the crankshaft sprocket. There are two marks on the back of the sprocket, nothing on the front. Any info or referral to an information source would be very much appreciated.
