Timing belt?

Any electrical connectors removed in process? Is there an engine miss?

See text and pics for instaltaion.

Hi, Christa,

I'm not sure what happened, but we have had other posts added to yours. I have to be honest, I'm not sure I understand what you are asking. So, I decided to add all the directions for replacement with pics to help.

Here are the directions for belt replacement. The attached pics correlate with the directions.

If you look at the next to the last pic below, you will see where the timing marks all need to align for proper timing.

Let me know if that answers your question. Please let me know how things are going or if you have other questions.

Christa,

This thread has shown up again but there was no reply from you. Usually, I only get the indication if you replied to me. I'm just checking to see if something didn't go through for you.

Joe

Christa,

If you are certain the timing is correct, it sounds like there may be a bent valve stuck open and hitting which is stopping the engine from turning. What happens if you turn it the opposite direction. Does it go further before stopping?

Let me know.

Joe
