I have an 85 4000s that followed me home last week, so I'm going to replace the timing belt and water pump. I don't have a bently for this model, but have done it 5 times on the 5 cylinder 5000's. I'm having trouble getting the AC belt off, and where are the timing marks on the cam sprocket and what do they line up too?

Theres a punch mark on the cam sprocket and it lines up to the right side of the valve cover. To make it easier also, pull the plug and youll see when its there.

Front or backside of cam sprocket? I have seen the one in front.

It lines up with the top of the valve cover, just like the 5cyl does.

It's been a long time since I've done the timing belt on a 4cyl but don't you have to line up timing marks on the cam sprocket and the flywheel? Thats what bently says to do on the 5cyl.

He was asking where the timing mark was on the cam sprocket.

if you put it on flipped around (it will go on that way too)your timing marks will line up but your cam will be off,,ask Jeff Doble about that. Best bet would be to put a paint mark on the mark on the backside so there's no confusion.
