I need a diagram to show me how to install my timing belt in my 2003 Subaru Outback.

tensioner for a/c belt, alternator, timing belt? you need to be more specific...

This is the best i could find.

Hi,
This is the belt diagram you need.

Here you go

Do not attempt this unless you are nowhere near a Subaru dealer. If you have defective seat belts, take it to the dealer, they have a lifetime warranty as long as you did not tear them up or something like that. I just took in a 99 Forester that had a belt that would not retract and they fixed it under the warranty for free.

Well the timing belt should be changed every 60,000 miles or every 4 years.Whichever comes first.

the timing marks are on the camshaft pulleys and there are 2 notches on each pulley> they line up with 2 marks on the engine block for each pulley> and the crankshaft has a notch that lines up with a mark on the engine block aswell> pluss the new timing belt will have white marks on it that will line up with all of the marks on the pulleys when they are in the right place so its nearly impossable to do it wrong

Hope this helps out,
