i changed my 2.2 timing belt with no problem.

my cousin has a few year old 2.5 liter wagon that's over due for a belt change. are the procedures similar at all?

on EJ22 engine is SOHC and EJ25 is DOHC which means the timing belt is bigger/longer than EJ22's belt. But the change over of belts should be simular.

not all EJ25 are DOHC, there were tons of EJ251 motors that were SOHC.

Having changed head gaskets on a 97 2.5 DOHC, I did a fair amount of research. The Phase II 2.5 engine, which started in 99 or 2000, is a SOHC. The DOHC version ended at Phase I.
The belt change procedure is essentially the same, but you have to line up marks on 4 cam gears, not just 2. The left side cams are under tension when lined up and if they move just a little they will spin. It is a real pain to get them all to stay in the right place and get the belt on, it usually takes me 3-4 attempts. Make sure you double check before letting the tensioner loose. I thought I had it a couple of times only to find out I was one tooth off on one gear.
Good luck!

Just remember, the 2.5L is an interference type engine. There is ZERO margin for error. Last week someone on this board posted that he destroyed his 2.5L engine replacing the timing belt.
