I finally got around to changing the belt today.
I don't remember where I read that it can be changed without removing the splash guard, but I don't see how that is possible. Someone would have to have some paper-thin monkey hands to guide the belt around the pulleys properly with the splash shield in place. At least that is what I observed on the 2003 ZX2. The splash shield that needed to be removed was the right side one, held in place with 7 bolts with 10mm heads.
And I didn't have a good breaker bar with me, but that would be the best thing to use on the tensioner. I was at someone else's house with a minimum of tools in my trunk. What I had with me was adequate, but a long handled breaker bar would have been easier. I used a regular Craftsman 3/8 drive ratchet, short half inch (or 13mm) socket on the tensioner and a one inch box wrench for leverage. Crude but effective. I had a nice big jack handle, but it was too long to fit under the car and the ratchet was too short to use from the top. I improvised. I adapted. I overcame the odds. I used a bigger wrench.
