I've done many transverse engine timing belts of several makes and models over the years.
It seems the more of them you do, the more they all seem the same or similar.
One of the most important tips for me is to match mark everything on the timing system prior to disassembly.
I don't bother with top dead center alignment anymore. I remove the starter and install a universal flywheel lock tool to prevent movement. It bolts on using the starter bolt holes.
I use a paint marker and put alignment dots on the belt; cams/crank pulleys and housing.
I count belt ribs between the dots and mark the new belt in the same spots.
Then reinstall aligning the marks. This puts all the slack back over by the tensioner where it should be.
Once the belt is installed, I remove the flywheel lock tool and roll the motor by hand a few times to ensure the marks come back into alignment.
This will tell me if I'm off a tooth and it's very important before starting the engine, especially interference engines, but it's good to get into this habit on all types.
This method just works for me and I've never had any issues on any engine timing belt replacement.
