So my timing belt is on, cam marks line up, bottom end is at TDC
And reading these recent timing belt posts now has me nervous. How can I tell before I button it up if I have all the slack on the tensioner side of things? It was VERY hard to get on, and both sides feel pretty tight, almost the same tightness and I guess I expected to have more tension on the water pump side for now since I haven't removed the pin on the tensioner yet.
I did count teeth and mark the belt but it appears I may have erased the marks while fighting with the belt. Any thoughts?

I recall reading that you can turn the engine through a full cycle by and, slowly. If there is any
resistance, time to check your work... Best to do with the plugs removed so you don't have to fight compression.

TDC marks
Does the 225TT not have a TDC mark on the block with the crank pulley removed? On my ATC 180TT there is a tooth on the crank sprocket that is white and there is also a marker on the block that was cast in from the factory. This is what I used to line up TDC and the marks up top lined up with this as well (when belt was still on). Still fighting to get my new belt on though

Did you release the tensioner already? Just turn the crank a couple of 360's to make sure you are
reading a tensioned and stretched belt. It it still lines up, you're good to go. Pull the pin, and lock it down.

pretty much useless IMO unless you are dynoing it with a load based dyno...
or remove head and use machine calipers to measure the highest points of the piston and valves, remark timing alignments and then do the math from there.
