TDC is when the #1 piston is at the top if it's cycle in the cylinder on the compression stroke. When that happens the rotor on the distributor will be pointing at the spark plug wire for #1 cylinder. Remove the spark plugs to make turing the engine over easier. Rotating the engine can be done with a wrench on the end of the crankshaft or with a "remote starter" switch connected to the starter motor and then usign the wrench or by pulling on the alternator belt which you have removed.
I will try to remember to bring my Haynes manual to the public library tomorrow so I can type in the essetnials of lining up the camshaft and crankshaft, and releasing and repositioning the tension pulley. As the pervious poster pointed out, the Haynes repair manual has photos which you would find helpful. I was able to replace the timing belt on my carburetted '89 Festiva with little prior auto repair experience.Original owner of silver grey carburetted 1989 Festiva. 105k km as of June 2006. 140k km as of June 2021.

You say everything has been removed in order to replace the belt so i will skip most of the removal part. To save time I will not get anal about spelling mistakes. This is from the Haynes manual. I've used it.
1. Removal.
a) Before removing the old belt turn the crankshaft to bring the engine to top dead centre to align the crankshaft and camshaft timing marks (sorry, did you say the old belt broke? oh well, skip that part)
b) loosen the tensioner (the floating wheel restign on the belt, oh, your belt broke?), pull it back, and tighten it to keep it out of the way
c) pull the old belt off, or what's left of it
2. Installation.
a) Clean the area under the timing belt cover
b) Align tyhe crankshaft and camshaft timing marks as shown in the photographs (this is in the Haynes manaul). What the photos show are: On the camshaft there are two marks which need to be at 12 o'clock and 3o'clock. There is a pointer on the engine at 12 o'clock to align the camshaft with. On the crankshaft there is a notch which aligns with a pointer on the engine at 12 o'clock. Slip the new belt over the camshaft and crankshaft pulleys with no slack on the side opposite the tensioner. Don't move the pulleys when doing this. the timing makrs need to stay lined up.
c) Loosen off the tension roller and let it rest on the belt. The spring will put the right amount of tension on the belt.
d)Rotate the engine a couple of times and check the timing marks are still aligned. If it sticks do not attempt to force it because the valves may be interferring with the pistons. (I don't know why Mr Haynes writes that for a freewheeling engine, ie no interference) If the timing marks are not still aligned go back to step b).
e)Double check everything (I made that part up) and put all the stuff back on the engine. You're done. Cross your fingers, turn the engine over a few times with the starting motor. If everything feels right and your astrologist says the signs are favorable, start your engine.
Best of luck.Original owner of silver grey carburetted 1989 Festiva. 105k km as of June 2006. 140k km as of June 2021.
