A realitively straight forward job -Remove radiator, auxillary belts, fan assy, crank pulley, distributor if motronic, timing cover, would recommend replacing the belt tensioner at the same time. Align timing marks on crank & cam shafts, slacken tensioner, remove & replace belt & tensioner, make sure timing marks still aligned, tension belt with tensioner & lock, rotate crankshaft 2 full turns & confirm both marks still alighned, recheck belt tension & reassemble.
Although straight forward, If not confident I would seek help -youré right if you get it wrong its a sad story.
Good luck!
