The crankshaft pulley bolt on your 1998 Chevrolet Metro should be standard right hand thread - clockwise to tighten and counter clockwise to loosen.
The bolt is right hand thread. It is hard to hold the engine from turning to remove this bolt. I use an impact to do it and I have had to use a 3/4" one on some.
