yeah i thought so too, just like the eb i6 (according to my gregories). that was till i realised that the water pump on single serpentine belt windsors (like my eb) turns the the other way, meaning that a right hand thread would be less likley to undo itself. i remember this cos i felt like a real git after spending 1/2 hr tightening it when i wanted to undo it
the tool i made was a flat steel bar that i drilled 2 holes in and bolted it to the pulley with 2 of the pulley bolts. needed to be long for leverage tho after all that accidental tightning
so right hand thread on an e-series 5.0L, left on an 3.9 or 4.0L
