question Ferret: induction manifold drain tap

[smashycrashy]

So I am trying to change out the coolant in my Ferret, is there a trick to getting the induction manifold drain tap open? Its in an akward spot and I cant tell if it moves, up down, left right, etc. My attempts of blind manipulation have failed so I was wondering if anyone had advice.

did my coolant drain by removing drain plug from hull plate to the right of starter handle hole have lots of buckets then flush with hose put drain plug back in fill system with water run ten minutes ,wait ten mins ish carefully remove rad cap drain again drain plug back in fill 50/50 mix with old style blue antifreeze run with cap off to remove any air top up level then cap on ,if there is to much fluid in system they will spit it out from l/h side port normal operating temp is 185 f on mine beware if yours is gong over 200 f as system aint pressurising ie u have a leak:D
