[xj] cooling-related Qs

Two questions:

  1. Is there supposed to be a gasket under the triangular flange for the water
    filler cap at the top of the engine – all I found was an old 1.25" o-ring in
    a seat at the neck?

  2. I have the fan, top shroud and clutch off, now how do I get the lower
    shroud up and out? Should I remove a hose or two?
