        You should check the flange for the air bleeding hose on the rear
right side (just below the altenator). If you still have the plastic flange,
it may have warped and allowed coolant to leak. Also, before doing anything
too drastic, you might pull the push tube protector plates which will give
you a better idea of where the coolant is coming from. If you can see coolant
on top of the head (under all the air intake stuff), even just a film of green
sticky liquid, then I believe you have a gasket problem... Otherwise it
could be the flange, or possibly the hose in the front which goes to the
coolant distribution manifold.
