Thanks for the response Charles. The boot is pushed out and judging by
the amount of coolant that came out of the anode area when I removed
the tube/lens assembly from the light box, it has probably been leaking
slightly for a little while.

I will let you know how I make out.

You may not have too bad a problem. Was the expansion Boot pushed out?
(Boot & ring With 4 1/4 head screws ) If it was some of these sets
left factttory OVERFILLED with coolant. Lay tube & lense on bench with
this exp boot up, remove the 4 screws If coolant runs out it is
overfull Lower level to about 1/2 to 3/4 inch below point where screws
go in. Clean every thing with alachol Watch for leaks. If the Boot has
a hole in it email me & I send part# for replacement boot Charles
