I am trying to remove the coolant apparatus so I can get to the engine better for a refresh.
There is a metal pipe running across block under the down pipes to give water inlet to each cylinder.
I have released the two 10mm bolts that hold it to the block. One above pipe, one below.
Diagram shows just one o ring 92055-1282 should now be holding the 4 connector pipes in place.
But it seems mighty stuck if that is the case.
Anyone had any success getting this pipe off without wreckage? Can't see any ideas in the Factory Service Manual.
The offending pipe is code 39192-1146. See here -
