Does anyone know the procedure for fully refilling the coolant on this engine. The workshop manual is no help either. Thanks, Leon
That may be something specific to Range 4 engines with Manicoolers.

My 1976, 6-354M's are pretty straight forward. Just fill the cooling system to the level on the expansion tank, with cap on bring up to operating temperature and then check the fill level.
