♦ The plastic bases supplied as a protection
for the open valves must not be removed until
just before fitting on the cylinder head.
♦ If the cylinder head is replaced, the entire
system must be filled with fresh coolant.
♦ Always replace seals and gaskets when car-
rying out removal and installation operations.
