System sealing check
- Check the proper circuit sealing when it is under
pressure and at the temperature.
- For a more accurate check, wait until the system
has cooled down since small leaks may not be
visible due to evaporation
- The water pump is provided with a drainage hole
in case of leaks from the cooling system mechan-
ical seal, or from the shaft sealing oil guard.
- If coolant or oil leaks are detected, inspect the pump (see Flywheel cover chapter).
N.B.
DO NOT USE OILS OR GREASES WHILE MOUNTING THE COOLING SYSTEM. FAILURE TO OB-
SERVE THIS PRECAUTION WILL IRRETRIEVABLY DEFORM THE SEALING GASKETS.
