Filler cap
5. Clean the cooling system filler cap and inspect the
gasket. If the gasket is damaged, discard the old
filler cap and install a new filler cap. If the gasket is
not damaged, use a suitable pressurizing pump in
order to pressure test the filler cap. The correct
pressure is stamped on the face of the filler cap. If
the filler cap does not retain the correct pressure,
install a new filler cap.
6. Start the engine. Inspect the cooling system for
leaks and for correct operating temperature.
Coolant Drain Plug for Cylinder Block
Illustration 43 g03487216
Typical example
The coolant cylinder drain plug (1) has a special
concave bead of sealant in position (2) on the drain
plug. The drain plug may be reused, but if the sealant
is damaged or missing the drain plug must be
replaced. Ensure that the sealing surface (3) in the
cylinder block is clean and free from dirt, before
installing the drain plug.

distributor.

Coolant Level - Check
Pressurized System: Hot coolant can cause seri-
ous burns. To open the cooling system filler cap,
stop the engine and wait until the cooling system
components are cool. Loosen the cooling system
pressure cap slowly in order to relieve the
pressure.
Check the coolant level when the engine is stopped
and the engine has cooled.
NOTICE
When any servicing or repair of the engine cooling
system is performed, the procedure must be per-
formed with the engine on level ground. This proce-
dure will allow you to check accurately the coolant
level. This procedure will also help in avoiding the risk
of introducing an air lock into the coolant system.
1. Remove the cooling system filler cap slowly in
order to relieve pressure.
2. Maintain the coolant level at the maximum mark
that is correct for your application. If the engine is
equipped with a sight glass, maintain the coolant
level to the correct level in the sight glass.
