Coolant, Draining
WARNING!
Do not open the coolant filler cap when the engine is
warm, except in emergencies, this could cause serious
personal injury. Steam or hot fluid could spray out.
IMPORTANT!
On engines which are to be put in storage, the engine
cooling system should
not
be drained. The coolant
contains corrosion inhibiting additives.
1 Stop the engine before draining the cooling sys-
temand remove the expansion tank cap.
2 Remove the filler cap (
1
).
NOTICE!
Do not open pressure cap (
2
).
NOTICE!
On TWD1643GE both the pressure cap on
the expansion tank (
1
) and the filler cap on the radiator
(
2
) are opened.
3 Open all drain points. Drain the coolant from the
radiator and engine block, using the drain hose.
The drain nipples are situated under the radiator on
the right side of the engine block.
4 Check that all coolant drains out. Deposits may be
found inside the drain plug/tap, and need to be
cleared away. There is otherwise a risk that coolant
could remain and cause frost damage. Check
whether the installation has any further taps or
plugs at the lowest points of the cooling water pipes.
5 Shut any taps and check that the spring-loaded
covers on the nipples close completely. Install the
rubber plugs.
Charge Air Cooler, External
Cleaning
Remove guards as necessary, to access the radiator.
Clean with water and a mild detergent. Use a soft
brush. Be careful not to damage the radiator vanes.
Reinstall removed parts.
IMPORTANT!
Do not use a pressure washer.
