ADJUSTMENT COOLANT REQUIREMENTS
Frost precautions and engine protection.
Cooling systemMUST ALWAYSbe filled and
topped-up with solution of water and anti-freeze,
winter and summer.NEVERuse water alone, this
may corrode aluminium alloy.
CAUTION: Do not use salt water otherwise
corrosion will occur. In certain territories
where only available natural water supply
has some salt content use only rain or distilled
water.
Recommended solutions
Anti-freeze:Universal anti-freeze or permanent type
ethylene base, without methanol, containing a suitable
inhibitor for aluminium engines and engine parts.
Use one part of anti-freeze to one part of water.
Anti-freeze can remain in the cooling system and will
provide adequate protection for two years provided
that specific gravity of coolant is checked before onset
of second winter and topped-up with new anti-freeze
as required.
Vehicles leaving factory have cooling system filled
with 50% solution of anti-freeze and water. This gives
protection against frost down to minus 36°C (minus
33°F). Vehicles so filled are identified by a label
affixed to radiator.
NOTE: Should ambient temperatures be
below that stated above refer to
Anti-Freeze Data in Recommended
Lubricants, Fluids and Capacities in Section 09.
Instructions in chart must be strictly adhered to
before driving vehicle.
After the second winter the system should be drained
and thoroughly flushed. Before adding new anti-freeze
examine all joints and replace defective hoses to
make sure that the system is leakproof.
See the 'Recommended Lubricants Fluids and
Capacities' for protection quantities.

Draining
WARNING: Do not remove expansion tank
filler cap when engine is hot. The cooling
system is pressurised and personal
scalding could result.
See coolant requirements before refilling system.
1.Remove expansion tank filler cap by slowly
turning it anti-clockwise, pause to allow pressure
to escape. Continue turning it in same direction
and remove.
2.Remove radiator filler plug and 'O' ring to assist
drainage.

ADJUSTMENT 3.Disconnect bottom hose from radiator. Drain
coolant into a clean container. Reconnect bottom
hose, re-tighten hose clamp.
NOTE: It is not possible to drain all coolant
retained in heater system. It is not
desirable to flush through system, after
draining.
4.Remove engine drain plugs, one each side of
cylinder block, beneath exhaust manifolds. Drain
coolant, refit and tighten plugs.
5.Pour correct solution of water and anti-freeze
into expansion tank until radiator is full.
6.Start engine, run it until normal operating
temperature is attained, topping up as
necessary.
7.Refit radiator filler plug and 'O' ring, with new 'O'
ring if required. Tighten to
6 Nm.
8.Fit expansion tank filler cap.
9.Allow engine to cool, check coolant level. Finally
top up expansion tank until level reaches seam
of expansion tank.
