(LIQUID COOLING SYSTEM)
04-06-3
TYPICAL — OPEN THERMOSTAT AND WARM ENGINE
1. To radiators
2. From cylinders
These 2 functions have the advantage of prevent-
ing a massive entry of cold water into the engine.
2, Coolant Tank
The coolant expands as the temperature (up to
90-100°C (195-212°F)) and pressure rise in the sys-
tem. When the limiting system working pressure
(cap) is reached (90 kPa (13 PSI)), the pressure re-
lief valve in the pressure cap is lifted from its seat
and allows coolant to flow through the overflow
hose.
COOLING SYSTEM REFILLING
PROCEDURE
Recommended Coolant
Use a blend of 60% antifreeze with 40% water.
Do not reinstall pressure cap.
System Capacity
Refer to TECHNICAL DATA 10.
Refilling Procedure
Lift front of vehicle until the tunnel is horizontal.
With engine cold, refill coolant tank up to cold lev-
el line. Wait a few minutes then refill to line. Install
pressure cap. Run engine until thermostat opens
then stop engine. Refill up to line.
To make sure coolant flows through radiators,
touch them by hand. They must feel warm.
Put back front of vehicle on the ground.
When engine has completely cooled down, re-
check coolant level in coolant tank and refill up to
line.
1. Coolant tank
2. COLD LEVEL line
Check coolant concentration (freezing point) with
proper tester.

CAUTION
To prevent rust formation or freezing condi-
tion, always replenish the system with 60%
antifreeze and 40% water. Pure antifreeze
without water freezes. Always use ethyl-
glycol antifreeze containing corrosion inhib-
itors specifically recommended for alumi-
num engines.
