Section 04 ENGINE
Sub-Section 08 (LIQUID COOLING SYSTEM)
04-08-5
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
system. When the limiting system working pres-
sure (cap) is reached (90 kPa (13 PSI)), the pres-
sure relief valve in the pressure cap is lifted from
its seat and allows coolant to flow through the
overflow hose into the overflow coolant tank.
When the system temperature drops, the coolant
contracts in volume and the pressure in the cool-
ant tank is reduced. The coolant in the overflow
coolant tank will then flow back into the coolant
tank through the vacuum relief valve in the pres-
sure cap.
COOLING SYSTEM REFILLING
PROCEDURE
Recommended Coolant
Use a blend of 60 % antifreeze with 40 % water.
Do not reinstall pressure cap.
CAUTION : To prevent rust formation or
freezing condition, always replenish the
system with 60 % antifreeze and 40 % water.
Pure antifreeze without water freezes. Always
use ethyl-glycol antifreeze containing corro-
sion inhibitors specifically recommended for
aluminum engines.
System Capacity
Refer to TECHNICAL DATA 10.
Refilling Procedure
With vehicle on a flat surface, engine cold, refill
coolant tank up to cold level mark. Wait a few min-
utes then refill to mark. Install pressure cap. Run
engine until thermostat opens then stop engine.
Refill up to mark.
To make sure coolant flows through radiators,
touch them by hand. They must feel warm.
Reinstall pressure cap.
When engine has completely cooled down, re-
check coolant level in coolant tank and top up if
necessary.
Check coolant concentration (freezing point) with
proper tester.
