Radiator Cap; Coolant Reservoir - Suzuki Jimny Service Manual

Radiator Cap

A pressure-vent cap is used on the radiator. The cap contains a
pressure valve (1) and ventilation valve (2).
The cap has its face marked 1.1, which means that its pressure
valve opens at 1.1 kg/cm
NOTE:
Do not remove radiator cap to check engine coolant
level; check coolant visually at the see-through coolant
reservoir.
Coolant should be added only to reservoir as necessary.
WARNING:
As long as there is pressure in the cooling system, the
temperature can be considerably higher than the boiling
temperature of the solution in the radiator without caus-
ing the solution to boil. Removal of the radiator cap while
engine is hot and pressure is high will cause the solution
to boil instantaneously and possibly with explosive force,
spewing the solution over engine, fenders and person
removing cap. If the solution contains flammable anti-
freeze such as alcohol (not recommended for use at any
time), there is also the possibility or causing a serious
fire.

[D]: At vacuum relief

Coolant Reservoir

A "see-through" plastic reservoir (1) is connected to the radiator
by a hose.
Coolant level should be between "FULL" level mark (2) and
"LOW" level mark (3) on the reservoir.
Coolant should be added only to the reservoir as necessary.
NOTE:
When installing reservoir cap, set arrow marks (4) on the
reservoir and cap as the figure.
