3) Fill engine coolant into reservoir tank up to upper level.
4) Attach radiator cap and reservoir tank cap properly.
5) Install air vent plug.
6) Warm-up engine completely for more than five minutes
at 2,000 to 3,000 rpm.
7) Stop engine and wait until temperature drops to a safe
level.
8) If engine coolant level drops in radiator, add engine
coolant to filler neck position.
9) If engine coolant level drops from upper level of reser-
voir tank, add engine coolant to upper level.
10) Attach radiator cap and reservoir tank cap properly.

C: CHECKING OF COOLING SYSTEM
1) Remove radiator cap, top off radiator, and attach tester
to radiator in place of cap.
2) Apply a pressure of 157 kPa (1.6 kg/cm
2, 23 psi) to
radiator to check if:
(1) Engine coolant leaks at/around radiator.
(2) Engine coolant leaks at/around hoses or connec-
tions.
CAUTION:
Engine should be off.
Wipe engine coolant from check points in advance.
Be careful to prevent engine coolant from spurting
out when removing tester.
Be careful also not to deform filler neck of radiator
when installing or removing tester.
