7) Remove reservoir tank and remove cap from reservoir tank
and pour out any fluid, scrub and clean inside of tank with soap
and water.
Flush it well with clean water and drain. Reinstall tank.
8) Add 50/50 mixture of good quality ethylene glycol antifreeze
and water to radiator and tank.
Bleed air from cooling system by disconnecting heater breath-
er hose and loosening thermostat cap bleeder bolt, and add
coolant to radiator until coolant comes out from thermostat cap
bleeder hole. Then tighten thermostat cap bleeder bolt.
Tightening Torque
(a): 3.0 N·m (0.3 kg-m, 2.2 Ib-ft)
9) Fill radiator to the base of radiator filler neck and reservoir tank
to “FULL” level mark. Reinstall reservoir tank cap.
10) Connect heater breather hose.
11) Run engine with radiator cap removed, until radiator upper
hose is hot. Add coolant to radiator until level reaches the bot-
tom of filler neck.
12) Stop engine and install radiator cap, making sure that the ear
of cap lines is parallel to radiator. Add coolant to reservoir
when engine cold.
13) Repeat step 8) to 12) accordingly when air is still in cooling sys-

WATER PUMP BELT TENSION
1) Inspect belt for cracks, cuts, deformation, wear and cleanliness.
If it is necessary to replace belt, refer to “Generator (Water
Pump) Belt” in CHARGING SYSTEM section for procedure.
WARNING:
Disconnect negative cable at battery before checking
and adjusting belt tension.
See “WARNING” described in “COOLING SYSTEM
SERVICE”.
2) Check belt for tension. Belt is in proper tension when it deflects
6 to 8 mm (0.24 – 0.31 in.) under thumb pressure (about 10 kg
or 22 Ib.).
Belt tension “a”: 6 – 8mm (0.24 – 0.31 in.) as deflection
NOTE:
When replacing belt with a new one, adjust belt tension to
5 – 7 mm (0.20 – 0.28 in.).
3) If belt is too tight or too loose, adjust it to proper tension by dis-
placing generator position (Refer to Section 6H).
4) Tighten belt adjusting bolt and generator pivot bolts.
5) Connect negative cable at battery terminal.
