CHECK AND REPLACEMENT OFENGINE COOLANT1. CHECK ENGINE COOLANT LEVEL AT RESERVOIR TANK

The coolant level should be between the ”COLD” and ”LEV-EL” lines at normal temperature. (20°C, 68°F)

If low, check for leaks and add coolant up to the upper(COLD) level line.

HINT: If the coolant temperature is higher than normal tem-perature, the coolant level should be higher than upper levelline.

2. CHECK ENGINE COOLANT QUALITYThere should not be any excessive deposits of rust or scalesaround the reservoir tank cap or radiator filler hole, and thecoolant should be free from oil.If excessively dirty, clean the coolant passages and replacethe coolant.

3. REPLACE ENGINE COOLANT(a) Remove the reservoir tank cap.CAUTION: To avoid the danger of being burned, do notremove the cap while the engine and radiator are still hot.Scalding fluid and steam can be blown out under pres-sure.(b) Remove the filler plug from the water inlet housing.

(c) Drain the coolant from the radiator and engine draincocks.

(d) Clean the coolant passages.(e) Close the drain cocks.Torque (Engine drain cock):

25 N⋅m (250 kgf ⋅cm, 18 ft ⋅lbf)

(f) Following the procedure shown below, open the watervalve of the heater.(1) Ignition SW ON(2) A/C Blower Motor ON(3) Using the A/C Temp. Control Button, raise the settemp. to the highest temp.

(4) Check that the lever of the water valve is in the posi-tion shown in the illustration.

(g) Slowly add coolant to the water inlet housing until it isfull.

• Use a good brand of ethylene–glycol base coolantmixed according to the manufacturer’s directions.

• More than 50% ethylene–glycol solution (But not morethan 70 %) is recommended.

NOTICE: Do not top up with water only.

(h) Install a new gasket and tighten the plug of the waterinlet housing.

Torque: 44 N ⋅m (450 kgf ⋅cm, 33 ft ⋅lbf)

(i) Slowly add coolant to the reservoir tank.HINT: The coolant level in the reservoir tank will drop after awhile. Keep adding coolant until the coolant level no longerdrops.

(j) While the engine is idling (for at least 10 mins.), addcoolant (approx. 4 liters) up to the reservoir tank inlet tojust below the overflow pipe. Securely tighten thereservoir tank cap.

(k) Stop the engine after racing it for five minutes at2,000–3,000 rpm.

(l) After the coolant drops, remove the reservoir tank capand add coolant up to the reservoir tank inlet to justbelow the overflow pipe. Securely tighten the reservoirtank cap.

Capacity (w/ Heater):10.6 liters (11.2 US qts, 9.3 Imp. qts)

(m) Check for leaks.
