Draining and Refilling Cooling
System
Before draining the cooling system, inspect the system
and perform any necessary service to ensure that it is
clean, does not leak and is in proper working order. The
engine coolant (EC) level should be between the ªMINº
and ªMAXº lines of reserve tank when the engine is cold.
If low, check for leakage and add EC up to the ªMAXº line.
There should not be any excessive deposit of rust or
scales around the radiator cap or radiator filler hole, and
the EC should also be free from oil.
Replace the EC if excessively dirty.
1. Completely drain the cooling system by opening the
drain plug (2) at the bottom of the radiator.

2. Remove the radiator cap.
WARNING: T O AV O I D T H E D A N G E R O F B E I N G
BURNED, DO NOT REMOVE THE CAP WHILE THE
ENGINE AND RADIATOR ARE STILL HOT.
SCALDING FLUID AND STEAM CAN BE BLOWN OUT
UNDER PRESSURE.
3. Disconnect all hoses from the EC reserve tank.
Scrub and clean the inside of the reserve tank with
soap and water. Flush it well with clean water, then
drain it. Install the reserve tank and hoses.
4. Refill the cooling system with the EC using a solution
that is at least 50 percent antifreeze but no more than
70 percent antifreeze.
5. Fill the radiator to the base of the filler neck.
Fill the EC reserve tank to ªMAXº line when the engine
is cold.
6. Block the drive wheels and firmly apply the parking
brake. Shift an automatic transmission to ªPº (Park)
or a manual transmission to neutral.
7. Remove the radiator cap. Start the engine and warm
it up at 2,500 ~ 3,000 rpm for about 30 minutes.
8. When the air comes out from the radiator filler neck
and the EC level has gone down, replenish with the
EC. Repeat this procedure until the EC level does not
go down. Then stop the engine and install the radiator
cap. Let the engine cool down.9. After the engine has cooled, replenish with EC up to
the ªMAXº line of the reserve tank.
10. Start the engine. With the engine running at 3,000
rpm, make sure there is no running water sound from
the heater core (behind the center console).
11. If the running water sound is heard, repeat steps 8 to
10.

6. Disconnect the reserve tank hose(4) from radiator.

7. Lift up and remove the radiator assembly with hose,
taking care not to damage the radiator core with a fan
blade.
8. Remove rubber cushions on both sides at the bottom.
Inspection
Radiator Cap
Measure the valve opening pressure of the pressurizing
valve with a radiator filler cap tester.
Replace the cap if the valve opening pressure is outside
the standard range.
Valve opening pressure kPa (psi) 93.3 ~ 122.7
(13.5 ~17.8)
Cap tester: J±24460±01
Adapter: J±33984±A
Check the condition of the vacuum valve in the center of
the valve seat side of the cap. If considerable rust or dirt is
found, or if the valve seat cannot be moved by hand, clean
or replace the cap.
Valve opening vacuum kPa (psi) 0 ~ 6.9 (0 ~ 1.0)

Radiator Core
1. A bent fin may result in reduced ventilation and
overheating may occur. All bent fins must be
straightened. Pay close attention to the base of the fin
when it is being straightened.
2. Remove all dust, bugs and other foreign material.
Flushing the Radiator
Thoroughly wash the inside of the radiator and the engine
coolant passages with cold water and mild detergent.
Remove all signs of scale and rust.
Cooling System Leakage Check
Use a radiator cap tester to force air into the radiator
through the filler neck at the specified pressure of 150 kPa
(22 psi) with a cap tester:

Leakage from the radiator

Leakage from the coolant pump

Leakage from the water hoses

Check the rubber hoses for swelling.

Installation
1. Install rubber cushions on both sides of radiator
bottom.
2. Install radiator assembly with hose, taking care not to
damage the radiator core with a fan blade.
3. Connect reserve tank hose (4).
4. Install lower fan guide (3).
5. Connect radiator inlet hose and outlet hose to the
engine.
6. Connect oil cooler hose (1) to automatic
transmission.

7. Connect battery ground cable.
8. Pour engine coolant up to filler neck of radiator, and
up to MAX mark of reserve tank.

Engine Coolant Filling Up Procedure
1. Make sure that the engine is cool.
WARNING: WHEN THE COOLANT IS HEATED TO A
HIGH TEMPERATURE, BE SURE NOT TO LOOSEN
OR REMOVE THE RADIATOR CAP. OTHERWISE YOU
MIGHT GET SCALDED BY HOT VAPOR OR BOILING
WATER. TO OPEN THE RADIATOR CAP, PUT A
PIECE OF THICK CLOTH ON THE CAP AND LOOSEN
THE CAP SLOWLY TO REDUCE THE PRESSURE
WHEN THE COOLANT HAS BECOME COOLER.
2. Open radiator cap pour coolant up to filler neck.
3. Pour coolant into reservoir tank up to ªMAXº line.
4. Tighten radiator cap and start the engine. After idling
for 2 to 3 minutes, stop the engine and reopen radiator
cap. If the water level is lower, replenish.
5. After replenishing with coolant tighten radiator cap,
warm up the engine at about 2000 rpm. Set heater
adjustment to the highest temperature position, and
let the coolant circulate also into heater water system.
6. Check to see the thermometer, continuously idle for 5
minutes and stop the engine.
7. When the engine has been cooled, check filler neck
for water level and replenish if required. Should
extreme shortage of coolant is found, check the
coolant system and reservoir tank hose for leakage.
8. Pour coolant into the reservoir tank up to ªMAXº line.
