Inspection
LEVEL CHECK
M/T Models without A/C and A/T Models
●Check if the reservoir tank engine coolant level is within “MIN” to “MAX” when engine is cool.
●adjust the engine coolant level as necessary.
SMA412B
M/T Models with A/C
●Check if the reservoir tank coolant level is within MIN to MAX when engine is cool.
●Adjust coolant if too much or too little.
Vehicle front
LEAK CHECK
M/T Model without A/C and A/T Models
●To check for leakage, apply pressure to the cooling system with a radiator cap tester (commercial service tool) and radiator cap tester adapter (SST).
Testing pressure : 157 kPa (1.57 bar, 1.6 kg/cm2, 23 psi)
WARNING:
Never remove the radiator cap when the engine is hot. Serious burns could occur from high pressure coolant escaping from the radiator.
CAUTION:
Higher pressure than specified may cause radiator damage.

ENGINE COOLANT
NOTE:
In a case that engine coolant decreases, replenish radiator with engine coolant.
●If anything is found, repair or replace damaged parts.
M/T Models with A/C
●To check for leakage, fit the adapter to the reservoir tank (1), and then connect it to the tester.
MBIB1362E
●Warm up the engine and turn it off.
●Apply pressure to the cooling system and stop pumping.
Testing pressure : 10 kpa
(0.1 bar, 0.10 kg/cm2, 1.5 psi)
●If the pressure drops, look for leakage.
●Unscrew slowly the adapter from the reservoir tank to reduce the pressure in cooling system, and install the reservoir tank cap.
WARNING:
Never remove the reservoir tank cap when the engine is

hot. Serious burns could occur from high pressure engine coolant escaping from the radiator.
CAUTION:
Higher pressure than specified may cause radiator damage.
Changing Engine coolant
WARNING:
●To avoid being scalded, never change the coolant when the engine is hot.
●Wrap a thick cloth around radiator cap and carefully remove the cap. First, turn the cap a quarter of a turn to release built-up pressure. Then turn the cap all the way.
DRAINING ENGINE COOLANT
M/T Models without A/C and A/T Models
1.Disconnect radiator lower hose and radiator cap.
CAUTION:
Make sure to drain when the engine coolant temperature is cold.
2.Remove reservoir tank and drain the engine coolant in the following procedures.
a.Move relay case in front of the battery.
b.Disconnect the reservoir tank from fan shroud to remove. With force applied in the left direction of vehicle, pull up reservoir tank.
3.Check drain coolant for contaminants such as rust, corrosion or discoloration.
If contaminated, flush engine cooling system.
