ON-VEHICLE SERVICE

ENGINE COOLANT LEAK CHECK

M1141001000786

WARNING

When pressure testing the cooling system, slowly 
release cooling system pressure to avoid getting 
burned by hot coolant.

CAUTION

• Be sure to completely clean away any moisture from 

the places checked.

• When the tester is taken out, be careful not to spill any 

coolant.

• Be careful when installing and removing the tester and 

when testing not to deform the filler neck of the radia-
tor.

1. Check that the coolant level is up to the filler neck. Install a 

radiator tester and apply 160 kPa (23 psi) pressure, and 
then check for leakage from the radiator hose or 
connections.

2. If there is leakage, repair or replace the appropriate part.

RADIATOR CAP OPENING PRESSURE CHECK

M1141001301069

NOTE: Be sure that the cap is clean before testing. Rust or 
other foreign material on the cap seal will cause an improper 
reading.

1. Use a cap adapter to attach the cap to the tester.
2. Increase the pressure until the indicator of the gauge stops 

moving.

Minimum limit: 83 kPa (12 psi)
Standard value: 93 

− 123 kPa (14 − 18 psi)

3. Replace the radiator cap if the reading does not remain at or 

above the limit.

ENGINE COOLANT CHANGE

M1141001202883

Required Special Tool:

• MB991871: LLC Changer

WARNING

When removing the radiator cap, use care to avoid 
contact with hot coolant or steam. Place a shop towel 
over the cap and turn the cap counterclockwise a lit-
tle to let the pressure escape through the vinyl tube. 
After relieving the steam pressure, remove the cap by 
slowly turning it counterclockwise.

1. Drain the water from the radiator, heater core and engine 

after unplugging the radiator drain plug and removing the 
radiator cap.

2. Disconnect the cooling water line hose and drain the coolant 

in the water jacket. <2.4L ENGINE>

3. Disconnect the water feed hose B and drain the coolant in 

the water jacket. <3.0L ENGINE>
