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.
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

3. Replace the radiator cap if the reading does not remain at or above the limit.
ENGINE COOLANT REPLACEMENT 1. Drain the water from the radiator, heater core and engine after unplugging the
radiator drain plug and removing the radiator cap.
2. Drain the water in the water jacket by unplugging the drain plug of the cylinder
block. For the right bank side on AWD vehicles, drain the engine coolant from
the water feed tube assembly of the transfer box.
3. Remove the radiator condenser tank assembly and drain the coolant.
4. Drain the coolant then clean the path of the coolant by injecting water into the
radiator from the radiator cap area.
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 little to let the pressure escape
through the vinyl tube. After relieving the steam
pressure, remove the cap by slowly turning it
counterclockwise.

7. Assemble the radiator condenser tank assembly.
8. By referring to the section on coolant, select an appropriate concentration for
safe operating temperature within the range of 30 to 60 %. Use MB991871 to
refill the coolant. A convenient mixture is a 50 % water and 50 % antifreeze
solution [freezing point: -31°C (-32.8 °F)].
