Cap adapter

Adapter

AA00

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

｠

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 radiator.

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 PRESSURE CHECK

Cap adapter

AA00

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.

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.

coolant.

4.

Drain the coolant then clean the path of the coolant by injecting
water into the radiator from the radiator cap area.

5.

Install the water feed hose B.

6.

Securely tighten the radiator drain plug.

7.

｠

Do not use alcohol or methanol anti-freeze or any engine
coolants mixed with alcohol or methanol anti-freeze. The
use of an improper anti-freeze can cause corrosion of the
aluminum components.

｠

If the coolant contact the PremAir® direct ozone
reduction (DOR) radiator, wash it with water at once.
Vehicles for California emission regulation

8.

By referring to the section on coolant, select an appropriate
concentration for safe operating temperature within the range
of 30 to 60 %. Use special tool MB991871 to refill the coolant.
A convenient mixture is a 50 % water and 50 % antifreeze
solution [freezing point: -31°C (-24 °F)].

Recommended antifreeze: Long Life Antifreeze
Coolant or an equivalent
Quantity:

9.5 dm3(10.0 quarts)
10.0 dm3(10.6 quarts) <Vehicles with Towing
Package or DOR radiator>

9.

Reinstall the radiator cap.

10.

Start the engine and let it warm up until the thermostat opens.

11.

After repeatedly revving the engine up to 3,000 r/min several
times, stop the engine.

12.

Remove the radiator cap after the engine has cooled, and
pour in coolant up to the brim. Reinstall the cap.

Do not overfill the radiator condenser tank assembly.

13.

Add coolant to the radiator condenser tank assembly
between the "FULL" and "LOW" mark if necessary.
