4. Install the Tool by installing the radiator cap adapter onto the

radiator neck opening. Then attach the gauge body assembly

with the refill tube and the venturi assembly to the radiator cap

adapter.

5. Insert the refill hose into the coolant mixture container that is

placed at floor level. Make sure the ball valve is in the closed

position.

• Use recommended coolant or equivalent.

Refer to

MA-18, "FOR USA AND CANADA : Fluids and Lubri-

cants"

.

CAUTION:

Never use any cooling system additives such as radiator

sealer. Additives may clog the cooling system and cause

damage to the engine, transmission and/or cooling system.

6. Install an air hose to the venturi assembly, the air pressure must

be within specification.

CAUTION:

The compressed air supply must be equipped with an air dryer.

7. The vacuum gauge will begin to rise and there will be an audible hissing noise. During this process open

the ball valve on the refill hose slightly. Rising coolant will be visible in the refill hose. After the refill hose is

full of coolant, close the ball valve. This will purge air trapped in the refill hose.

8. Continue to draw the vacuum until the gauge reaches 28 inches

of vacuum. The gauge may not reach 28 inches in high altitude

locations. Refer to the following table for expected vacuum read-

ings.

9. When the vacuum gauge has reached the specified amount, disconnect the air hose and wait 20 seconds

to see if the system loses vacuum. If the vacuum level drops, perform necessary repairs to the system

and repeat steps 6 - 8 to bring the vacuum to the specified amount. Recheck for leaks.

10. Place the coolant container (with the refill hose inserted) at the same level as the top of the radiator. Then

open the ball valve on the refill hose so the coolant will be drawn up to fill the cooling system. The cooling

system is full when the vacuum gauge reads zero.

CAUTION:

Do not allow the coolant container to get too low when filling, to avoid air from being drawn into

the cooling system.

11. Remove the Tool from the radiator neck opening and install the radiator cap.
12. Remove the non-vented reservoir cap.
13. Fill the cooling system reservoir tank to the specified level. Run the engine to warm up the cooling system

and top up the system as necessary before installing the vented reservoir cap.

14. Install the engine under cover. Refer to

EXT-15, "Removal and Installation"

.

°

to 122

°

F) using the “COLD”

range on the A/T fluid level gauge as follows:

a. Park the vehicle on a level surface and set the parking brake.
b. Start the engine and move the shift selector lever through each

gear position. Shift the shift selector lever into the “P” position.

c. Check the A/T fluid level with the engine idling.
d. Remove the A/T fluid level gauge and wipe it clean with a lint-

free paper.

CAUTION:

When wiping the A/T fluid from the A/T fluid level gauge,

always use a lint-free paper, not a cloth.

e. Re-insert the A/T fluid level gauge into the A/T fluid charging

pipe until the cap contacts the top of the A/T fluid charging pipe

as shown.

CAUTION:

To check A/T fluid level, insert the A/T fluid level gauge until

the cap contacts the top of the A/T fluid charging pipe, with

the gauge reversed from the normal inserted position.

f.

Remove the A/T fluid level gauge and note the A/T fluid level. If

the A/T fluid level is at low side of range, add A/T fluid to the

transmission through the A/T fluid charging pipe.

CAUTION:

Do not overfill the transmission with A/T fluid.

g. Install the A/T fluid level gauge and the A/T fluid level gauge bolt.

2. Warm up the engine and transmission.
3. Check for any A/T fluid leaks.
4. Drive the vehicle to increase the A/T fluid temperature to 80
