INFOID:0000000006827557

WARNING:

Be sure to perform when the engine is stopped.

1. Remove air duct and resonator assembly when inspecting drive belt.
2. Make sure that indicator (single line notch) of each auto tensioner is within the allowable working range

(between three line notches).

NOTE:

• Check the drive belt auto tensioner indication when the engine is cold.

• The indicator notch is located on the moving side of the drive belt auto tensioner.

ENGINE COOLANT
ENGINE COOLANT : System Inspection

INFOID:0000000006827558

WARNING:

• Never remove the radiator/reservoir cap when the engine is hot. Serious burns could occur from

high pressure fluid escaping from the radiator or reservoir.

• Wrap a thick cloth around the cap. Slowly push down and turn it a quarter turn to allow built-up pres-

sure to escape. Carefully remove the cap by pushing down and turning it all the way.

CHECKING COOLING SYSTEM HOSES

Check hoses for the following:

• Improper attachment

• Leaks

• Cracks

Drive belt

Power steering pump pulley

Generator pulley

Crankshaft pulley

A/C compressor

Idler pulley

• Damage

• Loose connections

• Chafing

• Deterioration

CHECKING RESERVOIR LEVEL

• Check if the engine coolant reservoir tank level is within MIN to

MAX level when the engine is cool.

• Adjust engine coolant level as necessary.

ENGINE COOLANT : Changing Engine Coolant

INFOID:0000000006827559

WARNING:

• To avoid being scalded, never change the coolant when the engine is hot.

• Wrap a thick cloth around the cap to carefully remove the cap. First, turn the cap a quarter of a turn

to release any built-up pressure, then push down and turn the cap all the way to remove it.

DRAINING ENGINE COOLANT

1. Turn ignition switch ON and set temperature control lever all the way to HOT position or the highest tem-

perature position. Wait 10 seconds and turn ignition switch OFF.

2. Remove the engine under cover using power tool.
3. Open the radiator drain plug at the bottom of the radiator, and

remove the reservoir cap. This is the only step required when

partially draining the cooling system (radiator only).

CAUTION:

• Perform this step when the engine is cold.

• Do not allow the coolant to contact the drive belts.

4. When draining all of the coolant in the system for engine

removal or repair, it is necessary to drain the cylinder block.

Remove the RH cylinder block drain plug to drain the right bank,

the oil cooler hose to drain the left bank as shown.

CAUTION:

Do not reuse copper sealing washers.

NOTE:

For Canada, the drain plug as shown is replaced by a block

heater.

5. Remove the reservoir tank to drain the engine coolant, then clean the reservoir tank before installing it.
6. Check the drained coolant for contaminants such as rust, corrosion or discoloration.

If the coolant is contaminated, flush the engine cooling system. Refer to

MA-34, "ENGINE COOLANT :

Changing Engine Coolant"

REFILLING ENGINE COOLANT

1. Close the radiator drain plug. Install the reservoir tank, cylinder

block drain plug, and the oil cooler hose if removed for a total

system drain or for engine removal or repair.

• The radiator must be completely empty of coolant and water.

• Apply sealant to the threads of the cylinder block drain plug.

Use Genuine High Performance Thread Sealant or equivalent.
