6. Stop engine and wait until it cools down.
7. Drain water from the cooling system. Refer to CO-11, "
Changing Engine Coolant".
8. Repeat steps 1 through 7 until clear water begins to drain from radiator.
RADIATOR
RADIATOR : Checking RadiatorINFOID:0000000001730858
Check radiator for mud or clogging. If necessary, clean radiator as follows.
Be careful not to bend or damage radiator fins.
When radiator is cleaned without removal, remove all surrounding parts such as cooling fan, radiator shroud
and horns. Then tape harness and connectors to prevent water from entering.
1. Apply water by hose to the back side of the radiator core vertically downward.
2. Apply water again to all radiator core surface once per minute.
3. Stop washing if any stains no longer flow out from radiator.
4. Blow air into the back side of radiator core vertically downward.
Use compressed air lower than 490 kPa (4.9 bar, 5 kg/cm
2, 71 psi) and keep distance more than 30 cm
(11.8 in).
5. Blow air again into all the radiator core surfaces once per minute until no water sprays out.
FUEL LINES
FUEL LINES : InspectionINFOID:0000000001277610

WARNING:
Be sure to perform this step when the engine is stopped.
Make sure that the indicator (notch on fixed side) of drive belt auto-tensioner is within the possible use range
(A).
NOTE:
Check the drive belt auto-tensioner indication when the engine is cold.
When new drive belt is installed, the indicator (notch on fixed side) should be within the range (B).
Visually check entire drive belt for wear, damage or cracks.
If the indicator (notch on fixed side) is out of the possible use range or belt is damaged, replace drive belt.

To check for leaks, apply pressure to the cooling system using suit-
able tool.
WARNING:
Never remove the radiator cap when the engine is hot. Serious
burns could occur from high pressure coolant escaping from
the radiator.
CAUTION:
Higher pressure than specified may cause radiator damage.
ENGINE COOLANT : Changing Engine CoolantINFOID:0000000001730870
WARNING:
To avoid being scalded, do not change engine coolant when engine is hot.
Wrap a thick cloth around radiator cap and carefully remove the cap. First, turn the cap a quarter of a
turn to release built-up pressure. Then turn the cap all the way.
Be careful not to allow engine coolant to contact drive belt.
DRAINING ENGINE COOLANT
1. Open radiator drain plug (1) at the bottom of radiator, and then
remove radiator cap.
Front
When drain all of engine coolant in the system, open water
drain plug on cylinder block. Refer to EM-211, "
Compo-
nent".
CAUTION:
Perform this step when engine is cold.
Do not spill engine coolant on drive belt.
2. Remove reservoir tank as necessary, and drain engine coolant and clean reservoir tank before installing.
Refer to CO-35, "
Changing Engine Coolant".
3. Check drained engine coolant for contaminants such as rust, corrosion or discoloration.
If contaminated, flush the engine cooling system. Refer to CO-35, "
Changing Engine Coolant".
REFILLING ENGINE COOLANT
1. Install reservoir tank if removed.
2. Install radiator drain plug.
If water drain plug on cylinder block is removed, install and tighten it. Refer to EM-211, "
Compo-
nent".
CAUTION:
Be sure to clean radiator drain plug and install with new O-ring. Refer to CO-40, "
Component".
3. Make sure that each hose clamp has been firmly tightened.
4. Remove air duct assembly. Refer to EM-154, "
Component".
