ENGINE COOLANT
InspectionINFOID:0000000005398212
LEVEL CHECK
• Check if the reservoir tank engine coolant level is within the “MIN”
to “MAX” range when engine is cool.
• Adjust the engine coolant level as necessary.
CHECKING COOLING SYSTEM FOR LEAKS
To check for leaks, apply pressure to the cooling system using suit-
able tool and Tool.
WARNING:
Never remove the radiator cap wh en 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.
Changing Engine CoolantINFOID:0000000005398213
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.
CAUTION:
• Do not spill engine coolant on drive belt.
DRAINING ENGINE COOLANT
1. Open radiator drain plug (1) at the bottom of radiator, and then
remove radiator cap.
• Front
When draining all of engine coolant in the system, open
water drain plug on cylinder block. Refer to EM-196
.
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-40, "
Component".
3. Check drained engine coolant for contaminants such as rust, corrosion or discoloration. If contaminated, flush the engine cooling system.

ENGINE COOLANT
10. Place the coolant container (with the refill hose insert
ed) 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.
12. Fill the cooling system reservoir tank to the specified level and install the radiator cap. Run the engine to warm up the cooling system and t op up the system as necessary.
FLUSHING COOLING SYSTEM
1. Install reservoir tank if removed. Refer to CO-40, "Component".
2. Install radiator drain plug. •If water drain plug on cylinder block is removed, close and tighten it. Refer to EM-196, "
Disas-
sembly and Assembly".
CAUTION:
Be sure to clean radiator drain plug and install with new O-ring. Refer to CO-40, "
Component".
3. Fill radiator and reservoir tank with water and reinstall radiator cap.
4. Run engine and warm it up to normal operating temperature.
5. Rev engine two or three times under no-load.
6. Stop engine and wait until it cools down.
7. Drain water from the cooling system.
8. Repeat steps 1 through 7 until clear water begins to drain from radiator.

Checking Radiator CapINFOID:0000000005398216
• Check valve seat of radiator cap.
- Check if valve seat is swollen to the extent that the edge of the
plunger cannot be seen when watching it vertically from the top.
- Check if valve seat has no soil and damage.
• Pull negative-pressure valve to open it, and make sure that it is completely closed when released.
- Make sure that there is no dirt or damage on the valve seat of radi-
ator cap negative-pressure valve.
- Make sure that the valve operates properly in the opening and closing conditions.
• Check radiator cap relief pressure using suitable tool and Tool.
- When connecting the radiator cap to the tester, apply water or coolant to the cap seal surface.
- Replace the radiator cap if there is an abnormality in the negative- pressure valve, or if the open-valve pressure is outside of the standard values.
• Replace radiator cap if there it does not comply to specifications to the above three checks.
CAUTION:
When installing radiator cap, thor oughly wipe out the radiator filler neck to remove any waxy residue
or foreign material.
Checking RadiatorINFOID:0000000005398217
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.
