ENGINE COOLANT
Inspection INFOID:0000000004305234
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 Coolant INFOID:0000000004673021
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-200 .
CAUTION:
• Perform this step when engine is cold.
• Do not spill engine coolant on drive belt.
2. Remove reservoir tank as necessary, and drain engi ne coolant and clean reservoir tank before installing.
Refer to CO-38, " Component " .
3. Check drained engine coolant for contaminants such as rust, corrosion or discoloration. If contaminated, flush the engine cooling system. SMA412B

Do not remove radiator cap when the engine is
hot. Serious burns could occur from high-pressure
engine coolant escaping from radiator. Wrap a thick cl oth around the cap. Slowly turn it a quarter of a
turn to release built-up pressure. Carefully remove radiator cap by turning it all the way.
