ENGINE COOLANT
InspectionINFOID:0000000001325845
LEVEL CHECK
 Check if the reservoir tank engine coolant level is within the “MIN”
to “MAX” when the engine is cool.
 Adjust the engine coolant level as necessary.
LEAK CHECK
 To check for leaks, apply pressure to the cooling system with the
radiator cap tester (commercial service tool) (A) and radiator cap
tester adapter (commercial service tool) (B).
WARNING:
Do not remove radiator cap when engine is hot. Serious burns
could occur from high-pressure engine coolant escaping from
radiator.
CAUTION:
Higher test pressure than speci fied may cause radiator damage.
NOTE:
In a case that engine coolant decreases, replenish radiator with engine coolant.
 If anything is found, repair or replace damaged parts.
Changing Engine CoolantINFOID:0000000001325846
WARNING:
 To avoid being scalded, do not change en gine coolant when the engine is hot.
 Wrap a thick cloth around radiator cap and carefully remove radiator cap. First, turn radiator cap a
quarter of a turn to release built-up pressu re. Then turn radiator cap all the way.
DRAINING ENGINE COOLANT
1. Remove front engine undercover with power tool.
2. Open radiator drain plug at the bottom of radiator, and then
remove radiator cap.
When draining all of engine cool ant in the system, open water drai n plugs on cylinder block. Refer
to EM-123, "
Disassembly and Assembly".
