ENGINE COOLANTPFP:KQ100
InspectionEBS00KOG
LEVEL CHECK

Check if the reservoir tank engine coolant level is within “MIN” to
“MAX” range when engine is cool.

Adjust engine coolant level as necessary.
LEAK CHECK

To check for leakage, apply pressure to the cooling system with
a radiator cap tester (commercial service tool) and a radiator
cap tester adapter (special service tool).
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 specified 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 CoolantEBS00KOH
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. Remove RH and LH undercovers.
2. Open radiator drain plug at the bottom of radiator, and then
remove radiator cap.
When drain all of engine coolant in the system, open water drain plug on cylinder block. Refer to
EM-82, "
CYLINDER BLOCK" .
3. Remove reservoir tank and drain engine coolant.
