LEVEL CHECK

Check if the reservoir tank engine coolant level is within the
“MIN” to “MAX” 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 with
radiator cap tester (commercial service tool) and radiator cap
tester adapter (SST).
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.
