LEVEL CHECK
●
Check if the reservoir tank engine coolant level is within the
“MIN” to “MAX” range 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
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.
Changing Engine Coolant

of a turn to release built-up pressure. Then turn radiator cap all the way.
CAUTION:
Be careful not to allow engine coolant to contact drive belts.
DRAINING ENGINE COOLANT
