< NOTE >
Use a 50:50 mix of Long Life Coolant (LLC) for engine coolant.
Use GM SPEC 6277M or equivalent.
Always use potable water when mixing the coolant.
Use same type of coolant with identical mixture ratio for the sub-tank.
Do not use a high LLC mixing rate unless absolutely necessary. Doing so could result in
overheating or malfunction.
Replace LLC every 1 year or 1,000 hours.
LLC is a toxic substance. Wear rubber gloves and other protective wear when handling.
If someone mistakenly ingests LLC, induce vomiting immediately and seek medical care.
If LLC gets on skin or clothing, wash with water immediately.
LLC is flammable. Store in a location where flame is prohibited and it cannot be accessed by

Do not add engine coolant past the FULL level line of the coolant sub-tank.
