Cooling System
When you decide it's safe to lift the hood, here's what
you'll see:
1. Coolant Recovery Tank
2. Radiator Pressure Cap
If the coolant inside the coolant recovery tank is boiling,
don't do anything else until it cools down.
3. Electric Engine Fan
The coolant level should be at or above FULL. If it isn't, you
may have a leak in the radiator hoses, heater hoses, radiator,
water pump or somewhere else in the cooling system.
