3. Inspect the cooling system for leaks.
For vehicles used in temperatures below -31°F (-35°C), change the coolant
from the standard 50:50 antifreeze:water mix to one with added antifreeze.
Consult a dealer for more information.
Adding Coolant
n
1. Make sure the engine and radiator are cool.
2. Turn the radiator cap 1/8 turn counterclockwise and relieve any
pressure in the coolant system.
3. Push down and turn the radiator cap counterclockwise to remove it.
4. The coolant level should be up to the base of the filler neck. Add coolant
if it is low.
5. Put the radiator cap back on, and tighten it fully.
Removing the radiator cap while the engine is hot can cause the coolant to
spray out, seriously scalding you.
Always let the engine and radiator cool down before removing the radiator
cap.
Pour the fluid slowly and carefully so you do not spill any. Clean up any
spills immediately; they can damage components in the engine
compartment.

face shield, or have a skilled technician do it.
