WARNING
Removing the Cooling System Cap:
Removing the cooling system cap
while the engine is running or hot is
dangerous. This might lead to cooling
system and engine damage and could
result in serious injury from escaping
hot coolant or steam. Turn off the
engine and wait until it's cool. Even
then, be very careful when removing
the cap. Wrap a thick cloth around the
cap and slowly turn it
counterclockwise to the first stop.
Step back while the pressure escapes.
When you're sure all the pressure is
gone, press down on the cap ― still
using a cloth ― turn the cap, and
remove it.
1. Remove the cooling system cap.
2. Only when the engine is cool, loosen
the radiator drain plug and drain the
coolant into a suitable container.
Properly dispose of the used coolant.

4. Drain the system completely and
retighten the plug. Add as much
ethylene-glycol-based coolant mixture
and water as necessary to provide
freezing and corrosion protection.
5. In extremely cold climates, add the
mixture percentage recommended in
the coolant mixture percentage table.
6. Reinstall the cooling system cap.
7. Run the engine at idle for about 10
minutes, then turn it off. If the coolant
level warning light comes on during
this time, turn the engine off.
After turning off the engine, inspect the
drain plug and the water hoses for
leaks.
8. After the engine has cooled, remove
the cooling system cap and inspect the
coolant level. If it's low, repeat steps 5
to 7.
