ENGINE COOLANT
E2-5prose procedureCoolant Protection
CAUTION
The engine has aluminum parts that can be damaged by alcohol or methanol antifreeze. Do not use alcohol or methanol in the cooling system. Use only ethylene-glycol-based coolant.
Use only soft (demineralized) water in the coolant mixture. Water that contains minerals will cut down on the coolant's effectiveness.
Coolant Protection
- 1Measure the coolant temperature and specific gravity with a thermometer and a hydrometer.
- 2Determine the coolant protection by referring to the graph shown.
- 3If the coolant protection is not proper, add water or coolant as necessary.

REPLACEMENT
Draining
WARNING
Removing the radiator cap or the coolant filler cap while the engine is running, or when the engine and radiator are hot is dangerous. Scalding coolant and steam may shoot out and cause serious injury. It may also damage the engine and cooling system.
Turn off the engine and wait until it is cool. Even then, be very careful when removing the cap. Wrap a thick cloth around it 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 it, and remove it.
Draining
- 1Remove the coolant filler cap, radiator cap and loosen the radiator drain plug.
- 2Disconnect the oil cooler hoses.
- 3Drain the coolant into a container.
- 4Flush the cooling system with water until all traces of color are gone.
- 5Let the system drain completely.
- 6Tighten the drain plug and connect the oil cooler hoses.
