General
Caution! Removing the radiator cap while the engine is hot can allow the coolant to spray out, seriously scalding you. Always let the engine and radiator cool down before removing the radiator cap.
Notice: Using coolant with silicate corrosion inhibitors may cause premature wear of water pump seals or blockage of radiator passages. Using tap water may cause engine damage.
Add coolant at the reserve tank. Do not remove the radiator cap except to refill or drain the system.
Avoid spilling coolant on painted surfaces.
After servicing the system, check for leaks with a cooling system tester.
If any coolant gets in your eyes, rinse them with water and consult a physician immediately.
If any coolant is swallowed, induce vomiting, gargle and consult a physician immediately.
If any coolant gets on your skin or clothes, rinse thoroughly with plenty of water.
Refer to section 19 for fan motor switch and thermosensor information.
