Carefully clean the radiator cap and
the surrounding area before you
remove the cap.

to +113°F (+45°C).
• If the ambient temperature exceeds
0000079en
+113°F (+45°C) the engine may
overheat and cause the engine oil to
break down.

+5°F (-15°C) the engine will be hard to
start and the engine oil may not flow
