Check the radiator, condenser and intercooler radiator and clear away any for-
eign objects.

■ When the engine is hot (RC350/RC300/RC200t)

radiator cap. (P. 612)
The cooling system may be under pressure and may spray hot coolant if the cap is
removed, causing serious injuries, such as burns.

The cooling system may be under pressure and may spray hot coolant if the cap is
removed, causing serious injuries, such as burns.
■ When adding coolant
Coolant is neither plain water nor straight antifreeze. The correct mixture of water and
antifreeze must be used to provide proper lubrication, corrosion protection and cool-
ing. Be sure to read the antifreeze or coolant label.
■ If you spill coolant
Be sure to wash it off with water to prevent it from damaging parts or paint.
