■ If the coolant level drops within a short time of replenishing
Visually check the radiator, hoses, engine coolant reservoir cap, drain cock and water
pump.
If you cannot find a leak, have your Lexus dealer test the cap and check for leaks in the
cooling system.
WARNING
When the engine is hot, do not remove the engine coolant reservoir cap or intercooler
coolant reservoir cap (NX350 only).
The cooling system may be under pressure and may spray hot coolant if the cap is
removed, causing serious injuries, such as burns.
NOTICE
■ 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 cooling.
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.
Checking the radiator, condenser and intercooler radiator
*
Check the radiator, condenser and intercooler and clear away any foreign objects.
If any of the above parts are extremely dirty or you are not sure of their condition,
have your vehicle inspected by your Lexus dealer.
WARNING
■ When the engine is hot
Do not touch the radiator, condenser or intercooler as they may be hot and cause serious
injuries, such as burns.
■ When the electric cooling fan are operating
Do not touch the engine compartment. With the engine switch in ON, the electric
cooling fan may automatically start to run if the air conditioning is on or the coolant
temperature is high. Be sure the engine switch is OFF when working near the electric
cooling fan or radiator grille.
