Acura 2009 RDX - Manual (Page 345)

The coolant level should be up to
the base of the filler neck. Add
coolant if it is low.
Do not add any rust inhibitors or
other additives to your vehicle’s
cooling system. They may not be
compatible with the coolant or
engine components.
Pour coolant into the reserve tank.
Fill it halfway between the MAX
and MIN marks. Put the cap back
on the reserve tank.
Make sure the engine and radiator
are cool.
Relieve any pressure in the cooling
system by turning the radiator cap
counterclockwise, without
pressing down.
Remove the radiator cap by
pushing down and turning
counterclockwise.
Put the radiator cap back on, and
tighten it fully.
Pour the coolant slowly and
carefully so you do not spill any.
Clean up any spills immediately; it
could damage components in the
engine compartment.
