Periodic Maintenance Procedures
Radiator Hose and Connection Inspection
The high pressure inside the radiator hose can cause
coolant to leak [A] or the hose to burst if the line is not
properly maintained. Visually inspect the hoses for signs
of deterioration. Squeeze the hoses. A hose should not
be hard and brittle, nor should it be soft or swollen.
Replace the hose if any fraying, cracks [B] or bulges [C]
Check that the hoses are securely connected and clamps
are tightened correctly.

To avoid burns, do not remove the radiator cap or
try to change the coolant when the engine is still

Coolant on tires will make them slippery, and can
cause an accident and injury.
Since coolant is harmful to the human body, do not
use for drinking.
Place a container under the radiator drain bolt [A], then
remove the drain bolt (front view).
Remove the fuel tank (see Fuel System (DFI) chapter).
Remove the radiator cap [A] in two steps. First turn the
cap counterclockwise to the first stop. Then push and turn
it further in the same direction and remove the cap.
The coolant will drain from the radiator and engine.
Remove the water pump drain bolt [A]. The remaining
coolant will drain from the water pump [B].
Place a conduit under the drain hole of the pump cover.
The conduit leads to a container.
