Periodic Maintenance Procedures
Water Hoses and Connections Inspection
The high pressure inside the water hoses [A] can cause
coolant to leak [B] 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 [C] or bulges [D]
Check that the hoses are securely connected and clamps
are tightened correctly.

First, bring the piston to the top-dead-center of its com-
pression stroke to inspect the valve clearance (the posi-
tion at the end of the compression stroke), when the cam
lobe faces outside of the camshaft.
Place a wrench over the flywheel nut and turn it counter-
clockwise to align the TDC mark [A] with the center of the
groove [B] of the inspection hole.
