2-24 PERIODIC MAINTENANCE
Water Hose Damage and Installation Condition
The high pressure inside of the water 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.
