Fuel System Inspection
Inspect the complete fuel system for damage
or leaks.
Engine Cooling System Inspection
Inspect the hoses and have them replaced if
they are cracked, swollen or deteriorated. Inspect
all pipes, fittings and clamps; replace as needed.
Clean the outside of the radiator and air
conditioning condenser. To help ensure proper
operation, a pressure test of the cooling system
and pressure cap is recommended at least once
a year.
Brake System Inspection
Inspect the complete system. Inspect brake lines
and hoses for proper hook-up, binding, leaks,
cracks, chafing, etc. Inspect disc brake pads for
wear and rotors for surface condition. Also inspect
drum brake linings for wear and cracks. Inspect
other brake parts, including drums, wheel
cylinders, calipers, parking brake, etc. Check
parking brake adjustment. You may need to have
your brakes inspected more often if your driving
habits or conditions result in frequent braking.
