For 1990-2009 cars only

Notice: If there is any mis-positioning, incorrect installation, or failure of components in the brake system pipes, hoses, or wheel cylinders, check for brake damage. The exhaust system components must have adequate clearance from the floor pan to avoid overheating of the floor pan, damage to the passenger compartment carpets and damage to items in the luggage compartments.

When installing exhaust parts, make sure there is enough clearance between the hot exhaust parts and the pipes and hoses. The pipes and hoses could be damaged by the heat.

Inspect the following components for damage:

    • The complete exhaust system
    • Nearby body areas
    • The trunk
    • The taillight seals

Damage could include any of the following conditions:

    • Broken parts
    • Missing parts
    • Misaligned parts
    • Open seams
    • Holes
    • Loose connections
    • Other deterioration

These conditions could permit exhaust fumes to seep into the trunk or passenger compartment. Any damaged areas must be corrected immediately.
