## What is wrong

DETERIORATION OF THE REED VALVE SUBASSEMBLY MAY LEAD TO A MALFUNCTION WITHIN THE SECONDARY AIR SUPPLY PORTION OF THE EMISSION CONTROL SYSTEM. THE SCREWS WHICH ATTACH THE REEDS TO THE REED VALVE SUBASSEMBLY MAY RUST, AND IF THE RUSTING BECOMES SEVERE, THE SCREW HEADS WILL ERODE AND ALLOW THE REEDS TO SEPARATE FROM THE REED VALVE SUBASSEMBLY. CORROSION MAY ALSO OCCUR ON THE REED VALVE SUBASSEMBLY, DEFORMING THE REED SEATS AND PREVENTING THE REEDS FROM CLOSING PROPERLY. SEPARATION OF THE REEDS FROM THE REED VALVE SUBASSEMBLY OR IMPROPER CLOSING OF THE REEDS ALLOW HOT EXHAUST GASES TO FLOW BACKWARD INTO THE PLASTIC SECONDARY AIR FILTER CASE WHEN THE VEHICLE IS BEING DRIVEN. THESE HOT EXHAUST GASES MAY MELT THE SECONDARY PLASTIC AIR FILTER CASE.


## What can happen

THE MELTING PLASTIC AIR FILTER CASE MAY LEAD TO A FIREIN THE ENGINE COMPARTMENT.


## The remedy

REPLACE THE REED VALVE SUBASSEMBLY WITH ONE WHOSE METAL COMPONENTS ARE FABRICATED FROM CORROSION RESISTANT STAINLESS STEEL.
