 Catalytic Converters do not fail on their own. The most typical scenario is that an
over-rich fuel mixture--caused by a defective fuel injection or carburetor setup--allows
un-burnt fuel to find its way into the converter. There, due to the heat generated in the
catalysation process, the fuel burns inside the converter. The substrate in the converter
melts, then breaks up, resulting in exhaust system clogging and rattles.Installing a new converter on a vehicle with fuel system problems will result in failure of
the new converter. This can happen in as little as 100 miles. Substrate meltdown is
not covered by the manufacturer’s warranty. Before installing this replacement
converter, be certain that fuel and ignition systems are functioning properly, that valve
clearances are correct, and that all other emission equipment is in place and operating
correctly. Note: International Auto Parts extends a 60-day return privilege. The remainder of the two-year warranty is handled by the manufacturer. It is extremely important that you
complete and mail the warranty card enclosed in the converter box. |
