General Motors uses four different converter designs in conjunction with two types of catalysts.
The four converter designs are:
1.
Single bed monolith
2.
Dual bed monolith
3.
Single bed pellet
4.
Dual bed pellet
The two types of catalysts used are an Oxidation catalyst and a Three-Way (Oxidation/Reduction) catalyst. All dual bed converters, whether monolith or
pellet type, are three-way converters containing both oxidation and reduction catalysts.
NOTE: Use of leaded fuels, or fuel additives containing lead contaminates the catalyst, rendering the catalyst ineffective. Use only unleaded fuels on
catalytic converter equipped vehicles. A small diameter fuel tank filler is used on catalytic converter equipped vehicles to prevent the introduction of
leaded fuel from the larger diameter leaded fuel pump nozzles.
CAUTION: Prolonged operation with a misfiring or flooded engine may cause the converter to overheat. This could cause damage either to the catalyst
itself or the operating vehicle and possible personal injury. Also, when jacking or lifting vehicle from frame side rails, be certain lift pads do not contact
catalytic converter otherwise damage to converter may result.
