Various Makes and Models
Proper diagnostics are required before replacing a catalytic converter. Replacing the
catalytic converter without xing the cause of the failure may lead to another ruined
converter that may not be covered under manufacturer’s warranties.
A proper break-in period is required for a correct installation:
A replacement catalytic converter needs to undergo a proper “break-in” procedure to
ensure that it will con tinue to work the way it is supposed to and deliver the required
emissions reliability and long service life. If the converter is not warmed-up properly
(broken-in), the substrate inside could be adversely aected and eventually cause the
converter to fail down the road.
Here are suggested steps for a proper break-in or warm-up:
• Start engine but do not touch the accelerator pedal.
• Idle the engine and allow it to warm up slowly.
• After 5 minutes, increase the engine speed to 2500 RPM.
• Hold at 2500 RPM for 2 minutes.
• Allow engine to cool down.
• Road test vehicle to conrm correct installation.
Installation suggestions:
• Silicone-based products or Teon sealants should not be used on any part of the
exhaust system. They are not designed to operate at high exhaust temperatures
and will out gas, causing damage to O2 sensors.
• When a converter is replaced, the technician will need to perform a drive cycle in
order to correctly reset the ECM. Follow the manufacturer guidelines for the correct
drive cycle.
