Prelude L4-1958cc DOHC (1989)
Catalytic Converter: Service Precautions
1. The catalytic converter routinely reaches operating temperatures of 650 °C (1200 °F). Do not park the vehicle over any object or material that
could ignite (i.e. dry leaves, cardboard, puddles of oil, or other combustibles). The catalytic converter will also stay hot for some time after the
engine has been shut off.
2. Parts of the exhaust gases (carbon monoxide) are toxic. Do not run the engine in confined areas or breathe concentrated exhaust gases. Breathing
exhaust gases may cause loss of consciousness or even death.
3. Repair any leaks in the exhaust system as soon as possible. Hot gases escaping from the leak can ignite flammable materials and may set the
vehicle on fire.
4. Be alert for fuel odors and excessive tailpipe emission output (black smoke etc...), these are problem indicators.
