Removing the catalyst together with the exhaust system from under the car
If there is damage or dents on the catalyst housing, it must be replaced
It must be periodically checked that there is sufficient air gap between the heat shield and the catalytic converter.
The catalyst is a reliable and simple device that does not need any maintenance, but there are some facts that the owner should be aware of in order to maximize the life of the catalyst:
- do not use leaded gasoline in a car equipped with a catalyst, as lead will coat the precious metals in the catalyst lattice, reduce their conversion efficiency and ultimately disable the catalyst;
- always keep the ignition and fuel systems in perfect order;
- if misfiring is observed during engine operation, do not operate the vehicle until the malfunction is eliminated;
- do not start the engine by towing;
- do not turn off the ignition at high engine speeds;
- do not use the car if a trace of blue smoke is visible from the exhaust pipe;
- after stopping the engine, the exhaust system continues to emit a significant amount of heat for a long time, so you should avoid parking the car on the grass and dry leaves;
- remember that the catalyst is fragile, so avoid hitting when removing the catalyst or exhaust system;
- the catalyst used on a well-adjusted car should last from 100 to 150 thousand kilometers of the car.
