In case it is heavily damaged and has to be replaced, contact specialized companies to get a payback for your old converters unlimited. Common catalyst evaluation is as follows:
- Fixing the cost of the converters unlimited is determined by the marking on the housing.
- Establishing value of precious materials.
- Acceptance of all kinds and types of converters unlimited. The cost also depends on the condition and integrity.
Damaged catalyst with ceramic part of the monolith should not be washed with any chemical solutions. It has to be clean without natural moisture, asbestos. Ceramics in metal housings of aconverters unlimited has to be also clean and in full size.
The high cost of catalysts is due to the use of platinum, rhodium or palladium salts. Specialized companies purchase broken, defective, renewed and destroyed converters unlimited of all types, and also accept them for useful components with an aim to subsequent manufacture of new catalysts
These are just a few common signs to understand if the converters unlimited is damaged. If you notice at least one of them or it seems that something is wrong with the catalyst, try to find out the reason with the help of several tests. The driver can diagnose the catalyst malfunction independently, if he has the proper knowledge and necessary equipment. There are 3 main ways to test the catalyst:
1. VISUAL INSPECTION. Presence of problems in the converters unlimited can be determined “by eye”. If it is deformed, there is a good chance that honeycombs of the converters unlimited are damaged. At the same time, it will not be possible to inspect the device from the outside for clogging with dirt and combustion products. That is why, it will be necessary to remove the catalyst. After removing the converters unlimited, it is necessary to inspect it for the presence of gaps. Clogged catalyst can be cleaned or replaced with a new one.
2. COUNTER PRESSURE CHECK. The most common method for checking a catalyst that does not require dismantling. Essence of a back pressure test is that the exhaust pressure is measured, which is then compared with ideal indicators. To diagnose it, you will need a manometer and adapter to connect it. It is better to lift the car or drive it into a pit. Next, you need to remove the first oxygen sensor, and connect a pressure gauge in its place.
3. DIAGNOSTICS BY MOTOR TESTER The motor tester is a set of equipment that allows you to determine the state of many parameters. With this method of verification, a diagnostic device is installed instead of the spark plug, after which the engine starts and waveforms are taken. On their basis, experts make conclusions about the state of a catalyst. By eliminating problems with the converters unlimited in time, you can avoid costly engine repairs and significantly reduce fuel consumption.
