When replacing an emission cleaning system, it is important to be able to assess the quality of a new part before installing it. A competent approach to selection will save time and money. Low-quality components can lead to serious problems in engine operation and expensive repairs.
Primary component inspection
Start with a visual inspection of the housing. A high-quality neutralizer has uniform welding without smudges and cracks. Carefully check all the seams – they should be neat and tight. Pay attention to the weight of the part – original components are usually heavier than fakes due to the higher content of precious metals in the filler.
The sound when lightly tapping on the housing should be dull, without rattling or metallic ringing. This indicates the correct density of the ceramic filler and the absence of damage to the internal structure.
By the way, if you plan to replace an old part, do not rush to throw it away. On the Avtokatalist platform, you can find out the current used cadillac converter prices and profitably sell the used component. This will help partially offset the cost of a new part.
Checking the documentation and markings
Before purchasing, it is important to carefully study the accompanying documentation. Each certified exhaust cleaner must have a full package of documents confirming its quality and compliance with standards.
Particular attention should be paid to the following aspects of quality control:
- Availability of a full set of accompanying documents, including a certificate of compliance with technical regulations and a warranty card from the manufacturer. All seals and signatures must be clear and distinguishable. The date of manufacture of the part and the validity period of the certificate must be current.
- The unique identification number on the body must match the number in the documentation and contain information about the manufacturer, date of manufacture and technical characteristics of the model. Marking is applied by engraving or stamping – stickers or paint are unacceptable.
- The geometric dimensions and shape of the flanges must exactly match the mounting locations on the exhaust manifold. Measure the diameter of the inlet and outlet openings, the center distances of the fasteners.
- The throughput and working volume must correspond to the engine power for optimal operation of the system.
After all checks have been completed, pay attention to the packaging of the part. High-quality factory packaging should be sealed, without damage or signs of opening.
Specifications and operation
A properly selected exhaust gas cleaner will ensure optimal engine operation and reduce fuel consumption. When installing, it is necessary to follow all the requirements of the instructions and the manufacturer’s recommendations. Incorrect installation can lead to damage to the part and disruption of the entire exhaust system.
Remember that saving on the quality of the exhaust gas cleaner can result in serious problems in engine operation and additional costs in the future. A thorough check before installation will help avoid these risks and ensure long-term flawless operation of your vehicle’s emission cleaning system.
