The method for cleaning a three-way catalytic converter is: 1. Add cleaning agent to the fuel tank; 2. Use a hanging bottle cleaning method, where the cleaning agent is drawn into the combustion chamber through the intake vacuum suction, and then burned, achieving the purpose of restoring the activity of the three-way catalytic converter through oxidation-reduction reactions inside it; 3. Disassemble and clean, removing the three-way catalytic converter and soaking it in oxalic acid and toilet cleaner, then rinsing it with clean water. The working principle of a three-way catalytic converter is: when high-temperature exhaust gas passes through the purification device, the purifying agent in the three-way catalytic converter enhances the activity of CO, HC, and NOx gases, promoting certain oxidation-reduction chemical reactions.

Will the paint repaired with touch-up paste peel off?

It will not peel off in the short term, but it's hard to judge beyond five years. It mainly depends on how the repair is done. If there is no sanding or any treatment—just a simple dab—it will peel off eventually. However, if the process includes sanding, spraying, and applying clear coat, it should last for five years without issues. Below are explanations on timely car washing after rain and scratch treatment: Timely car washing after rain: Rainwater contains many acidic substances and dust. After rain, the water stains on the car body gradually shrink, increasing the concentration of acidic substances in the rainwater. Combined with the dust in the rain, these stains can damage the car's paint over time if not rinsed off with clean water promptly. Scratch treatment: Minor scratches, whitened marks, or hairline scratches on the paint surface during vehicle use generally do not require touch-up paint. Light scratches can be treated with car wax, while slightly deeper ones may need polishing. If the scratch is severe enough to reveal the primer layer underneath, further action may be necessary.

What's the matter with the 'Service Brake Assist' warning on a Buick?

Reasons for the 'Service Brake Assist' warning on a Buick: Dirty sensor: It could be due to a dirty sensor, or the sensor wire being very thin, which may become loose when frequently driving on rough road conditions. Slow response during emergency braking: If the driver reacts too slowly or hesitantly during emergency braking, it prolongs the time for the braking system to reach maximum braking force, resulting in longer braking distances and increased driving hazards. The Brake Assist system can detect the driver's emergency braking intention and activate the ABS. By pre-detecting potential emergency situations, it provides pre-braking and, when necessary, offers greater assisted braking force to help reduce the braking distance.
