One to his workshop Nissan A mechanic who brought the pickup was completely confused when he realized what the “red light” seen on the underside of the vehicle was connected to.
Olay, Bratz Tire and Auto Shared by the service named. Service officials stated that the owner of the vehicle brought the pickup to the workshop after noticing a mysterious “red light” on the underside of the vehicle.
“I started looking around and… Oh! There you are! Yeah, I don’t think that’s an LED,” said the unnamed mechanic, who leaned over and noticed the exhaust system was very hot and glowing red.
In particular, the source of the problem seems to be the catalytic converter. Although this part is designed to withstand high temperatures while burning off harmful emissions before exhaust gases exit the pipe, it is not normal for it to glow this way.
According to the U.S. National Highway Traffic Safety Administration (NHTSA), such problems increase the risk of fire and explosion and should be addressed immediately as soon as the driver becomes aware of the problem.
So what is the reason for this situation? The most common cause is unburned fuel in the exhaust system. When the fuel that needs to be burned in the engine reaches the catalytic converter, it ignites there and causes temperatures to rise rapidly.
This situation; It can be caused by faulty spark plugs, failing ignition coils, faulty fuel injectors, or problems with oxygen sensors.
Fat burning also contributes to this problem. When piston rings or valve seals wear, oil can reach the catalytic converter, disrupting its operation and causing heat to build up, leading to internal blockages.
In some cases, the catalytic converter itself may be faulty or clogged; This is mostly seen in high mileage vehicles. When exhaust flow is restricted, heat increases rapidly and browning metal becomes the visible symptom of this restriction.
Repair costs can range from $1,500 to $3,000. However, replacing the catalytic converter without addressing the root causes, such as ignition or fuel supply problems, often leads to repeated failures. Therefore, it is important to evaluate the real cause of the problem with your mechanic before replacing the exhaust system.
