They had it 2 days. Yes, bolts in the exhaust system are notorious for getting stuck or rusted but every mechanic knows how to deal with them even if it means snapping, grinding, or torching them off.
As a 24yr BMW mechanic I had my fair share of nuts and bolts that would not come off. I got very good and creative in persuading most to come off. On occasion one would break off before I realized it was stuck. It all takes time, whether heating and soaking with lubricant or cutting, drilling and tapping. It takes a seasoned and experienced mechanic to resolve the problem without further damage.
My mechanic said the bolts are rusted on my catalytic converter and that they will need to drill them out. He said it may take several hours. Cutting or torching them is the usual method. Your mechanic is trying to take you for a ride. He wants you to replace it so be can put a aftermarket not approved non OEM new convertor. Any reputable shop will have an air powered cuttoff wheel or a torch set making removal fast, and I am talking under 5 minutes for ANY type clamp!
Shady practices are all over in the automotive world. Can having your serpentine belt switched and the air compressor switched on a Nissan Marano calls the Cadillac converter to go out. The mechanic is recommending a new catalytic converter because the car is idling too high and accelerates without your foot on the pedal?
The first line of the article says the cat converter removes carbon dioxide. Being told catalytic converters is expanding. Noticing a loud noise when driving.
I have a check engine light P on a Acadia. Need to fix this to get the emission test completed. What is the usual cause of this and can the average mechanic diagnose it and repair it? Or should I take it to the dealer? P essentially means your car is running rich as detected by the O2 sensor.
Likeliest causes are your sensor could be bad, you may have damaged wiring to the sensor, or you have a bad MAF or MAP sensor. You can try looking at those things yourself or take to a local mechanic avoid the dealership for something like this.
Exhaust came loose. My son welded it back. The O2 sensors are separate from the cat. I believe your car has 2 sensors but you can contact your local GMC dealership to confirm. Mechanic used diagnostic and got catalytic converter code. He reset code and told me to drive to see if comes on again. Just came on again. Is cat for sure the problem? It may not even be one as they rarely fail. What code did the computer throw when the tech scanned the car? This will tell which part of the exhaust system is affected.
I usually recommend the cheapest fix first where in this case would be to try using a good cleaner. I have a 97 Acura CL. I was told by a muffler shop that it would take an hour to an hour and a half to replace exhaust and catalytic converter.
It took 35 to 40 minutes. Does that seem enough time to replace items? Should be fine. Sounds like they ended up not having too much trouble with them. Hello my check engine light went on and I would get a stinky smell through the vent when driving the car sometimes. So I took it in and was told that 2 of my 4 catalytic converters were bad. He is quoting me over 5, Does that sound about right?
I have a QX56 Infiniti. I assume you went to a dealership? The components inside act as a catalyst to help convert these toxic substances to something less harmful. Hence the name: catalytic converter.
Because they contain several rare metals, including platinum, palladium, and rhodium. This is one of the reasons catalytic converters carry a high price tag. Platinum and rhodium pull oxygen off the nitrogen atoms, causing the harmless nitrogen to exit the exhaust. Then, platinum and palladium use the remaining oxygen molecules by combining them with carbon monoxide to create CO2. How does your engine optimize these reactions? One is located before the catalytic converter and one after.
Now that you have a better idea of what a catalytic converter is and how it works. A faulty catalytic converter will also affect the performance of your vehicle. It will cause your car to burn more fuel to attain the same performance, produce a reduction in engine power and cause overheating. Any significant overheating can damage your engine and the components surrounding it.
A catalytic converter is an essential part of your exhaust system. Its job is to reduce the toxic emissions and pollutants, produced by your engine, into less harmful gasses. In , over k vehicles failed their MOT test due to dangerously high emissions. Your catalytic converter is made of ceramic blocks with a porous structure.
By coating the pores with a selection of valuable metals: platinum, rhodium and palladium, they act as a filter to break down the toxic exhaust gases produced by burning petrol. The gasses your converter is designed to break down include hydrocarbons, carbon monoxide and nitrogen oxides. Essential among these factors is the cost involved. The cost of replacing a catalytic converter varies significantly depending on several factors.
For instance, the amount of work needed to replace the cat and the car model will influence the catalytic converter replacement cost. Some catalytic converters take several hours to replace, so it is advisable to inquire about the labor cost involved beforehand. Catalytic converters of newer models — those manufactured after are quite challenging and expensive to replace compared to those of older models.
These costs are not always fixed — they vary a lot, so it is advisable to get a quote first before allowing anyone to start working on the converter.
