They almost always have a heat shield around them and an oxygen sensor somewhere before them. It is necessary for the catalytic converter to be before the muffler. The muffler is really the only thing that you can confuse for the catalytic converter on your Chevy Malibu. The catalytic converter may be bolted or welded on depending on the year and make of the vehicle. The catalytic converter for your Malibus cost will vary by model year and engine size.
But, as a rule catalytic converters are not cheap. They are one of the most stolen items on a vehicle there is. The failure mileage was 60, and the current mileage was 73, The contact stated that the popping sound in the steering wheel has occurred since he purchased the vehicle. The contact has a problem with his brakes. The calipers have been replaced three times since he purchased the vehicle.
The contact stated that they worked for a few days and began to squeak excessively again. Also, there was an egg smell in his car and began a few months after purchasing the vehicle. I have replaced spark plugs, coils, and the egr valve and the problem still occurs. Well, after further investigation online, I found other people to have the same problem and it turns out that it's with their cat converter.
Next is my head gasket, which looks like it has to be replaced. On I got an oil change and was told that there was oil in my coolant reservoir tank, which means I have an oil leak.
So now I have to take my car in and have the head gasket replaced which won't be cheap either. Read more First noticed problem when driving on freeway and attempting to make a lane change vehicle did not speed as usual and had to return to lane to avoid accident.
While driving vehicle from a complete stop, vehicle struggled from 0 to 25 mph. When going up bridge vehicle would not go faster than 20 mph. Vehicle does not have much power. Vehicle was taken to mechanic and replaced sensors but problem still occurs. After further investigation of problem mechanic realized that the problem is the catalytic converter.
The repairs have not been made. I entered the website to find out if there are any recalls on this vehicle for this problem recommendation from mechanic. The latest incident is the catalytic converter.
The car began to hesitate at mph and started losing power. I took it in and was told it was fine. However, having catalytic converter problems doesn't necessarily mean that the converter has to be replaced. You may be able to fix your catalytic converter without replacing it using one of the following methods. In your engine, fuel combines with oxygen in the air, set off by a spark or the heat of compression. Ideally, this chemical reaction would result in only motive energy, water vapor H2O , and carbon dioxide CO2.
However, In real-world driving conditions, the ideal is difficult to achieve, resulting in harmful emissions. The catalytic converter uses precious metals and high heat to oxidize and reduce harmful emissions, converting them into safer compounds like H2O, CO2, nitrogen N2. The "Italian Tune-Up" is a common fix for a range of automotive problems, including a clogged catalytic converter. Running a vehicle harder than usual for a few miles e.
For example, if you typically fill your vehicle with the cheapest low-octane fuel, try running your vehicle on a few tanks of high-octane fuel. Adding one gallon of lacquer thinner to ten gallons of gas at your next refuel may also be effective clearing out catalytic converter deposits.
You can try either of these methods in combination with the Italian Tune-Up method. You may need to fix other engine problems in order to solve your catalytic converter problem. A lazy oxygen sensor might falsely indicate a catalytic converter problem, yet not set a DTC for itself.
A technician can determine if the sensor is responding as it should. Other engine problems, such as fuel trim running too rich or too lean, oil or coolant burning, or engine misfire problems could all lead to catalytic converter contamination or premature failure. Depending on the extent of the damage already done, fixing engine problems might save the catalytic converter from a meltdown. Exhaust leaks are common and can skew oxygen sensor readings without setting other DTCs.
