I had a catalytic converter installed in my vehicle in 2013, now I’m being told I need a new one. How long is it suppose to last?
When this happens it can become clogged or filter excess gases poorly, which will cause the vehicle to run very poorly as a result (think of a sink being backed up), not allowing it to flush out toxic gases which become backed up inside the vehicle’s exhaust system. If you not experiencing any drivability concerns, I would ask the person why they suggested having it replaced. If you would like to have the car checked for a second opinion, a certified technician from YourMechanic can come to your home or office to give the vehicle a complete inspection.

If you have downloaded Diagnostic Trouble Code P0306 that means that Cylinder No. 6 is misfiring but the causes of that misfiring can be VERY varied. Among the causes of cylinder misfiring are faulty spark plugs, low compression, damage or excessive wear of spark plug wires and/or coils, faulty fuel injector, clogged EGR valves or tubes, burned valves, improper ignition timing, vacuum leaks, leaking head gasket, faulty camshaft sensor, faulty crankshaft sensor, faulty mass air flow sensor, faulty oxygen sensor, faulty throttle position sensor, faulty catalytic converter, and others. If you want the cause pinpointed by a certified Mechanic, dispatched by YourMechanic right to your location, please request a misfiring diagnostic and the responding certified mechanic will get this diagnosed and resolved for you. If you have further questions or concerns as you decide what to do, do not hesitate to re-contact YourMechanic because we want you to make the most of your repair dollars and help you get the best possible results.
If no leak is present and yet you still have a leak once the engine runs and gets hot, that means that the leak is between two surfaces that are opening up under hot engine operation. But the same protocol applies. That is, at that point, inasmuch as the leak detection dye is still in the system, you should just let the engine cool completely and use your UV light source again to methodically check all of the obvious possible areas of the system that could leak.
I recommend having a certified mechanic, such as one from YourMechanic, perform an inspection to determine the source of the coolant leak and suggest any needed repairs.
