Toyota 4Runner Catalytic Converter

Known for its reliability and exceptional power, your Toyota 4Runner is a great SUV to take off-roading. Don't get slowed down in the slightest by running on an inefficient Toyota 4Runner catalytic converter. When problems come up, get the replacement parts you need at AutoZone.

It's possible for motor oil or antifreeze to mix with the chemical mechanisms in the converter and impair its function. This causes your catalytic converter for Toyota 4Runner to emit illegal levels of carbon emissions. This is bad for the atmosphere, and it's also bad for your entire exhaust system.

Your Toyota 4-Runner is tough and reliable, which is one of the main reasons there are so many of these SUVs still on the road today. If your 4-Runner fails an emissions test, that may mean it is time to look into replacing some parts of the exhaust system. One important component of the exhaust system that has been in use since the 1970s is the catalytic converter's part responsible for changing the harmful gases into a safer form of exhaust. While this piece lasts for as long as 10 years with good care, if your SUV is older than that and having trouble with the exhaust, it may be time for a catalytic converter replacement for Toyota 4-Runner from AutoZone.

Although catalytic converters last for up to a decade, there are times when premature replacement is warranted. The Check Engine light is but an early warning, and the technicians at AutoZone have a Fix Finder to decipher the code and pinpoint where the issue is. Other symptoms of a faulty converter include a sulfur-like smell, a drop in fuel efficiency, sluggish acceleration, and even difficulty or failure to start. If your exhaust sounds more like a sputtering mess than a healthy roar, there is a problem.

In addition to these symptoms, trouble or issues with other parts of your SUV may contribute to premature converter failure. Problems with the oxygen sensor, fuel injector, floats, check valves, and spark plugs may also lead to the catalytic converter failing. When it is time for a replacement, find the right catalytic converters for your Toyota 4-Runner from the selection at AutoZone.
