Nissan Frontier Catalytic Converter
5 Tips to Keep the Nissan Frontier Catalytic Converter Healthy
The catalytic converter of the Nissan Frontier is designed to be maintenance-free, and once it breaks down, it will almost always require replacement. However, catalytic converters still need to be used and cared for properly to help prevent early onset of wear. Here are five simple tips on how to keep the Nissan Frontier catalytic converter:
- Warm up the converter every time you start the truck.
Warming up the catalytic converter will allow the catalyst and the matting inside the chamber to expand properly, minimizing wear and helping prevent malfunctions. Start the engine and allow it to idle for five minutes. Afterwards, step on the gas and run the engine at 2,500 rpm for two minutes.
- Avoid overheating the engine.
While warming up the converter helps keep it running in top condition, too much heat can be damaging. Aside from potentially damaging the engine and radiator, running the engine at higher-than-normal temperatures can also melt the catalyst material inside the converter. And once this happens, the melted catalyst will clog up the pipes and cause the engine to misfire. So if you notice the engine posting temperatures that are hotter than usual particularly when running on idle, let it cool down and have the engine and radiator checked by a mechanic.
- Do not use fuel additives.
There's a reason why car manufacturers do not endorse fuel additives; catalytic converters are designed specifically to process fuel, and including fuel additives into the mix might contaminate the catalyst material and reduce its effectiveness.
- Get the converter undergo a carbon cleaning treatment.
Many auto repair shops also now offer "carbon cleaning" service, wherein the converter is treated to dislodge carbon deposits that have built up inside it over time. Ideally, the converter should undergo this process once at least every two years or 30,000 miles.
- Keep silicone away from the exhaust pipes.
Silicone, which is found in automotive lubricants and sealants, burn when exposed to the hot gases running through the catalytic converter and exhaust pipes. This will result in a condition called "outgassing", wherein the burnt silicone causes the oxygen sensor to malfunction and the converter to overheat.
