Buy Chevrolet Cruze Catalytic Converters

Chevrolet Cruze catalytic converters-also called cat converters, exhaust catalysts, or emission cleaners-scrub dirty exhaust using precious-metal coatings before gases leave the tailpipe. They sit after the turbo on every 2011-2019 Cruze engine and are covered by an 8-year/80,000-mile federal emissions warranty; a limited 2013-2014 recall fixed early internal-damage problems. When the converter clogs or cracks you may see code P0420, smell sulfur, or feel sluggish power. Replacement usually runs between $900-$1,800 parts + labor, though prices vary with direct-fit or universal styles. Federal law forbids removing or tampering with a converter, and fines can reach $2,500 per violation, while recent crackdowns and anti-theft shields are helping cut converter thefts nationwide. Proper maintenance-fixing misfires fast, using the right oil, and recycling the old unit-keeps both your Cruze and the planet breathing easier.

Inside the converter is a ceramic honeycomb that gives exhaust plenty of surface area while letting it flow freely. That honeycomb is coated with platinum, palladium, and rhodium that trigger chemical reactions turning carbon monoxide, hydrocarbons, and nitrogen oxides into harmless water vapor and nitrogen gas (see how the honeycomb helps).
Most Cruze units sit just after the turbocharger; the upstream oxygen sensor tells the engine computer how well the cat is working, and a second sensor downstream double-checks the cleanup. (CruzeTalk)

First-generation Cruze sedans (2011-2015) used 1.4-L turbo, 1.8-L gas, or 2.0-L diesel engines; the second generation (2016-2019) added a 1.6-L diesel and new 1.4-L turbo-gas design (model details).
A voluntary Emission Recall 16186 replaced cats on many 2013-2014 Cruze cars with the 1.8-L engine because internal damage raised tail-pipe pollution (NHTSA bulletin PDF).

Under the U.S. Clean Air Act, catalytic converters are classed as "specified major emission components," so they're protected for 8 years or 80,000 miles-even if the basic power-train warranty expires (EPA FAQ).
California and other CARB-state Cruzes must use converters that carry an Executive Order number proving they meet stricter standards; look for labels or links on compliant parts. (MagnaFlow)

• Check-engine light with code P0420 or P0430. (NHTSA)
• Rotten-egg or sulfur smell. (Reddit)
• Poor acceleration or stalling, often after misfires or coolant leaks melt the cat's coating. (CruzeTalk)
  Ignoring these cues can overheat the converter until the honeycomb breaks apart, blocking exhaust flow.

Misfiring spark plugs or coil packs let raw fuel overheat the converter. (Reddit)
Oil burning or coolant leaks coat the precious-metal surface so it can't react. (CruzeTalk)
Long idling with a rich fuel mix or using leaded/race fuel can also poison the unit. (EPA NEPIS)

Owners report shop quotes around $1,600 for a 2014 Cruze-about $1,500 parts and $100 labor on average (owner discussion).
DIYers who weld and reuse hardware can spend under $400 on a universal unit, but extra gaskets, sensors, and a new flex pipe may erase savings.

Removing or selling a cat converter that isn't EPA-approved can draw fines up to $2,500 per violation (EPA guidelines).
Some states also require etching a vehicle's VIN on the converter to help police track stolen parts. (AP News)

Converter thefts spiked when rhodium and platinum prices soared, but State Farm data show a 74 % drop in claims in early 2024 after tougher laws and police stings (State Farm report).
Enhanced scrap-dealer rules have slashed thefts in hotspots like Connecticut (CTInsider article).
Anti-theft shields and wire-cage clamps add a steel barrier that scares off quick cuts (shield test roundup).

A spent Cruze cat holds about 1-2 g rhodium and several grams of platinum group metals, making recycling worthwhile (metal breakdown).
Special refiners grind the ceramic core to recover those metals for new converters, electronics, and jewelry (recycling process).

• Fix misfires immediately to stop raw fuel from overheating the cat. (NHTSA)
• Use the oil grade GM specifies; excess oil burning shortens cat life. (CruzeTalk)
• Let the engine warm fully before hard driving so the converter reaches normal operating temp.
• If you smell sulfur, run an OBD scan-early action may save the cat.

1. Disconnect the battery to avoid sensor short circuits.
2. Unplug both O₂ sensors; label them so they don't swap sides.
3. Unbolt the heat shield and old converter (penetrating oil helps on rusty Cruze studs). (CruzeTalk)
4. Fit new gaskets, torque bolts to spec, and reset the engine computer so it can relearn clean readings.
   Always work on a cool exhaust and use jack stands for safety.

Q: Why does code P0420 keep coming back even after I clear it?
A: The computer saw low efficiency from the converter or a failing O₂ sensor; a clogged cat is the most common cause on Cruzes. (CruzeTalk)

Q: Is my 2015 Cruze included in the catalytic-converter recall?
A: No. Recall 16186 covered most 2013-2014 1.8-L cars; check the NHTSA site with your VIN. (NHTSA)

Q: How long should a converter last?
A: Around 10 years or 100,000 miles if the engine runs clean and coolant doesn't leak. (CruzeTalk)

Q: Can I drive with a bad cat?
A: You can, but the car may lose power and could overheat the converter enough to start a fire-replace it soon.

Q: What's inside a converter that thieves want?
A: Tiny amounts of precious metals, especially rhodium, platinum, and palladium, worth hundreds per ounce. (WIRED)

Q: Are aftermarket cats legal in all states?
A: They must meet EPA rules everywhere, and CARB-states require special labeling. (MagnaFlow)

Q: Why did my converter melt after a coolant leak?
A: Coolant hitting the honeycomb coats the metals and makes the cat overheat and break apart. (CruzeTalk)

Q: Does premium fuel make the converter last longer?
A: Not directly; what matters is fixing misfires and avoiding leaded or high-sulfur fuel.

Q: What are the fines for deleting a converter?
A: Up to $2,500 per car under federal law, plus local penalties. (EPA NEPIS)

Q: How do anti-theft shields work?
A: They cage the converter with steel plates or cables so saw blades can't reach it quickly. (Car and Driver)

Q: Can I recycle my old converter myself?
A: You need a licensed recycler; they crush and smelt the ceramic to safely recover metals. (hensel-recycling.com)

Q: Will a universal cat hurt performance?
A: Not if it's sized for the engine and welded correctly, but direct-fit units bolt on faster. (Walker Exhaust)

Q: Does a diesel Cruze use the same converter?
A: Diesel models add a diesel particulate filter (DPF) ahead of the cat and use slightly different converter formulas.

Q: What maintenance keeps the cat healthy?
A: Use fresh oil, change spark plugs on schedule, and address check-engine lights right away.

Q: How can I tell if my replacement cat is genuine?
A: Look for embossed part numbers and, in CARB states, the EO number etched on the shell. (MagnaFlow)
