How much does it cost to replace a catalytic converter on an F350?

The cost to replace a catalytic converter on a Ford F350 can vary significantly, but on average, it typically ranges from $1,000 to $2,500. This wide range is due to several factors, including the specific make and model of the vehicle, the cost of the replacement part, and the labor required to complete the repair.

Factors Affecting the Cost

The cost of replacing a catalytic converter on an F350 can be influenced by several key factors:

• Part Cost: The catalytic converter itself is a relatively expensive component, often costing between $500 and $1,500 for an F350. The price can vary depending on the specific make, model, and year of the vehicle.


• Labor Cost: The labor required to replace a catalytic converter can be significant, as it involves removing the old part and installing the new one. This can add an additional $500 to $1,000 to the overall cost.


• Accessibility: The location of the catalytic converter on the F350 can also impact the cost. If the converter is difficult to access, it may require more labor time, increasing the overall repair cost.


• Emissions Testing: In some areas, emissions testing may be required after a catalytic converter replacement, which can add an additional $50 to $100 to the total cost.

It's important to note that the cost can also vary depending on the specific repair shop or mechanic performing the work, as well as the quality of the replacement part used.

Reasons for Catalytic Converter Replacement

There are several common reasons why a catalytic converter on an F350 may need to be replaced:

• Failure: Over time, the catalytic converter can become clogged or damaged, reducing its efficiency and causing the vehicle to fail emissions tests.


• Theft: Catalytic converters are a common target for theft due to the valuable metals they contain, such as platinum, palladium, and rhodium. If a converter is stolen, it will need to be replaced.


• Damage: Physical damage to the catalytic converter, such as from a collision or road debris, can also necessitate a replacement.


• Upgrades: Some F350 owners may choose to replace their catalytic converter with a high-performance or aftermarket model, which can also increase the overall cost.

Regardless of the reason, it's important to address any issues with the catalytic converter promptly to ensure the vehicle's emissions system is functioning properly and to avoid potential fines or other penalties.

Can I still drive with a bad catalytic converter?

You can technically drive with a bad catalytic converter, but it's not recommended, especially if it's clogged, as it can lead to engine damage, poor performance, and potential legal issues. If the converter is simply inefficient but not blocked, you may be able to drive for a while, but if it becomes clogged, it can cause severe issues like engine misfires or a total loss of power, as the exhaust cannot escape. A professional diagnosis is needed to determine the extent of the problem.

Risks of driving with a bad catalytic converter

• Engine damage: A clogged converter can cause extreme back pressure, which can damage engine components like crankshafts, rings, and bearings over time. 
• Poor performance: You may experience a significant loss of power, engine misfires, rough idling, and an inability to accelerate past a certain speed. 
• Legal issues: In many areas, it is illegal to drive with a faulty or missing catalytic converter, and you could be fined or fail an emissions test. 
• Increased emissions: A failing converter will not properly clean the exhaust, leading to increased pollution. 

What to do if you suspect a bad catalytic converter

• Avoid driving: If you suspect a clogged converter, it is best to avoid driving the car to prevent further damage. 
• Get a professional diagnosis: Have a mechanic diagnose the issue to determine if the converter is clogged or just inefficient. 
• Consider towing: If you have to move the vehicle, consider using a tow truck to take it to a repair shop.

Is it worth replacing a catalytic converter?

Yes, replacing a catalytic converter is often worth it to avoid legal penalties, significant engine damage, and poor performance. While the initial cost is high, driving without one is not recommended due to the risk of failing emissions tests, a loud engine, reduced fuel efficiency, and potential damage to other engine components. 
Reasons to replace your catalytic converter

• Avoid legal and inspection issues: Many states require a working catalytic converter to pass emissions and smog tests for vehicle registration. Driving without one is illegal in most places. 
• Prevent engine damage: A malfunctioning or clogged converter can cause the engine to work harder, leading to sluggishness, misfires, and other issues. Continued driving can lead to more extensive and costly engine damage or failure. 
• Improve vehicle performance: A new converter will restore engine performance, improve acceleration, and can prevent other problems like stalling. 
• Increase fuel efficiency: A clogged converter can decrease your gas mileage, so replacement can improve your fuel economy. 
• Reduce harmful emissions: The primary function of a catalytic converter is to reduce harmful pollutants from your vehicle's exhaust, which is beneficial for the environment. 

When to consider replacement

• Signs of a problem: Look for symptoms like reduced engine power, a sulfur or rotten egg smell from the exhaust, poor acceleration, or a loud rattling noise from the exhaust system. The "check engine" light is often a sign of a failing catalytic converter, but it could also be triggered by other engine issues, so a proper diagnosis is important. 
• Cost vs. long-term cost: Even though replacement is expensive, the cost of ignoring the problem can lead to even more expensive engine repairs down the line. 
• Repair vs. replacement: If the catalytic converter is damaged, get an estimate for both repair and replacement. Often, replacement is the better option if the repair cost is similar to a new part. 

Why are Ford catalytic converters so expensive?

Catalytic converters are expensive, because they contain precious metals such as platinum, palladium and rhodium. They're also rather small and are fitted on the car's exhaust, making them an easy target.

What is the life expectancy of a Ford catalytic converter?

10 years
Catalytic Converters should run for at least 10 years, but they don't need to be replaced once the 10 years are up. It needs to get changed once you begin to notice these issues pop up and if it's recommended by the service technicians.
