How much does it cost to replace a camshaft on a 2018 Chevy Malibu?

In the United States, replacing a camshaft on a 2018 Chevy Malibu generally runs about $2,000 to $4,000, depending on engine type, parts selected, and labor rates.

Prices vary widely based on the specific Malibu engine (for example, the 1.5L turbo versus the 2.0L turbo), the extent of any damage to the valve train, whether a timing chain kit or timing components must be replaced, and local labor costs. Dealerships typically price higher than independent repair shops, and choosing OEM parts can add to the bill. Getting multiple, written estimates is the best way to gauge the actual cost for your situation.

What influences the price

The following factors commonly shape the final bill for a camshaft replacement on a 2018 Malibu.

• Engine variant and configuration (1.5L turbo vs 2.0L turbo) and whether the camshaft is replaced as part of a timing chain kit or as a standalone part.


• Extent of damage to the valve train, cylinder head, or related components, which may require additional repairs beyond the camshaft.


• Labor rate and shop type (dealership, independent shop, or franchise). Regional cost differences can be significant.


• Parts quality and warranty options (OEM/GM parts vs aftermarket). Higher-grade parts and longer warranties raise the price but may improve reliability.


• Additional services performed at the same time (oil change, timing cover reseal, water pump, gasket sets, coolant, or fluids).


• Whether the vehicle is still under warranty or covered by an extended service plan that could offset some costs.

Understanding these factors helps you compare quotes from different shops and anticipate where costs may shift during the repair process.

Estimated cost ranges by engine configuration

The following ranges reflect typical U.S. market pricing as of recent years and can vary by region and shop. They give a sense of what to expect for common Malibu configurations.

• 2018 Malibu with the 1.5L turbo engine: roughly $1,800 to $3,000 for parts and labor when camshaft replacement is straightforward and no major valve-train damage is present.


• 2018 Malibu with the 2.0L turbo engine: roughly $2,000 to $4,000, with higher potential if timing components or additional valve-train repairs are required.

In cases where extensive damage is found or multiple components (timing chain kit, guides, tensioners, seals) must be replaced, the total can drift toward the upper end or beyond. Always seek a detailed written estimate that itemizes parts, labor hours, and any ancillary work.

What’s included in the bill

Most camshaft replacement jobs in modern GM engines bundle several cost elements. A typical quote will break down these components, though exact line items vary by shop.

• Labor: hours at the shop’s hourly rate for disassembly, camshaft replacement, timing process, reassembly, and test drive.


• Camshaft kit or individual camshaft assembly, and any timing chain kit if required (chains, guides, tensioners).


• Related gaskets, seals, and possibly a new valve cover gasket or front cover seals.


• Fluids and consumables (engine oil, coolant, sealant, cleaners).


• Optional add-ons such as water pump, oil pump, or head gasket work if damage is discovered.


• Shop supplies and taxes (where applicable) and any diagnostic fees if a scope check is performed.

Because these jobs involve significant disassembly and precise timing alignment, the bill often reflects both substantial labor and high-quality parts. A written estimate that lists all parts and labor helps you compare offers more effectively.

How to plan and get quotes

To secure a fair price and avoid surprises, follow a structured approach to quotes.

• Request multiple, written estimates from independent shops and dealerships to compare labor hours, parts, and total cost.


• Ask whether the camshaft kit includes timing components and whether OEM GM parts are used by the shop.


• Inquire about the warranty on parts and labor and what conditions apply (e.g., coverage for subsequent valve-train issues).


• Confirm the anticipated timeline and whether a loaner vehicle or alternative transportation is available during repair.

Preparation helps you understand the true cost drivers and select a solution that balances reliability with value.

Replacing a camshaft on a 2018 Chevy Malibu is a major repair with a typical price range in the United States of roughly $2,000 to $4,000, depending on engine type, extent of damage, and parts choices. Engine variant, the need for timing components, regional labor rates, and the inclusion of additional repairs all influence the final bill. Prospective buyers should obtain several written estimates, review what’s included, and consider warranty terms before authorizing the work. If you’re facing this repair, a careful comparison of quotes will help you arrive at an solid, transparent decision.

How expensive is it to fix a camshaft?

The average cost to replace a camshaft is $1,000 to $2,500, including parts and labor. However, the total cost can range significantly from a few hundred dollars for a minor repair to thousands for a full engine replacement or complex jobs, depending on the vehicle, labor rates, and the extent of damage.
 
Cost breakdown

• Parts: A new camshaft itself can cost between $200 and $800, but the price increases for specialty or OEM parts. 
• Labor: Labor is often the most expensive part of the job, typically costing between $800 and $1,500 or more, depending on how complex the job is for your specific engine. 
• Associated parts: If the camshaft has failed, other components may need replacement, such as lifters, gaskets, timing components, and seals, which can add $200 to $500 or more to the total cost. 

Factors that influence cost

• Vehicle make and model: The cost varies widely based on the vehicle, with more complex or high-performance engines being more expensive to repair. 
• Extent of damage: If the camshaft failure has caused other internal engine damage, the total cost will be much higher and could potentially involve a full engine replacement. 
• Labor rates: The hourly rate of the mechanic or dealership can significantly impact the final price. 
• Warranty coverage: If your vehicle is under warranty, the cost of replacing a camshaft may be covered. 

What to do

• Get an accurate diagnosis and quote from a trusted mechanic to understand the full scope of the repair. 
• If the damage is severe, weigh the repair cost against the vehicle's trade-in value and the potential for future problems. 
• Consider the risk of further engine damage if you continue to drive with a failing camshaft. 

Is it worth replacing a camshaft?

Yes, replacing a camshaft is worth it if it is damaged or excessively worn, as this will restore engine performance, improve efficiency, and prevent more extensive engine damage. A damaged camshaft can cause symptoms like misfires, poor acceleration, and increased emissions, and ignoring it can lead to a catastrophic engine failure. The decision to replace depends on the severity of the wear and the cost versus the car's overall value and your plans for it. 
When it is worth replacing

• Signs of wear: The most common reason to replace a camshaft is physical wear on the lobes, which can be seen as a sharp edge or "dished" appearance. This is often accompanied by engine problems. 
• Preventing engine damage: A worn camshaft can cause cascading damage to other components like lifters and bearings. Replacing it is a preventative measure to avoid a more costly repair down the line. 
• Performance issues: If you're experiencing a noticeable loss of power, poor acceleration, or rough idling, a worn camshaft is a likely culprit. 
• Improved fuel efficiency: A new camshaft can help restore your engine's efficiency, which can be a significant financial advantage over time. 
• Enhanced engine longevity: A properly functioning camshaft is crucial for long-term engine health. Replacing a worn one can extend the life of your engine. 

When it may not be worth it

• Minor wear: If the cam and its components show only minor wear, it may not be necessary to replace the camshaft, especially if you're focused on keeping costs low. 
• Cost-prohibitive: If the vehicle is old and has a low resale value, the high cost of a camshaft replacement may not be a worthwhile investment for the car's worth. A cost-benefit analysis should be performed. 
• Timing belt vs. camshaft: Some people confuse a camshaft with a timing belt, which does have a regular replacement interval (around 90,000-100,000 miles) and is often a preventative maintenance item. Replacing a camshaft is a repair for a specific failure, not a routine maintenance item. 

What to consider

• Professional diagnosis: Have a mechanic inspect the camshaft to confirm it is the source of the problem before proceeding with a replacement. 
• Related components: When replacing the camshaft, it is often recommended to replace related components at the same time, such as lifters or a timing belt, which can increase the total cost. 
• Resale value: If you plan to sell the car, a new camshaft can increase its value, making the repair more justifiable.
