Replacing a Chrysler 300 engine typically costs about $4,000 to $9,000 in the United States, depending on the engine type and whether you use a remanufactured, rebuilt, or new crate engine, plus labor. Higher-end variants can push past $10,000.
This article details the engine options for the Chrysler 300, the factors that influence price, and practical steps to get accurate quotes from repair shops.
Engine options for the Chrysler 300
The Chrysler 300 has used several engines across its generations. The most common current configurations you’ll encounter are the 3.6L Pentastar V6, the 5.7L Hemi V8, and the 6.4L Hemi in the SRT8 variant. Older pre-2010 models may have 2.7L or 3.5L V6 engines. Replacement costs vary by engine type, availability of remanufactured units, and the labor required.
3.6L Pentastar V6
The 3.6L Pentastar V6 is the modern workhorse for most mid- to late-model Chrysler 300s. Replacing this engine generally falls in the mid-range for installed cost, with remanufactured or rebuilt units typically in the $4,000 to $7,000 range, and crate engines with installation often edging toward $8,000 to $9,000 depending on supplier and parts kit.
5.7L Hemi V8
6.4L Hemi V8 (SRT8)
The 6.4L Hemi, used in the SRT8 variant, commands higher replacement costs due to its size and performance components. Typical installed costs for a remanufactured or rebuilt 6.4L engine run around $7,000 to $10,000; a crate engine with labor can reach $11,000 to $14,000 or more, depending on the source and included components.
Older engines (2.7L and 3.5L)
Earlier Chrysler 300 models used smaller V6s such as the 2.7L or 3.5L. Replacement costs for these engines are generally similar to other V6 replacements when using remanufactured units, commonly in the $4,000 to $7,000 range, with crate engines typically in the $6,000 to $10,000 range depending on availability and supplier.
Typical price ranges by engine type
Below is a quick reference for installed costs by engine type. These figures include parts and labor but can vary by region, shop, and whether you choose a remanufactured, rebuilt, or crate engine.
- 3.6L Pentastar V6: roughly $4,000 to $7,000 (reman/rebuild) or $8,000 to $9,000+ (crate engine with installation)
- 5.7L Hemi V8: roughly $5,000 to $8,000 (reman/rebuild) or $9,000 to $12,000+ (crate engine with installation)
- 6.4L Hemi V8 (SRT8): roughly $7,000 to $10,000 (reman/rebuild) or $11,000 to $14,000+ (crate engine with installation)
- Older 2.7L/3.5L: roughly $4,000 to $7,000 (reman/rebuild) or $6,000 to $10,000+ (crate engine with installation)
Prices vary widely based on supplier, whether the engine is used, rebuilt, or new, and the included ancillary parts. It’s common to see broader ranges in the real world due to local labor rates and core charges.
Factors that influence the total cost
Several variables drive the final price tag for an engine replacement. Here are the main ones to consider.
- Engine source: remanufactured vs rebuilt vs crate/new. Crate engines are typically more expensive but may come with longer warranties.
- Labor rates and hours: Shops in urban areas or with specialty capabilities may bill more per hour; total labor can vary widely.
- Region and taxes: Location affects both parts pricing and labor availability.
- Additional parts and services: Radiator, water pump, timing components, belts, hoses, seals, and ECU programming can add to the bill.
- Core charges and disposal fees: Remanufactured engines often involve a core deposit that is refunded upon return of the old engine core.
- Warranty terms: Longer or more comprehensive warranties can raise upfront costs but may save money on future repairs.
Understanding these factors helps you compare apples-to-apples quotes and avoid surprise charges.
How to get an accurate quote
To secure a precise estimate, follow these practical steps when contacting shops.
- Identify your exact engine type and model year, and confirm with the VIN if possible.
- Decide on the engine source (remanufactured, rebuilt, or crate) and request quotes for each option.
- Ask for a detailed, itemized quote that includes engine price, core charge, labor hours, labor rate, and any additional parts.
- Inquire about ECU programming, timing adjustments, and any required re-flashing for compatibility with the new engine.
- Get quotes from multiple shops and ask about warranty terms and what they cover (labor, parts, or both).
Compare not only price but also the scope of work and warranty when choosing a service provider.
Cost-saving tips and common pitfalls
These tips help you balance cost with reliability and avoid common pitfalls.
- Consider reputable remanufactured engines with solid warranties as a cost-effective balance of reliability and price.
- Obtain at least three written estimates and ensure they specify parts, labor, and warranty details.
- Plan for ancillary repairs that may be needed now or soon (cooling system, timing gear, water pump) to avoid paying for multiple labor events.
- Be cautious of unusually low quotes, which can indicate incomplete work, hidden fees, or questionable parts.
Approach each quote as a bundle: engine, installation, and all ancillary services with a clear warranty.
Summary
The cost to replace a Chrysler 300 engine depends largely on the engine family, source of the replacement (remanufactured, rebuilt, or crate), and local labor rates. In general, expect installed costs in the $4,000 to $9,000 range for common configurations, with high-end variants like the 6.4L Hemi typically pushing into the $11,000 to $14,000 territory when using crate engines. Use multiple quotes, confirm scope and warranty, and consider whether phasing in related cooling and timing components may save future labor. If the numbers don’t pencil out, you may also weigh the option of replacement versus repairing the existing powertrain in consultation with a trusted technician.
What are the worst years for Chrysler 300?
The first year or two of any totally new design is always a risky period, and 2005 and 2006 Chrysler 300 models have by far the highest number of user complaints and reliability issues.

Is it cheaper to fix an engine or replace it?
It may be a cheaper option: A full engine rebuild costs about $2,500 to $4,000. Rebuilding may make sense if the damage is limited and the engine's core is still in good shape. But if the engine has widespread failure or high mileage, a replacement may offer more long-term reliability.
Is it worth fixing a car with a blown engine?
Financially it's probably worth fixing a blown engine as long as the parts are available from a breaker or dismantler, as a new engine will often be more expensive than the value of the car.
