How Much Does A New 5.7 Hemi Engine Cost

The 5.7L Hemi engine, a modern iteration of Chrysler's legendary hemispherical combustion chamber design, has become a mainstay in the American automotive landscape. Found in everything from Ram trucks to Dodge Challengers, it's a powerful and relatively reliable workhorse. But what happens when it's time for a replacement? Understanding the cost of a new 5.7 Hemi is crucial for owners, mechanics, and enthusiasts alike.

Factors Influencing the Cost

Several factors determine the price of a new 5.7 Hemi engine. The most significant is whether you opt for a crate engine (a brand new, fully assembled engine directly from the manufacturer or a reputable supplier) or a remanufactured engine (an engine that has been rebuilt with new or refurbished parts). A crate engine will invariably be more expensive than a remanufactured unit, but offers the peace of mind that comes with a factory-fresh product.

Other contributing factors include:

• Source: Buying directly from Mopar (Chrysler's parts division) will typically be more expensive than purchasing from a third-party retailer, though Mopar often offers warranties and quality assurance.
• Condition: Even within the "crate engine" category, there can be variations. Some may be "long blocks" (assembled engine block, cylinder heads, and internal components) while others are "complete engines" (including accessories like intake manifolds, fuel injectors, and sometimes even alternators and power steering pumps). A complete engine will, naturally, cost more.
• Year and Application: The specific year and intended vehicle application of the engine can also influence the price. For example, a 5.7 Hemi designed for a Ram 1500 might have different components or tuning compared to one destined for a Dodge Charger, affecting its cost.
• Supplier Reputation: Purchasing from a reputable supplier is paramount. Fly-by-night operations might offer tempting prices, but the risk of receiving a faulty or misrepresented engine is significantly higher. Research thoroughly and read reviews before committing to a purchase.

Estimated Cost Breakdown

As of late 2023/early 2024, expect to pay the following (estimates, prices can fluctuate):

• Remanufactured 5.7 Hemi: $3,500 - $6,000 (plus core charge, if applicable). A core charge is a refundable deposit you pay until you return your old engine to the supplier.
• Crate 5.7 Hemi (Long Block): $5,000 - $8,000
• Crate 5.7 Hemi (Complete Engine): $7,000 - $11,000+

These figures are just for the engine itself. They do not include:

• Labor: Installation costs can vary wildly depending on the mechanic's hourly rate and the complexity of the job. Expect to pay anywhere from $1,000 to $3,000+ for installation.
• Fluids and Consumables: Oil, coolant, filters, and other fluids will add to the overall cost.
• Ancillary Parts: While a "complete" crate engine includes many accessories, you might still need to replace hoses, belts, or other components during the installation process.
• Tuning: Depending on the application, the new engine might require custom tuning to optimize performance and ensure proper operation with the vehicle's computer system.

Factors to Consider Before Replacing

Before committing to a new engine, consider whether a rebuild or repair might be a more cost-effective option. A skilled mechanic can diagnose the problem and determine the extent of the damage. If the issue is limited to specific components, a rebuild might be significantly cheaper than a full engine replacement. However, if the engine has suffered catastrophic damage (e.g., a spun bearing or cracked block), replacement is often the most practical solution.

Also, consider the long-term value of your vehicle. If your car is nearing the end of its lifespan, investing in a new engine might not be the wisest financial decision. Weigh the cost of the engine replacement against the vehicle's overall worth and potential resale value.

Maintenance and Longevity

Once you've invested in a new 5.7 Hemi, proper maintenance is crucial for ensuring its longevity. Regular oil changes with the correct viscosity and quality oil are essential. Pay attention to cooling system maintenance, ensuring the system is properly flushed and filled with the correct coolant. Avoid extreme driving conditions and excessive idling when possible. Following these simple steps can significantly extend the life of your 5.7 Hemi and prevent costly repairs down the road.

In conclusion, the cost of a new 5.7 Hemi engine is a significant investment. Careful research, a clear understanding of your needs, and a reputable mechanic are essential for making an informed decision.
