How Much Does It Cost To Replace a 5.7 Hemi Engine?

The Hemi engine is a patent of Chrysler. It sports hemispherical combustion chambers. It is not the first one to have this shape, but it has significantly enhanced the advantages that come with this shape.

Hemi offers a higher compression ratio that leads to more power compared to flat piston engines. Having been around in Chrysler vehicles since 1964, Hemi has seen great improvements. If your Hemi engine is not in good condition, how much will you spend to replace it?

How Much Does It Cost To Replace a 5.7 Hemi Engine?

How Much Does It Cost To Replace a 5.7 Hemi Engine?

It will cost you between $5,600 and $13,000 to replace a 5.7 Hemi engine. If you go for remanufactured Hemi engines, it will cost you between $2,900 and $4,000 to purchase before you have a professional install it. The installation cost will depend on whether you do it or you have a professional do it.

If you go for a new Hemi engine, it will cost you about $8,500. Once you add the installation cost for the new engine, it will add up to about $10,000 or more.

Remanufactured engines are ready to run. However, used engines, which might cost as less as $1,000 might need more in terms of labor and modifications. In the long run, you might end up spending the same amount of money on a used engine as you do on a remanufactured engine.

The 5.7 Hemi engine is relatively heavy and also costly to produce. This makes the engine more expensive than other engines on the market. Again, note that the engine might reduce the mpg of your car, thanks to your truck.

Today, the engine is available in Dodge Charger, Dodge Challenger, and the Chrysler 300c. It is also available in Ram trucks. Truck owners love the engine, thanks to its power, strength, and great reliability.

New Engine vs Remanufactured Engines vs Used Engines: Which is more Affordable?

Used engines are the most affordable, but are they worth the hassle you go through to get them running?

You can buy used engines from a junkyard or any other used parts supplier. The engines, in most cases, come as are and where they are. The junkyard or any other seller might offer a few months warranty on the used engine, but that doesn’t cover the work a mechanic does on the old engine.

There is a chance that the used engine might fail to run after installation. If that happens, it takes the mechanic more time to fix and install the engine. In short, you will spend more money to fix and install the engine to ensure it is running efficiently.

A rebuilt engine takes the doubt that the engine may not run away. These engines have been refurbished back to the manufacturer’s specifications. Although the engine is not new, the remanufacturer replaces all worn parts to give the engine a more efficient performance and lengthen its productive life.

Rebuilt engines come with a more generous warranty, and you are sure they will run after installation. This means you do not spend so much on fixing and installation. However, you will pay more for a rebuilt engine.

While a used engine from a junkyard will cost about $1,000, a remanufactured Hemi engine will cost as much as $4,000. Some manufacturers, however, sell them for as low as $2,500.

Installing a rebuilt 5.7 Hemi engine saves you money and gives you a long service compared to someone who goes for a new engine. A new engine costs almost twice what the rebuilt engine costs. However, you have the confidence that the engine is efficient, in perfect condition, and will serve you for long.

What are the Labor Costs for Professional Engine Fixing and Installation?

You will be pay between $90 and $150 per hour for engine fixing and installation. In most cases, the mechanic takes between 10 and 12 hours to fix and install an engine. If the mechanic is fast and has a lot of help, they will do it in 8 hours.

If the engine requires complex fixing, say a junk engine that needs replacement of parts, the mechanic can take more than 15 hours. Assuming the mechanic takes 12 hours and charges you $140 per hour, you will pay $1,680 to have the engine fixed and installed. However, the rates per hour will depend on the mechanic you visit and the work the engine needs.

After buying a new, used, or rebuilt engine, have at least $3,000 for labor and other associated costs.

Are There Other Costs Associated with Engine Replacement?

A new or rebuilt engine has significantly lower installation costs. After buying a new engine, you need a few items such as coolant fluid, oil, and other fluids. These will cost you $100 or less.

If you go for a used engine, you will need to replace all worn parts and fix parts that might make the engine not to run. The overall cost will depend on the nature of the damages on the engine and the hourly rate of the mechanic who works on it. With a used engine, you will spend more on labor and parts.

Besides replacing the engine, there are ancillary parts that might need replacement. It is not mandatory for you to replace the hoses, belts, water pump, fuel pump, and exhaust manifolds. However, replacing the engine might necessitate the need to replace these parts.

Consult with a mechanic and see whether there are parts that might need replacement. If, for instance, you need to replace the water pump to serve the new engine, consider the cost of a new one and the labor costs for water pump installation.

What Makes the 5.7 Hemi Engine Special?

The hemisphere shape of the 5.7 Hemi increases the pressure in the combustion chamber. Given that the ignition plug is near the engine, the pressure from the engine results in more pressure peak. This means that the engine burns fuel faster and this leads to enhanced efficacy.

The valves in the engine tilt to intersect the dome of the engine’s chamber top. This increases the diameter of the valves thereby making the flow into and out of the chamber unimpeded.

Hemi engines last long, thanks to their strong engineering and heavy nature. In the long run, the engine is more reliable, and you can expect fewer breaks.

Again, the engine is powerful as its design makes it ideal for racing and for hauling and towing trucks. Ram trucks now use the 5.7 Hemi engine, thanks to its efficiency and ability to generate more power. Because the combustion in Hemi engines is fast, vehicles fitted with the engine show fast acceleration and can even produce the sound almost as that of a V8.

If you enjoy a powerful car for racing or towing cargo, you can go for a 5.7 Hemi engine. The engine offers a sense of adventure and allows you to haul or tow more.

Are There Any Downsides to Installing a 5.7 Hemi Engine?

The Hemi engine is great when you need your Dodge Challenger to accelerate faster and have more power. However, the engine is heavier, thanks to its dome design. It increases the curb weight of the vehicles you install it in, and this affects fuel efficiency.

If you plan to replace a different engine with a 5.7 Hemi engine, you will see a significant drop in mpg and a significant increase in performance.

How Much Does It Cost To Replace a 5.7 Hemi Engine?

The engines are also more expensive. You can buy other types of engines at $4,000 while new, but that is the cost of a rebuilt Hemi engine. A new Hemi engine costs about twice the cost of other engines.

If you can overlook these three factors and go for the power and durability of the engine, the 5.7 Hemi engine will serve you well.

If you have another engine, is it worth to replace it with a 5.7 Hemi engine?

The answer to this question depends on how much it will cost you. There are places when you can do engine swaps and spend about 3.5 grand to get the engine running in your car. However, swapping the old for a new engine might not be legal in your area.

Before you get a new engine, consider all the costs and compare that to a new or used car running a 5.7 Hemi engine. If your car cost you $20,000, and the engine will cost you $12,000 to replace, it would be wise to buy a $28,000 car already running a Hemi engine.

Before shopping for engine, talk to your mechanic. The mechanic will assess the condition of your car or truck and estimate the labor costs and the cost of ancillary parts that need replacement. This way, you can create a better budget.

  1. I have a 2005 Dodge Durango that has a 5.7L Mangum. I got 450,000 miles out of it. I love my 2005 Durango size and weight.
    I just want to replace the engine and transmission. Could you please give me an
    estimated cost? Also a good estimate on the labor for replacement.
    Is it unusual to get that many miles?
    Thank you in advance for your help.
