What Is the 5.7 Hemi?

I will keep this simple. The 5.7 Hemi is a V8 engine from Chrysler. You see it in Dodge, Ram (Brand), Jeep, and the Chrysler 300C. It has 5.7L (displacement) or 345 cubic inches. It is a pushrod engine. It is naturally aspirated. People love the sound. People love the shove.

You find it in the Ram 1500, Dodge Charger, Dodge Challenger, Jeep Grand Cherokee, Dodge Durango, and Dodge Aspen. It also shows up in some Mopar builds and SRT trims in the past. This motor pairs well with the TorqueFlite 8 and the ZF 8HP. Those are smooth and quick transmissions that fit the Hemi’s torque curve.

From the start, the 5.7 Hemi mixed old-school muscle with new tech. It uses VVT (Variable Valve Timing). Many trucks use MDS (Multi-Displacement System), also known as cylinder deactivation. That shuts off four cylinders at cruise to save gas.

How Did the 5.7 Hemi Evolve?

The 5.7 Hemi came with the third-generation Hemi (engine family). Early years ran from 2003 to 2008. In 2009, the motor got updates many folks call the Eagle (engine generation). Eagle added VVT, better flow in the cylinder head, and tuned intake manifold changes. Owners saw more horsepower and torque.

You may hear the word Apache (engine generation). That name fits the 6.4L Hemi more than the 5.7L. I mention it because buyers compare the 5.7 Hemi vs 6.4 Hemi a lot. The 6.4 Apache makes more power. The 5.7 Eagle runs leaner and costs less to own for many drivers.

Is the 5.7 Hemi still made? In many cars and trucks, it is being phased out for new turbo six engines. Some models kept it through recent years. The Hemi engine history runs deep. The brand built its name on that half-dome combustion chamber. The legacy still draws buyers today.

How Much Horsepower and Torque Does It Make?

Here’s the fun part. Early 5.7 Hemis made around 340–345 horsepower and 375–390 lb-ft of torque. With the Eagle update, numbers moved to about 355–395 horsepower and 410–420 lb-ft of torque. Your exact number depends on the vehicle and year.

I have driven a Challenger 5.7 Hemi and a Charger 5.7 Hemi. Both pull strong. In a Ram 1500 5.7 Hemi, the grunt helps with trailers and loads. The Hemi engine horsepower increase from Eagle is real. It feels like a thicker mid-range. It gives you that easy pass on a two-lane road.

Want more? Some owners add a 5.7 Hemi supercharger kit or performance upgrades 5.7 Hemi like cams and headers. You can add Hemi engine performance chips and a 5.7 Hemi tune. A proper 5.7 Hemi tune-up also helps restore lost power.

Does It Tow Well and How Does It Drive?

The 5.7 Hemi makes trucks feel lively. You get quick jumps from lights and clean pulls on grades. A good torque converter 5.7 Hemi and the ZF 8HP keep it in the sweet spot. You can tow and haul with confidence. If you ask “Is 5.7 Hemi good for towing?” the answer is yes for half-ton class needs.

In cars, it feels smooth at cruise and bold when you press the pedal. It has that 5.7 Hemi exhaust sound that fans crave. With VVT, it keeps the motor responsive in town. On the highway, MDS can hold four-cylinder mode for better fuel economy.

Want better manners? A clean throttle body and fresh spark plugs help. A healthy PCM (Powertrain Control Module) and ECM (Engine Control Module) tune matters too.

Is the 5.7 Hemi Reliable?

Now the big question. Yes, the 5.7 Hemi can be reliable. I have seen trucks cross 150,000 to 250,000+ miles with normal care. I have also seen a lifter tick 5.7 Hemi turn into a cam and lifter failure 5.7 Hemi. That hurts wallets. The truth sits in the middle.

Let’s use PAS to make it clear.

• Problem: Known weak spots like lifter & camshaft failure, exhaust manifold leak 5.7 Hemi, MDS Hemi issues, or oil consumption 5.7 Hemi.
• Agitate: These can snowball. A small tick grows louder. A broken exhaust manifold bolt adds a leak. Rough MDS shifts beat on lifters. You waste fuel and time.
• Solution: Stay ahead of it. Use the best oil for 5.7 Hemi. Keep smart 5.7 Hemi maintenance. Listen for changes. Fix small things fast. Many owners avoid big failures by acting early.

Sites like CarComplaints.com, Consumer Reports, JD Power, and Motor Trend note the same themes. The 5.7 Hemi brings power and charm. It also needs love and clean oil.

What Are the Most Common 5.7 Hemi Problems?

You asked for the truth. Here it is in plain words.

• Lifter & Camshaft Failure
• The “Hemi tick” can start soft. It may be a stuck or worn lifter. Over time, it can chew a camshaft lobe. Causes include poor oil habits, MDS stress, and weak oil flow to a few lifters. You may see a misfire like P0300 5.7 Hemi misfire. If you wait too long, it can ruin the top end.
• Exhaust Manifold Leaks
• Heat cycles can warp exhaust manifolds or snap bolts. You hear a tick at cold start. It gets quieter when warm. You may smell exhaust. In some cases, you get a light on.
• MDS Malfunctions
• Multi-Displacement System uses oil-fed solenoids. Hemi VVT solenoid problems or MDS solenoid clogs can cause rough idle and poor fuel economy 5.7 Hemi Ram. MDS can add wear to lifters in some cases. Some owners choose a How to delete MDS on 5.7 Hemi approach with a tune. Know your local laws first.
• Oil Consumption
• Some motors use more oil. Causes include piston ring issues, valve guides, or the PCV system. If you do not check the oil, you risk damage. Watch for 5.7 Hemi oil pressure problems too.
• Other Issues
• Hemi coolant leak from a water pump or hose. 5.7 Hemi overheating issues if coolant runs low. Rare timing chain wear. 5.7 Hemi cold start noise on some engines. Worn valve springs or a weak oil pump in high-mile units. A tired torque converter can add shudder.

You also need to track sensors. A bad 5.7 Hemi crankshaft position sensor or 5.7 Hemi camshaft sensor can cause stalling. A weak 5.7 Hemi coolant temperature sensor can confuse fans and fuel trims.

How Long Does a 5.7 Hemi Last?

I have seen these engines run strong past 200,000 miles. Many owners report Hemi engine life expectancy of 150,000–250,000+ miles. Two things matter most. Maintenance and how you drive.

If you tow heavy and skip 5.7 Hemi service intervals, you invite trouble. If you keep oil clean and fix small leaks, the motor rewards you. If you ignore a tick, you risk a 5.7 Hemi rebuild cost or a full cost of 5.7 Hemi engine replacement. That can break a budget.

One more note. The 5.7 Hemi uses a chain not a belt. So “Does 5.7 Hemi have a timing belt or chain?” It has a chain. The motor is an interference engine. That means parts can hit if timing fails. The chain is robust. Still, good oil helps it live.

What Maintenance Keeps It Healthy?

You can stack the deck in your favor. Here is what I do and what I tell friends.

• Oil Changes
• Use a good synthetic. Brands like Pennzoil and Valvoline show up often in owner success stories. Follow the right weight from the manual. Shorten the interval if you have MDS or you tow. Clean oil helps lifters survive. Use the right Hemi oil filter type.
• Cooling System
• Check coolant. Fix drips. Keep an eye on the radiator, water pump, and hoses. A flush on time saves headaches. A Hemi engine block heater helps in deep cold starts.
• Ignition and Fuel
• Replace spark plugs on time. Use the best spark plugs for 5.7 Hemi that fit your year. Inspect coil packs and fuel injectors. Clean the 5.7 Hemi throttle body. Change the 5.7 Hemi transmission fluid as the maker says.
• Listen and Inspect
• Learn your engine’s normal sounds. A fresh 5.7 Hemi engine startup noise is not normal if it appears out of nowhere. Watch for Hemi engine knocking at idle. Look for Hemi engine oil leaks at the valve cover gasket or oil pan. Check the 5.7 Hemi intake manifold gasket if idle goes rough.
• Fix Small Things Fast
• A small MDS issue can snowball. A light tick can turn into a cam job. Keep up with 5.7 Hemi engine diagnostics. Read 5.7 Hemi engine codes. Look up Hemi engine service manual notes. Check for recalls and TSBs.

What Are the Pros and Cons?

Here is the straight talk.

• Pros
• Raw power & torque for size and class
• Excellent towing capability
• Distinctive V8 sound
• Proven platform when you keep it clean and serviced
• Widespread availability of parts & service through Mopar and aftermarket
• Cons
• Known lifter & camshaft concerns
• Exhaust manifold bolts and leaks
• Potentially high repair costs
• Fuel economy sits in “okay” for a V8 not “great”
• Sensitivity to maintenance neglect

Buying a Used 5.7 Hemi: What Should You Look For?

I never buy a used Hemi without a full P.P.I. Here is my playbook.

• Check service records. Clean oil changes win.
• Listen at cold start and warm idle. A light tick can be an exhaust manifold leak. A deep tick from the valley can be a lifter.
• Scan for codes. Watch for P0300 and misfires that move around.
• Look for oil consumption signs. Ask the seller how often they add oil.
• Inspect for leaks. Look at valve cover gaskets, oil pump weeps, water pump trails, and coolant crust.
• Test drive with a scan tool. Watch MDS engage. Feel the TorqueFlite 8 or ZF 8HP shift quality. Check for torque converter shudder.

Some owners install MDS delete kits or upgraded lifters. If done right, that can help. If done wrong, it can cause new issues. Ask who did the work. Ask for parts lists and torque specs used.

How Does It Compare to Other Engines?

People compare the 5.7 Hemi to the Ford Coyote and GM EcoTec3 V8s. Those engines shine too. The Hemi brings a big low-end hit and a classic feel. The Coyote likes to rev. The EcoTec3 leans on direct injection and AFM/DFM tricks.

Inside the Hemi family, buyers ask 5.7 Hemi vs 6.4 Hemi. The 6.4 Apache makes more power and torque. It also drinks more fuel. The 5.7 hits a sweet spot for cost and use. If you want an all-around motor for daily life and some fun, the 5.7 still fits.

Is the 5.7 Hemi still made? It has been phased out in some lines. The new Hurricane turbo six steps in. Yet a used Hemi engine for sale is easy to find. You can also buy a Hemi engine remanufactured unit or Hemi engine rebuild kits if you want to freshen yours.
