The longevity of a 5.7 Hemi engine ranges from 250,000 to 300,000 miles. Once you reach this number, the engine performance declines significantly. It will eventually die.

Nonetheless, the 5.7 Hemi engine may last less than 250,000 miles. It depends on the extent of usage and the environmental conditions. For instance, the more you use it on rough roads and harsh conditions, the shorter the lifespan.

Most Common 5.7 Hemi Engine Problems

While most 5.7 Hemi engines last up to 300,000 miles, some factors will speed up wear. Hence, it might not maximize the expected lifespan.

Here are some of the potential problems:

  • Engine Tick

A loud ticking noise is a common tell-tale sign of a weak 5.7 Hemi engine. The sooner you act, the easier it is to salvage the engine. Otherwise, it will be too late and the repairs will be costly. It also compromises performance.

The engine ticks when there is a failure of exhaust manifold bolts, fault filters, and seized lifter roller. Most of these problems are apparent in models that have been made since 2009.

As soon as your engine ticks, it calls for immediate inspection. Look for broken or loose parts. Replace or repair when necessary.

  • Lifter and Cam Failure

Diagnosing lifter and cam failure is difficult. It has many signs and symptoms, most of which pinpoint other general engine problems. Some of the most common things that happen include ticking noise, misfiring, and locking up camshafts.

One of the most common reasons for lifter cam and failure is lack of lubrication, making it difficult for the components to move. Incorrect valve train geometry, lack of valve to piston clearance, excessive valve spring pressure, and incorrect valve lash are also likely culprits.

  • Damaged Exhaust Manifold Bolts

During its lifetime, it is almost sure that a 5.7 Hemi engine will have faulty exhaust manifold bolts. This leads to leaks, which will prevent the engine from eliminating toxic gases. The leak from the bolts will also minimize power and make fuel consumption inefficient.

Like many engine problems, a quick way to diagnose the problems in exhaust manifold bolts is to listen to unusual sounds. It is noisy when it is loose or damaged. You will hear the tick in the engine as soon as the problem starts.

Luckily, repairing bolts in the exhaust manifold is easy and affordable. You don’t even need to run to a local mechanic and pay a pro to do the job. With the right tools and a bit of patience, changing the bolts is an easy DIY task.

  • Issues With the Multi-Displacement System

The multi-displacement system is a cylinder deactivation technology by Chrysler. It is an exclusive innovation that delivers plenty of benefits, such as up to 20% better fuel efficiency. Even with fuel savings, the driving experience remains the same.

Despite the promises of the multi-displacement system, some people noted that it is prone to problems. It may not activate and reactivate smoothly, which makes the experience unnatural. It also results in a loud noise, especially when your vehicle has an aftermarket exhaust system.

How to Make 5.7 Hemi Engine Last Longer: Care and Maintenance Tips

The best way to prolong the lifespan of 5.7 Hemi engines is to implement proper care and maintenance.

Here are things you can do to maintain optimal performance even after years of use and accruing significant mileage:

Create a Schedule

Make your 5.7 Hemi engine longer-lasting by having a maintenance schedule. It varies depending on the extent of use or the recommendations of the vehicle manufacturer. In most instances, however, here is a good schedule:

  • Every 8,000 Miles or Six Months: Replace the engine filter and oil, rotate tires to minimize strain on the engine
  • Every 16,000 Miles or 12 Months: Replace the engine filter and oil, check the brake linings and exhaust, check the front suspension
  • Every 24,000 Miles or 18 Months: Replace the engine filter and oil, check the CV joints, rotate the tires, check the exhaust
  • Every 32,000 Miles or 24 Months: Replace the engine filter and oil, replace the brake linings, change the air conditioning filter, replace spark plugs
  • Every 56,000 Miles or 42 Months: Replace the engine filter and oil, replace the front suspension, change the automatic suspension fluid
  • Every 96,000 Miles or 72 Months: Replace the engine filter and oil, replace the brake linings, check the CV joints

Monitor Tire Pressure

The overall performance and lifespan of the 5.7 Hemi engine depend on several factors, including tire pressure. Follow the manufacturer’s recommendations for optimal performance. It will keep you safe and sound on the road while also maintaining efficiency.

If you drive with the tire pressure too low, drag and friction increase. On the other hand, when it is too much, excessive tread wear is possible, which also minimizes the grip.

Let It Breathe

Like humans, engines need room to breathe. Otherwise, oxygen limitations will restrict their functionality. Not to mention, it will make them less fuel-efficient and the emissions will increase. Overheating is also a problem.

Letting the engine breathe is possible by keeping it clean. More so, you should replace the filters when necessary. It will make them more effective in catching pollutants and contaminants that obstruct the different components.

Check the Coolant Levels

As a part of regular care and maintenance, inspect the coolant, making sure that it is at the right level. Ensure that it is enough to prevent the engine from overheating. If it is due for a replacement, find the right coolant, making sure that it is compatible with the setup of your engine.

Change the Oil Regularly

In the maintenance schedule earlier mentioned, a regular oil change is one of the most important.

Over time, oil becomes less effective and efficient. It accumulates debris and sludge. Replacing it at a regular interval does a lot to prolong the life of the engine while improving the overall performance of your vehicle. You should also use only the best oil for 5.7 hemi.

Practice Good Driving

One of the most important factors that will prolong the lifespan of your 5.7 Hemi engine is responsible driving. From sudden braking to early shifting, bad driving habits will ruin your engine. Know your car by heart and treat it with respect. In the long run, your car will make it up to you by delivering top-notch performance.
