5.7 Hemi Engine Complaints And Problems
The most common Chrysler 300 5.7 complaints and issues with this engine include:
1. Bolts For Exhaust Manifolds
The snapping of exhaust manifold bolts is a common problem for 5.7 Hemi owners. This includes the connections to the back two pistons. The common problem may be explained because the back two of the cylinders are hotter than the others because they are closer to the engine bay. Also, they are harder to cool.
All Chrysler 300 5.7 Hemi owners should expect to eventually have to purchase new exhaust manifold bolts. This is possible as a DIY project if you are a very skilled mechanic. To have the belts replaced, most of us will need to take our car to a mechanic.
2. Hemi “Tick”
The “Hemi tick” is a condition Chrysler 300 5.7 Hemi engines can be prone to.
Some believe this tick is harmless. This group claims that the tick is simply part of the engine’s pushrod design. A pushrod engine has many moving parts, so some extra noise is not unusual. The ticking should not cause problems as long as it isn’t being driven hard.
Others claim that ticks are a problem that can be traced back to several factors, such as faulty lifters or valves or poor fuel.
It’s difficult, if not impossible, to determine the cause of the Hemi tick. This tickling sound is not universally understood.
3. Multi-Displacement Systems (MDS)
Modern Chrysler 300 Hemi engines have a multi-displacement system. When the engine is cruising at a constant, steady speed, the MDS turns off four of its cylinders. This system was designed to increase fuel economy and generally works well.
The MDS itself is not the problem but the system in general. Some Hemi owners claim that their MDS activates and then reactivates with no problems. Others report that the MDS is not functioning smoothly.
Owners report a loud, droning sound that occurs when the engine shuts down and then reactivates the pistons. If the vehicle is equipped with an aftermarket exhaust system, this droning sound will be even more noticeable.
Some 5.7 Hemi owners believe that the MDS might be detrimental to the engine over the long term. It is unlikely that an engine would turn a part of itself off, then switch it back on. This technology is relatively new, and the jury is still out whether it is harmful or beneficial for the engine.
Although the MDS is not necessarily an issue with the 5.7 Hemi, it is something that many owners dislike. There is a simple way to disable the MDS system from the steering wheel.

What Is The Replacement Cost Of Chrysler Hemi Engines?
You know how much a chrysler 300 costs, but replacement costs are also pretty high compared to the buying costs. To replace a 5.7 Hemi-engine will cost between $5,600 to $13,000.

The Chrysler 300 luxury full-size sedan is made in America and features a front-engine, rear-wheel drive, or optional all-wheel drive. With the 5.7 and the next-generation 6.1 Hemi, the Chrysler 300 may be a bit jaded, but it’s still the ultimate American muscle sedan. One punch of the gas pedal and every other sedan around it will have to concede to this Hemi.
The Chrysler 300 5.7 engines are heavy duty. But my suggestion is if you properly take care of these machines, you will get over the issues fast. Hence if you are leaving the engine unattended, then after a certain period, you will face much more problems even if sometimes repairings are not also possible. You directly require replacement solutions.
