The 5 Most Common Dodge, Jeep & Chrysler 3.6L Pentastar Engine Problems

Your 3.6 Liter Pentastar engine will act up if you drive a car for a long time. Let's find out what things can cause the issues

1. Your Cylinder Heads Might Go Through A Sudden Failure

Cylinder heads really can do that. I know, I was pretty shocked too, but the condition is more serious than you would think.

What Is A Cylinder Head?

You first need to know what a cylinder head is. By definition, a cylinder head is the end cover of a cylinder in an internal combustion engine.

Essentially, the cylinder head is meant to close the engine’s combustion chamber from the very top.

The failure’s main cause may just be overheating the valve seats on cylinder number 2.

Cylinder heads are known to:

  • Provide mounting structure for many components.
  • Control the heat given off by the engine.
  • Take the compression from combustion pressure.

How Can I Tell What happened

It might seem confusing, but some simple ways can be used to know what happened.

The common indicators of a problem include your check 3.6 Pentastar engine light constantly being on, random misfires within your engine, a constant ticking sound coming from your engine and even a sudden power loss observed.

All of these problems probably show you a lot more than you realize, although you may not realize it at the moment itself.

Ways To Fix The Issue

Sadly, the only way to fix the problem is to replace the cylinder heads.

The process may be expensive, yet if you want your problem to be solved in the long term, this might be the only way.

2. The Rocker Arm Creates More Problems Than You Would Think

You might be thinking of what your rocker arm has to do with anything. What you don’t know is the impact it holds.

Understanding The Part

The rocker arm is probably the most important part of the 3.6 Pentastar engine. However, you might confuse the problem with one of the cylinder heads.

The rocker head is meant to help the transmission of the movement of the camshaft involved towards the intake and exhaust valves of the engine.

The use of the part is more important in the opening and closing of the valves, which makes their impact stronger on the engine’s workings.

What Problems Are Created?

Your engine might start ticking constantly. Having such a thing happen is dangerous, especially if you do not know why the action is happening.

The diagnostic trouble code showing up is a huge indicator of something being wrong with your engine.

If there is something wrong with the rocker arm, the code is bound to show up. Misfires are also pretty common.

The rocker arm causes your engine to:

  • Stop performing in the best kind of way.
  • Begin to display problems within.
  • Become very difficult to deal with normally.

Ways To Improve The Condition Of Your Engine

Replacing the broken part is the only way to deal with the problem. Since the part can only be replaced, the part is also heavily expensive.

3. Problems In Your Cooling System Could Be Dangerous For Your Car

Overheating is such a common thing between the engine and how we understand it.

But what causes overheating, and how can such a problem be contained?

Emphasis On Cooling Systems

Cooling systems are what they sound like; they are meant to keep your 3.6 Pentastar engine cool in case of overheating.

The cooling system within your car is basically what helps keep it extremely well kept and at a normal temperature.

Cooling systems include the water pump and the radiator, which are prone to instant damage if not taken care of.

Some other areas that may fail include the heater core and oil cooler, but these are generally not the biggest reason for the problem.

Understanding The Problem

You should be concerned with the problem because it can cause overheating.

Overheating the engine is pretty common compared to other problems, yet the existence of such a thing has a big impact.

If the cooling systems are down, the overheating problem can get way out of hand.

Why Is A Solution Important?

The biggest solution to the problem mentioned is a general repair to whatever area has been affected. Expenses might be tough for some, but overall, repairs aren’t that bad.

The importance of the repairs lies in actually saving your engine to be able to work again.

During the repair, make sure to:

  • Avoid using your car too much.
  • Keep looking out for any extra indicators.
  • Take care not to have the same issue arise again.

4. Having Oil Pump Failures Might Lead To Bigger Consequences Than You Would Think

As you can tell, your oil is probably the most important thing in your car. Without oil, the car would not even move at all. Imagine why oil pump failures are so dangerous if that is the case.

The Problem Itself

Having your oil being unable to pump through the 3.6 Pentastar engine is a serious problem in itself.

The lack of oil flow causes the engine to burn out very easily and hence causes you and your engine too much trouble.

To explain it better, consider the topic of oil pump failure as another way of saying that the oil pressure is too low.

Having a low oil pressure is never a good sign, and if you have such an issue with your car, you should probably get the issue checked.

How To Solve The Issue

Solving such an issue lies in ensuring you have enough oil in the engine and getting your engine checked once in a while.

Both of these will make sure that your engine stops malfunctioning randomly and the oil pressure remains constant throughout your entire driving experience.

However, both can be a little hard to maintain constantly, so make sure you take care of them at least once a while.

The engine can begin to:

  • Splutter and stall for no reason at all.
  • Have a sudden loss of power in it.
  • Get the accumulation of sand particles leading to bigger problems.

Why It Is So Important

Like anything else, getting your engine checked is a common thing you should be worried about.

The maintenance and checkups are important because finding out the oil flow is low early on can help you prevent it.

5. Premature Wear Of The Engine Causes Excessive Worry In Buyers

Your engine is a delicate thing. The motor may seem tough but taking care of such a thing is so important for many reasons, including wear and tear.

Where It Can Be Noticed The Most

If you just bought your 3.6 Pentastar engine yet, you can already see some wear and tear; you might need to worry a little bit.

The premature wear of the engine can be noticed the most in actually looking at the engine to see how it seems.

You should keep a close eye on how your engine looks just to keep the engine in check anyway.

If you notice any wear and tear that is not justified, your engine might be having the issue of premature wear and tear mentioned.

How To Fix The Problem

The simplest way to fix wear and tear is to be careful while you use your engine. If you are too rough with the engine, the motor might just get destroyed way before the allotted time.

But if you take care, the motor will last you longer. Proper maintenance and less rough use will fix your problem right up without any extra measures.

Is It Something To Worry About?

Your premature wear is not something to worry about.

But the wear might lead to the engine not working properly throughout your experience, so don’t you think it is better to take care from the start?

You should take care to:

  • Keep your engine in check constantly.
  • Avoid roughly using the engine for no reason.
  • Choose your engine carefully to suit your vehicle.
