5 Common Problems With the 3.6L Pentastar V6 Engines

The most common problem with the 3.6 engine is a knocking sound that can be heard when the engine is idling. This is caused by a loose piston pin or connecting rod bearing.

Some common issues include stalling, hesitating, and misfiring. These can all be caused by a variety of different things, so it’s important to get your Jeep checked out by a qualified mechanic if you’re experiencing any of these issues.

Here are five typical issues with the 3.6L Pentastar V6 engine that we regularly fix.

1. Check the Engine Light

A check engine light may illuminate if your automobile misfires and the most typical reason for a misfire with a check engine light involves cylinder head failure. Overheating valve seats of cylinder #2 cause cylinder head failure. This is especially prevalent in Jeep Wranglers. However, depending on the year and mileage of your car, this issue may be covered by an extended warranty.

2. Cooling system

If the engine begins overheating, or if you’re experiencing coolant leaks, heating issues, or a/c difficulties, you might have a cooling system malfunction. This seems to be due to both a water pump as well a radiator issue that is preventing coolant from flowing correctly through the engine. Depending on your car, this may also result in either a check engine indicator or a default code.

3. Oil pump

Failures of oil pumps are a severe problem since they might result in a shortage of oil flow. The ECU should detect a decrease in oil flow promptly and do all possible to avoid additional harm. Its 3.6L oil pump problems seem to be partial failures rather than full failures.

That’s amazing news because the computer should restrict the rpm and power soon. No additional harm should occur as long as the oil is circulating through the engine as well as the engine is not overworked.

4. Cylinder head (2011-2013)

This is a nice problem to start with since it predominantly affects late 2011-2013 Pentastar engines. Early 3.6L V6s had cylinder head problems mostly on the left bank. Overheating of both the valve seats of cylinder #2 is the underlying reason.

Fiat-Chrysler fixed the problem in mid-2013 by using reinforced valve guides with seats. They also tried their hardest to make things right for the clients. In 2011, 2012, and select 2013 models, FCA prolonged the 3.6L Pentastar coverage to 10 years with 150,000 miles for both the left cylinder heads.

5. Rocker Arm

This issue is often mistaken with the one mentioned above. It’s logical given that the rocker’s arms are placed in the cylinder head. However, not all Pentastar rocker arm issues are the same. Cam followers are another name for rocker’s arms.

For this issue, FCA released a service bulletin, which we’ve photographed here. As of the 2014 bulletin, there is a replacement section. Some later Pentastar 3.6L engines, however, exhibit the same issues. As a result, it seems that the upgraded section isn’t a great solution.

Solve the problems with the 3.6L Pentastar V6 Engines

1. Troubleshoot Engine Warnings

  • Look for a major issue that requires rapid care. Examine your dashboard gauges as well as lights for signs of low oil pressure and overheating.
  • Try tightening the gas cap.
  • Reduce the speed and load.
  • If built-in diagnostic services are available, use them.

2. Check the Cooling system

We’ll keep this brief because this section is general but not focused on a single topic. Most cooling system issues aren’t too expensive or difficult to fix on your own. Depending on the nature of the issue, you might wind up paying $200-800 at the repair shop.

However, because of the sand difficulties mentioned above, you may need to repair many pieces. Expenses may begin to mount at this point.

3. Oil pump Monitoring

A malfunctioning oil pump may be prevented if indeed the vehicle is maintained and repaired on a regular basis. Oil pumps are built to last, and it is rare that you will ever have a faulty oil pump.

However, if you observe anyone of the symptoms indicated above, it is essential to get your car evaluated, diagnosed, and serviced as soon as possible to extend the life of your engine.

4. Cylinder head replacement

The 3.6L Pentastar’s cylinder head replacement is not inexpensive. Again, the majority of early vehicles should be covered by the warranty extension. If not covered by warranty, cylinder head replacement might cost thousands of dollars. It’s also worth noting that cylinder head failure may occur at any time. However, it is not a prevalent problem with subsequent engines.

5. Rocker Arm Repair

Surprisingly, several people seem to have reported dealerships replacing the complete cylinder head for this issue. The cylinder head does not need to be removed for this service. Cam follower replacement, on the other hand, is not inexpensive.

Because the valve covers should be removed, it is a somewhat time-consuming process. This repair must be left to experienced mechanics or do-it-yourselfers. Fortunately, the components are reasonably priced. The majority of Pentastar rocker arm repair expenses are labor.

The job will cost between $500 and $1,000. While you’re in there, you may as well repair each of the rocker’s arms.
