Key Specs of the 2022 RAM 1500 3.6L V6 Engine

The gasoline-fed 3.6L (3,564 cc) engine of the present Ram 1500 has a V6 configuration. Compared to an inline-four, this kind of engine is designed to generate plenty of torque at low RPMs and better power delivery. The combination of this with the eTorque technology for a mild-hybrid setup further aids in providing a temporary boost during acceleration.

The ground-breaking eTorque mild hybrid system replaces the engine's traditional alternator with a 48-volt battery-powered, belt-driven motor generator that improves performance, efficiency, payload, towing capabilities, energy recuperation, and drivability.

In addition, the adoption of a dual overhead camshaft (DOHC) with four valves per cylinder makes way for better airflow at high engine speeds which in turn results in more optimized output. DOHC engines also allow the spark plug to be placed directly in the middle of the combustion chamber, promoting the efficient transformation of fuel into energy. Meanwhile, the integration of a variable valve timing (VVT) ensures the right amount of air and fuel mixture within the different operating conditions of the engine to supplement its performance and efficiency while reducing its emissions.

Alongside them is a timing chain with inverted teeth. The smaller links of the chain engage at a slower impact speed, which reduces noise. In conjunction with the smaller pitch chain, the number of teeth on the sprockets is increased, enhancing the meshing frequency and reducing noise and vibration significantly.

Moreover, the utilization of aluminum material in the construction of the 3.6L eTorque Pentastar V6 translates to less weight and more efficiency without sacrificing durability compared to its counterparts with the conventional cast-iron build. Of course, less weight contributes to enhanced fuel economy, too.

Crunching the numbers, the unit has a bore of 94 mm and a stroke of 85.6 mm. These figures help produce a compression ratio of 11.3:1. The high compression ratio of the 3.6L V6 is indicative of improved thermal efficiency. A high ratio allows an engine to extract more energy from the combustion process and it permits higher combustion temperatures while consuming less fuel.

The output produced by the 3.6L V6 Pentastar is 305 hp at 6,400 rpm and 269 lb-ft of torque at 4,800 rpm. The matching eTorque mild-hybrid tech puts around 90 lb-ft of torque into the engine on the get-go for a good 6.6-second acceleration time from 0 to 60 mph with the help of the pickup truck's 8-speed automatic transmission as well.

Finally, the engine can tow up to 7,660 lbs when properly equipped while its fuel economy is 17 and 25 mpg for city and highway trips, respectively.

Durability of the 2022 RAM 1500 3.6L V6 Engine

A straightforward answer regarding the longevity of the 2022 Ram 1500 V6 engine is a whopping 250,000 to 300,000 miles before requiring an overhaul or replacement. If driven at an average of 15,000 miles annually, that would make the auto last for around 16 years to two decades.

The figures obviously come with the condition that you shouldn't skip its regular maintenance and that the truck is utilized responsibly though. Likewise, the early signs of problems with it should be taken care of without delay to ensure its integrity.

Most Common Problems of the 2022 RAM 1500 3.6L V6 Engine

The 2022 Ram 1500 3.6L V6 Engine is generally packaged as a reliable engine. However, there are a few problems that tend to crop up with it in some users. The most common are the following:

1. Cylinder Head Failure

Based on a number of complaints about the 2022 RAM 1500 3.6L V6 engine, one of the identified common problems about it is cylinder head failure that's particularly caused by an overheating valve seat on cylinder #2. This overheating issue can be due to the misalignment of the fuel injector.

When this happens, it will cause the exhaust valve on that cylinder to overheat and eventually warp. As a result, compression will start to drop on that cylinder which will cause a rough idle and a loss of power. The check engine light will also come on.

This is a serious problem that should be addressed as soon as possible because if left unchecked, it could cause major engine damage. To fix this, the cylinder head will need to be replaced. The good news is that this is a covered repair under the RAM 1500's powertrain warranty.

If you're experiencing any of these symptoms, it's best to take your RAM 1500 to a certified dealer or mechanic for a diagnosis. They will be able to tell you for sure if the cylinder head needs to be replaced.

2. Rocker Arm Fault

The rocker arm is an important component in the 2022 Ram 1500 3.6L V6 engine. Its main function is to transfer the motion of the camshaft to the valves. It also helps to keep the valves properly lubricated and cooled. If there are any problems with the rocker arm, it can cause a number of symptoms, including engine misfires, a loss of power, and increased fuel consumption.

There are a few possible causes of rocker arm problems. One is an issue with the valve lash adjusters. Another possibility is that the rocker arms themselves are worn out or damaged. In some cases, it may be necessary to replace the entire rocker arm assembly.

If you suspect that there is a problem with the rocker arm in your Ram engine, it's important to have it checked out and repaired by a qualified mechanic as soon as possible. If your pickup truck is still covered by warranty, better bring it to the dealer to save on repairs.

3. Cooling System Failure

The cooling system of the 2022 Ram 1500 3.6L V6 engine is vital to its proper functioning. It helps to keep the engine operating at its optimal temperature, preventing it from overheating and sustaining damage.

There are a few symptoms that can indicate that there may be something wrong with the cooling system such as the engine running hot, the temperature gauge needle getting higher than normal, there is steam coming from under the hood, and the engine making strange noises.

If you notice any of these symptoms, it's important to act immediately. The first step is to check the coolant level and add more if needed. Make sure that it's not contaminated, too. If the coolant level and quality are fine, the next step is to check the radiator hoses. Look for any leaks or cracks and have the damaged hose replaced.

Another possible cause of a cooling system problem is a faulty thermostat. This can cause the engine to overheat. The thermostat can be replaced easily.

If the cooling system problem is not resolved, it could lead to engine damage or even fire. Therefore, it's important to address the problem in a timely manner. Again, take advantage of your auto warranty to get the most out of it.

4. Oil Pump Malfunction

The oil pump circulates oil throughout the critical parts of the engine, lubricating all of the moving parts. If the oil pump fails, then the engine will quickly seize up and fail. That's why it's important to be able to diagnose the symptoms of oil pump failure so that you can get the problem fixed before it's too late.

One of the first symptoms of oil pump failure is unusually loud engine noise. Another symptom of oil pump failure is intermittent drops in engine power.

If you suspect that the oil pump is failing, then the best course of action is to take the car to your trusted mechanic or dealership and have them diagnose the problem. They will likely need to replace the oil pump to solve the issue.

Conclusion

When it comes to power and reliability, the 2022 Ram 1500 3.6L eTorque Pentastar V6 engine is definitely a smart choice. For a pickup with a powerful engine, the fuel economy is also relatively decent. Despite a few issues, the engine is still regarded as very durable, and with proper care, it's good between 250,000 to 300,000 mileage.
