Now, let’s dive into the discussion regarding each of the common 2021 Ram eTorque problems.
Faulty Oil Pump
In a Ram eTorque system, there’s a special part called the oil pump, and it plays a crucial role. Imagine it as the engine’s personal oil circulator. Its job is to move oil all around the engine to keep everything running smoothly.
Now, if this oil pump starts acting up, you might run into some engine problems. Things like low oil pressure, the engine overheating, or, in the worst cases, the engine giving up entirely.
There are a few reasons why this might happen. First of all, the oil pump can wear out if your vehicle is driven non-stop for an extended period. Furthermore, if the engine gets too hot, the oil can lose its ability to lubricate, causing the oil pump to work too hard and overheating the engine, sometimes giving up.
Additionally, when it’s freezing outside, the oil can become thick and sluggish, making it difficult for the oil pump to work effectively. This extra effort can wear out the oil pump too soon.
Solution: Replace the Oil Pump
Whenever there is any problem with the oil pump, normally, you will get a message on the dashboard, or the warning light will light on.
The best action is to get to a mechanic as soon as possible and get it diagnosed. Normally, the go-to solution is to get the oil pump replaced. It should cost you around $915 to $1100.
Cylinder Head Failure
In a Ram eTorque system, there’s a crucial part called the cylinder head. It can sometimes run into problems; if the engine gets too hot, it can put too much pressure on the cylinder head, causing it to bend, crack, or develop leaks.
Usually, overheating is the result of a poor cooling system, low coolant levels, or a malfunctioning thermostat.
Now, if you ignore these issues, you’re in for some trouble. A blown head gasket can be one result, and that’s a big deal. It can cause the engine to misfire, leaks in the coolant system, and a drop in engine power. So, don’t underestimate the importance of a healthy cylinder head!
Solution: Replace the Cylinder Head
Once again, if the cylinder head is malfunctioning, then it is best to head over to the mechanic and get it fixed. The best option is to replace the cylinder head. It should cost you around $2500.
Rocker Arm Problems
Rocker arms tend to malfunction due to wear and tear and if there is too much overheating. When the engine overheats, the rocker’s arm has to work much harder than it should. There can be bending, cracking, or nasty leaks caused by this.
It is often due to a cooling system that’s not up to snuff, low coolant levels, or a thermostat that’s gone rogue.
But overheating isn’t the only concern. Neglecting basic engine upkeep, like changing the oil and coolant, can lead to a buildup of gunk and debris in the engine. It can clog up the rocker’s arm or even damage it. So, maintain that rocker arm regularly if you want it to last!
Solution: Replace the Rocker Arm
The best action here is to go to any servicing station and get the rocker arm removed. It is risky to go by with a malfunctioning rocker arm. Let the mechanic check the truck and remove it.
However, if you are looking for a DIY guide, then check this tutorial about how to replace rocker arms.
Cooling System Problems
As evident by now, the cooling system issue is to be taken seriously, or else you can get problems related to the oil pump and cylinder head.
The radiator, radiator fan, hoses, thermostat, and water pump of your 2021 RAM 1500 can wear out or become damaged over time, causing cooling system problems.
The internal heating system can be affected by low coolant levels, resulting in overheating. Common issues encompass radiator and hose leaks, as well as thermostat failures, which may manifest as coolant loss.
Coolant leaks can persist without completely depleting the coolant supply, potentially causing rust and component damage. If you observe any of these symptoms, it’s advisable to visit a reputable service center.
A frequent culprit behind coolant leaks is a malfunctioning EGR cooler, which can develop cracks due to thermal stress.
In some cases, coolant vaporization may even pose a risk of engine fires, a concern addressed by Ram but with delays impacting vehicle owners.
This issue can also affect vehicles equipped with EGR systems designed to reduce emissions, as the EGR cooler employs both coolant and airflow to regulate temperature.
However, there is also a problem with manufacturing. FCA (Fiat Chrysler Automobiles) employs a sand-casting process in the production of Pentastar engines. It is crucial to clear any residual sand deposits before installing the cylinder heads.
Occasionally, these sand deposits are not adequately removed during manufacturing. As a result, some engines leave the factory with these sand deposits still intact.
Engines that retain these sand deposits may encounter cooling system issues, leading to problems associated with the Pentastar engine.
Solution: Drain Out the Cooling System
First, you need to drain out the cooling system if there is any sand or other impurities within. The steps are relatively simple, and this video will help you with the process.
Solution: Remove the Damaged Component
Head over to any repair shop and get the mechanic to diagnose the system. If there is leakage or damage to the system, such as the radiator, thermostat, or water pump, then get it replaced as soon as possible.
Battery Draining
Customers often report that the 12-volt battery powering the eTorque system quickly depletes. When the battery drains rapidly, the eTorque system can shut down or malfunction.
Besides malfunctioning batteries, defective alternators, and corroded battery cable posts, other factors contribute to battery drain. A relay stuck in the activated position or an exposed wire can cause battery depletion due to an amperage draw.
Solution: Replace the Battery
If the battery is damaged, it is better to replace the battery. The steps are not that difficult. Just check this:
For a detailed guideline on replacing the battery. It will help you check the battery condition along with the steps for replacing the battery.
However, you can also visit the mechanic to get the battery replaced. But this will cost you around $520 to $720.
