eTORQUE SYSTEM (Optional Mild Hybrid)
Many modern Ram 1500 trucks with the DODGE RAM 3.6L ENGINE feature eTorque, a 48-volt mild hybrid system. It does not drive the wheels directly like a full hybrid, but it improves:
-
Start-stop functionality
-
Low-end torque (extra 90 lb-ft at launch)
-
Fuel economy
-
Regenerative braking
It’s especially noticeable during low-speed acceleration and stop/start traffic driving.
MAINTENANCE & RELIABILITY DODGE RAM 3.6L ENGINE
The DODGE RAM 3.6L ENGINE is one of FCA/Stellantis’ most widely used engines. It’s in millions of vehicles — Ram, Jeep, Dodge, Chrysler.
Common Maintenance Items:
Service | Interval |
---|---|
Oil change | Every 5,000–7,500 miles |
Spark plugs | Every 100,000 miles |
Coolant flush | Every 10 years or 150,000 miles |
Air filter | Every 15,000–30,000 miles |
Transmission service | Every 60,000–100,000 miles (depending on driving conditions) |
Known Issues (mostly pre-2016 versions):
-
Oil Cooler Leaks – Cracks in plastic oil cooler housing (upgraded to aluminum aftermarket).
-
Cylinder Head Failure – On early models (mostly 2011–2013).
-
Cam Phaser Noise – Rattling sounds from timing system (less common after 2015).
-
Carbon Buildup – Less than direct injection engines, but regular oil changes help.
PERFORMANCE & TOWING
The DODGE RAM 3.6L ENGINE is more than adequate for daily driving and light-duty towing.
Towing by Configuration (Ram 1500):
Cab/Bed | Max Towing (approx) |
---|---|
Regular Cab, 2WD | ~7,730 lbs |
Crew Cab, 4WD | ~6,280 lbs |
ProMaster (Van) | ~6,900 lbs (GVWR dependent) |
Payload Capacity: Up to ~2,300 lbs depending on trim
PERFORMANCE UPGRADES DODGE RAM 3.6L ENGINE
