RAM DIESEL VEHICLES
Dodge, especially under its Ram Trucks brand (now RAM as a separate brand from Dodge), has been well-known for its diesel-powered vehicles, particularly in the pickup truck segment. Here’s an overview of notable Dodge/RAM diesel vehicles and the common issues associated with them:
RAM 1500 (Previously Dodge Ram 1500)
- Engine: 3.0L EcoDiesel V6
- Common Issues:
- EGR Valve Failure: Issues with the Exhaust Gas Recirculation (EGR) system can lead to reduced engine performance and increased emissions.
- DPF Clogging: Frequent short trips can lead to Diesel Particulate Filter (DPF) blockages, as regenerations cannot complete properly.
- Oil Dilution: The regeneration process can lead to oil dilution, which may require more frequent oil changes.
- Turbocharger Problems: Some units have experienced turbocharger failures or performance issues, often related to maintenance neglect.
RAM 2500 and 3500 (Previously Dodge Ram 2500 and 3500)
- Engine: 6.7L Cummins Turbo Diesel I6
- Common Issues:
- Turbocharger Failure: The variable geometry turbo can experience actuator failures or vane sticking, leading to reduced performance.
- Fuel System Problems: High-pressure fuel pumps and injectors can suffer from issues, sometimes due to contaminated fuel.
- DPF Clogging: As with other diesel engines, DPF clogging can occur, particularly in trucks used for frequent short trips.
- EGR Problems: Blockages or failures within the EGR system can result in drivability issues and increased emissions.
RAM Chassis Cab Models
- Engine: 6.7L Cummins Turbo Diesel I6 (varies slightly in configuration from 2500/3500)
- Common Issues:
- Transmission Concerns: Heavy-duty use can lead to transmission issues, though this is not directly related to the diesel engine.
- Turbo and Emissions System: Shared with the RAM 2500/3500, issues can arise with the turbocharger, DPF, and EGR system.
RAM ProMaster Diesel
- Engine:
- 3.0L EcoDiesel I4 (This engine was offered in the earlier versions of the ProMaster and might not be available in the latest models as RAM has shifted focus more towards gasoline engines.)
- Common Issues:
- EGR System Problems: The Exhaust Gas Recirculation (EGR) valve can become clogged or fail, which can lead to performance issues and increased emissions.
- DPF Clogging: The Diesel Particulate Filter (DPF) can become clogged, particularly if the van is primarily used for short trips that don’t allow for proper regeneration cycles.
- DEF System Issues: Problems with the Diesel Exhaust Fluid (DEF) system, such as sensor malfunctions or injection failures, might lead to warning indicators and potential power reduction.
- Turbocharger Concerns: The turbocharger can suffer from issues such as actuator failure or reduced performance, particularly if maintenance such as oil changes is neglected.
- Fuel Injector Problems: Diesel fuel injectors may wear out over time, potentially leading to reduced performance or fuel efficiency.
The shift in recent years has been towards gasoline engines in the ProMaster line due to market demand and emissions regulations, explaining the greater focus on those models. For those using or purchasing an older ProMaster diesel, it's advisable to have a thorough check by a qualified technician, especially focusing on the emissions and fuel systems, to ensure ongoing reliability.
General Considerations for Dodge/RAM Diesel Vehicles
- Maintenance: These vehicles especially benefit from regular maintenance. Keeping up with oil changes, using high-quality fuel, and ensuring the air and fuel filters are replaced as needed is vital to prevent failures.
- Diesel Exhaust Fluid (DEF) System: Problems with the DEF system, such as injector and sensor failures, can lead to error messages and reduced power modes.
- Suitable Driving Conditions: To properly maintain the emissions systems, diesel RAM trucks perform best with regular long-distance driving that allows for the DPF to regenerate effectively.
- Heavy-Duty Usage: While designed for heavy-duty work, it's crucial to ensure proper maintenance and that vehicles are not overloaded beyond recommended specifications, as this can accelerate wear.
RAM trucks have a strong reputation for towing and heavy-duty performance due to their durable diesel engines, but staying on top of maintenance is key to avoiding common issues. Always consult a trusted mechanic or dealership, especially before purchasing used models, to identify any potential problems.
