Bag It: Oil Change Tips to Keep It Simple, and Clean
Next, install your new filter. Finding the oil tube and threading the new filter onto the tube requires finesse and a bit of luck!
What is a Variable Geometry Turbocharger?
Up on a pedestal (and rightfully so), this Holset HE351 VGT (above) is the key to managing intake air pressure for economy, power and emissions.
CP4 Fuel Injection Pump Preventive Maintenance
There has been a lot of discussion about the 2019-2020 Ram 6.7 CGI Cummins Turbo Diesel trucks that were equipped with the Bosch CP4 fuel injection pump. A few people have “the sky is falling” attitude, while most others are not concerned at all about the new for Cummins pump choice. When we were in Columbus for the Cummins 100th anniversary celebration in 2019, we were told by the engineers that the reason for the change was to reach the higher fuel pressures required for stricter emissions. This sounded reasonable,…
Third Generation Dodge/Cummins Purchase Criteria
WISH I’D KNOWN THAT(Buying a 2003-2009 Third Generation Truck) TDR members are very good at holding on to their old magazines. Likewise they know that indexes of previous articles were published yearly until year 2009. These important archives were compiled by Bob and Jeannette Vallier. These valuable yearly indexes are found in Issues 65, 61, 57, 53, 49, (deduct 4), etc. Then in 2009, we implemented a digital search of TDR magazines back to Issue 40 at the Turbo Diesel Register website. Join the Turbo Diesel Register to view digital…
Ram Turbo Diesel Low Pressure Fuel System Problems
We all see much discussion on the TDR web forums and in the TDR publications regarding performance/drivability issues, which are often traced to a low pressure fuel delivery problem. Although the narrative that follows is specific to the 12-valve Turbo Diesel trucks, model year ’94 to early ‘98 (pre 24-valve engine), the discussion on the components from the fuel tank (float and sending unit) to the fuel transfer pump apply to all Second Generation trucks. The term low pressure fuel delivery system covers the components from the fuel tank up…
Dodge Cummins Trouble Codes Discussion
In the “Idle Clatter” column in the Turbo Diesel Register, Issue 89, we briefly discussed the dashboard check engine light (CEL) and what it means. As a TDR member you can download the diagnostic trouble codes (DTCs) that turned on the check engine light using a code reader/scan tool and interpret what they mean. You then can know where to look to fix the problem. A good mid-priced scan tool is therefore the next recommended item to go into your tool kit. The scan tool is plugged into the OBD2…
Maintaining Your Dodge Cummins Fuel Pump and Injectors
The Cummins diesel is a longevity engine. When serviced properly, the engine should last 500,000 to a million miles between teardowns. Peripherals like the turbocharger, fuel injectors and the fuel pump, however, can wear out or fail much earlier. A well maintained fuel system can keep injectors going for 250,000 miles or more. The original common rail diesel injectors and CP3 pump in my 2005 Ram have been trouble free for 180,000 miles now. These injectors have delivered good performance and fuel efficiency. There are no signs of spray pattern…
Your Dodge Ram’s A/C System
Are the summer months in your truck spent with the old-school “2-60” air conditioning (two windows down at 60mph)? A properly operating HVAC system provides comfort and safety. The pages of many prior issues of the Turbo Diesel Register magazines have been devoted to the removal of the instrument panel to replace a leaky air conditioning evaporator core (‘98-‘02), leaking heater core, flimsy blend air doors (‘03-current), etc. And you’ll find some of the A/C parts for the DIY-er at Geno’s Garage. Instead of covering “how to change a part,”…
