Changing The Ram Ecodiesel Fuel Filter: Step-By-Step Guide

Changing the fuel filter on a Ram EcoDiesel truck can be a tricky process. The fuel filter is bolted to a frame rail underneath the vehicle and enclosed in a canister with a spin-off bottom. While some people choose to take their trucks to the dealer to get the fuel filter changed, others opt for a DIY approach. The process involves loosening the canister, draining the fuel, and then replacing the filter. It is important to note that there is only one fuel filter in the Ram EcoDiesel, contrary to what some people may believe. Additionally, there is some debate over the recommended interval for changing the fuel filter, with some people suggesting every 10,000 miles, while others recommend following the manufacturer's guidelines, which suggest changing it at around 30,000 miles.

Drain water from the fuel filter

To drain water from the fuel filter of a Ram EcoDiesel, follow these steps:

First, locate the fuel filter. It is usually found underneath the vehicle, above the rear axle, and next to the fuel tank. Place a container, such as a plastic bag or bucket, under the fuel filter to catch any spills.

Locate the yellow drain screw or valve. Using a Phillips-head screwdriver, loosen the screw. You may need to jiggle or push the screw up and down to allow the water and fuel to drain out completely. Be careful not to spill, as diesel fuel can be harmful to your skin and the environment.

Once the water has drained, tighten the screw back in place before proceeding to change the fuel filter.

It is recommended to drain the water from your fuel filter regularly, especially if you notice any performance issues or smoke while driving. Some recommend doing this at every oil change, or at least twice a year, to ensure the filter is functioning optimally.

If you notice a significant amount of water in your fuel filter, it may be beneficial to use a fuel additive to help disperse the water. Additionally, consider the fuel stations you frequent, as older stations may have more water in their tanks.

By regularly draining water from your fuel filter and maintaining your vehicle, you can help ensure optimal performance and longevity for your Ram EcoDiesel.

Use a fuel filter wrench

To use a fuel filter wrench, follow these steps:

First, loosen the yellow drain screw by a few turns. This will allow any water or diesel fuel to drain out. If you have a Ram EcoDiesel, the yellow drain valve may not function properly, so you may need to break or cut the top off to allow for complete drainage. Alternatively, you can replace the yellow drain valve with a brass valve, which can be removed using a 17mm wrench or socket for more effective drainage.

Next, place a container under the fuel filter to catch any spills. You can use a plastic bag, such as a grocery bag or a Ziploc bag, to catch the fuel, or you can use a container such as an old ice cream bucket or a gallon jug.

Now, use the fuel filter wrench to loosen the filter housing. The fuel filter housing removal tool has four indents that go over the nibs on the filter housing and a 19mm hex head for your wrench or socket. Once the housing is loose, carefully remove it, being careful not to spill any remaining fuel.

At this point, you can replace the fuel filter. Make sure to install the new filter before tightening the housing. This ensures that the seals are seated properly.

Finally, tighten the housing and dispose of the old filter and any spilled fuel properly.

Using a fuel filter wrench can make the process of changing your fuel filter much cleaner and easier, and it can help you avoid a diesel fuel bath.

Check suspension components

To check the suspension components of your Ram EcoDiesel, you'll need to inspect both the front and rear suspension systems.

Inspecting the Front Suspension

• Inspect the strut mounts or shock towers: Open the hood and look to either side. The struts or shock towers will be above each wheel and secured with bolts or nuts. Check that the nuts and bolts are not loose, rusty, or otherwise compromised.
• Measure the ride height: Use a ruler or tape measure to measure the distance from the top of the tire to the bottom of the fender well. Compare the measurements on both sides. While a slight variation is acceptable (up to half an inch), the two sides should be fairly equal.
• Jack up the vehicle: Place a trolley or scissor jack under one of the designated jack points at the front end. Once the car is high enough, place jack stands underneath to support its weight.
• Inspect grease boots and rubber bushings: Get under the vehicle and start at one wheel, looking for black or grey rubber bushings that separate metal components of the suspension. Look for cracks or tears in the bushings, which will need to be replaced if found.
• Check for excess play in the tie rod ends: Locate the power steering box and follow its arms toward the wheels. Check the tie rod ends, which are the connection points between the steering box and the wheels, for excess play.

Inspecting the Rear Suspension

• Jack up the rear of the car: Place a jack under the rear jack points of the vehicle. If the front end is on jack stands, you can leave it in the air, otherwise, lower it and use the stands to support the rear.
• Wipe and inspect the bushings: The rear suspension may be covered in mud and debris, so wipe the bushings clean with a rag and water if needed. Inspect the bushings for signs of damage, such as cracks or tears.
• Inspect bolts and nuts: Check the nuts and bolts for signs of rust and tightness. Use a screwdriver to poke at rusty hardware. If the rust crumbles, the hardware will need to be replaced. Tighten any loose nuts or bolts.

The Bounce Test

Park your vehicle on firm, even ground, like concrete or blacktop. Push down firmly on the front of the vehicle, then release. The suspension should bounce back up and right itself in a single bounce. Repeat this test on the rear of the vehicle, pressing down on the trunk lid. If the suspension bounces multiple times before settling, the shock absorbers may be bad and should be looked at by a professional.

Replace the air conditioning filter

To replace the air conditioning filter on your Ram EcoDiesel, follow these steps:

Park your vehicle on a level surface and engage the parking brake.

Locate the air conditioning filter housing, which is usually found in the engine bay or behind the glove compartment. Refer to your owner's manual if you're unsure of the location.

Remove the old air conditioning filter by opening the filter housing and taking out the old filter. Note the orientation of the filter to ensure you install the new one correctly.

Clean the filter housing with a soft brush or compressed air to remove any debris or dust.

Take the new air conditioning filter and insert it into the housing, ensuring it is properly seated and oriented correctly.

Secure the filter housing by closing it and fastening any clips or screws that hold it in place.

Check your owner's manual for any additional maintenance tasks that may be required, such as resetting the maintenance light or updating the service interval record.

By following these steps, you will help maintain the air quality in your Ram EcoDiesel and keep the air conditioning system functioning efficiently.

Prime the fuel engine

To prime the fuel engine of a Ram EcoDiesel, follow these steps:

• Add a substantial amount of fuel to the tank, approximately 2 to 5 gallons (8 to 19 litres).
• Press the ignition switch twice without your foot on the brake to put the vehicle in "Run" mode. This will activate the in-tank fuel pump for approximately 30 seconds. Repeat this process twice.
• If you have a keyed start truck, cycle the key to the "Run" position a couple of times without starting.
• If you have a push-button start, push the start button with your foot off the brake. This will allow the truck to go into "Run" mode without starting the engine. Do this a couple of times.
• Start the engine using the "Normal Starting" procedure.

It is important to note that you should not open the high-pressure fuel system while the engine is running, as it can cause serious injury or death. Additionally, do not use alcohol or gasoline as a fuel blending agent, as they can be unstable and hazardous when mixed with diesel fuel.
