To change the oil in your 2021 Ram 2500, first, ensure the truck is on a level surface and the engine is cool. Remove the oil drain plug and let the old oil drain completely into a pan. Replace the drain plug and remove the old oil filter. Install a new filter and pour new oil into the engine. Check the oil level with the dipstick to ensure it is at the proper level.
The recommended tire pressure for a 2021 Ram 2500 is typically 60 psi for the front tires and 80 psi for the rear tires. However, you should always check the information on the tire placard located on the driver's side door jamb for the most accurate information.
To reset the service light on your Ram 2500, turn the ignition to the "On/Run" position without starting the engine. Fully depress the accelerator pedal slowly three times within 10 seconds. Turn the ignition off and then start the engine to ensure the service light is reset.
The 2021 Ram 2500 is designed to run on regular unleaded gasoline with an octane rating of 87 or higher. If you have a diesel engine model, use ultra-low sulfur diesel fuel. Always refer to your owner's manual for specific fuel recommendations.
To pair your smartphone with the Uconnect system, activate Bluetooth on your phone. On the Uconnect screen, go to "Phone" > "Add Device" and select your phone from the list. Follow the prompts to enter the passcode displayed on the Uconnect screen into your phone to complete the pairing process.
If your engine overheats, turn off the air conditioning and turn on the heater to help dissipate the heat. Pull over safely and turn off the engine. Allow it to cool before checking the coolant level. Do not attempt to open the radiator cap while the engine is hot. If necessary, add coolant or seek assistance from a professional mechanic.
To engage the 4WD system in your Ram 2500, shift the transmission into Neutral or Park. Use the transfer case lever or switch to select the desired 4WD mode. Once engaged, an indicator light will confirm the system is active. Refer to your owner's manual for specific instructions based on your model's configuration.
The towing capacity of the 2021 Ram 2500 varies depending on the engine and configuration but can range up to 19,680 pounds when properly equipped. Always consult your owner's manual and ensure your truck is equipped with the right towing package.
To replace a headlight bulb on your 2021 Ram 2500, open the hood and locate the back of the headlight assembly. Remove the cover and disconnect the electrical connector. Remove the old bulb and replace it with a new one, ensuring not to touch the glass of the new bulb with your fingers. Reconnect the electrical connector and replace the cover.
Follow the maintenance schedule outlined in your owner's manual, which typically includes oil changes every 8,000 miles, tire rotations every 10,000 miles, brake inspections every 20,000 miles, and a full-service check every 30,000 miles. Regular maintenance ensures optimal performance and longevity of your vehicle.
