Step-by-Step DIY Installation Guide for RAM 2500

Replacing your own oil filter on the RAM 2500 takes approximately Moderate (30-45 mins) and saves an estimated $35 – $50 maintenance add-on in dealership service fees.

01

Park the RAM 2500 on a level surface, engage the emergency parking brake, and allow the engine to cool completely (at least 30 minutes if working near exhaust or cooling lines).

02
Disassembly & Removal

Carefully release the factory retention clips and unseat the old component from the RAM 2500.

03
Installation & Torque Calibration

Install your new oil filter ensuring exact seating alignment. Ensure all locking tabs and retention clips snap securely into place.

System Verification & Final Checks

Turn ignition on, verify zero warning lights on the dashboard cluster, and test component functionality under normal operating conditions.

Avoid These Common Installation Mistakes:
  • Never over-torque spark plugs or oil drain plugs into aluminum cylinder heads / oil pans.
  • Always double-check vehicle model year fitment on Amazon before completing checkout.
