2002 Cadillac Seville Parts Questions & Experts Answers

• Q: How to replace the engine oil and oil filter on 2002 Cadillac Seville?

  A: Begin by safely raising the vehicle and support it in place and direct the oil drain pan underneath the engine oil Drain Plug before removing the plug. Before new installation inspect and replace the Drain Plug followed by examination of the Oil Pan sealing surface which receives a repair or replacement if needed for the Oil Pan. Starting with the Oil Filter remove it from the opening and prepare both the adapter and sealing area before conducting any necessary replacements or repairs. Before attaching the new filter add oil to it. Apply a thin layer of clean oil on its gasket before installation by doing a 3/4 to 1 full turn when the gasket touches the mounting surface. Install the Drain Plug on the engine then tighten it to 20 nm (15 ft. Lbs.) before lowering the vehicle to add new engine oil while looking for leakage after engine startup. Any time the oil pump needs replacement or removal requires oil system priming by maintaining 7 quarts of engine oil with a full Oil Filter and making additional additions if required. Turn off the power lead connectors from the ignition modules for thirty seconds then apply power before starting the engine. Examine the dic because it could show a low oil pressure warning along with any noticeable engine sounds. Permanent oil pressure assessment requires engine stoppage followed by sensor removal from the adapter which can be followed by correct gauge installation. The system has been primed after starting the engine because there's normal oil pressure reading along with typical sounds underneath. Engine oil should be forced under pressure through the engine block outlet port before reinstalling the adapter and engine start-up when no oil pressure readings appear during cranking procedures. To proceed further stop the engine then return the oil pressure sensor before checking the display for pressure warning messages while performing any essential switch repairs.
