What are the steps in changing the oil in a 1986 Lincoln Town Car

1) Purchase appropriate oil filter, sump drain bung washer and chosen engine oil.
2) Prepare an oil pan, sump bung wrench and oil filter removal tool (check access to oil filter to be sure that your tool is suitable.)
3) Run the engine until its warm to hot.
4) With the car jacked up and secured, remove engine oil filler cap and remove engine oil sump drain bung and allow oil to flow out into your drain pan. Keep an eye on your oil and make sure it doesn't overflow from your drain pan.

5) Refit sump bung with new washer and tighten. Do not over-tighten, and be especially careful when tightening into an alluminium sump.


6) Remove oil filter. Oil will flow out from this filter when removing, so your drain pan will need to be under the filter housing when removing.


7) Run a smear of clean engine oil around the filter rubber seal and refit new filter. Tighten hand tight only. Do NOT crank this filter super tight as you may damage the rubber seal and even the filter casing which can impede oil flow.


8) Refill engine with proper quantity of oil. If you cannot find how much oil your engine is supposed to take, then refill with the same quantity of oil which you drained out.


9) Restart the engine while checking the oil pressure warning light on the dash. The warning light may stay on for three or four seconds and then go out. If this light stays on for longer, then stop your engine and check for oil leaks at the filter body and sump drain bung.


10) Once the engine oil pressure warning light is off after starting, stop the engine and check the engine oil level (with vehicle on the flat and off any axle stands.)


11) Road test the vehicle, driving it for a mile or two before re-checking for oil leaks under the engine bay and engine oil quantity.
