2005 Cadillac STS Oil Pan Parts Questions & Experts Answers

• Q: How to replace the oil pan on 2005 Cadillac STS?

  A: Start by installing the engine support fixture while draining the engine oil before commencing replacement of the Oil Pan. You must start by taking out the front frame and front differential carrier before unhooking the engine oil level sensor electrical connector and pulling out the sensor at the Oil Pan. You should take out the Oil Pan bolts while remembering that the Oil Pan Gasket functions for multiple uses unless it shows signs of damage so you should leave it in the groove except when absolutely needed. Clean the Oil Pan before inspecting it after removal. Clean the seal groove from oil residue before carefully placing the new Oil Pan seal into position across both directions of the pan groove. Position the Oil Pan against the crankcase before installing all bolts while tightening them according to this order to reach 10 nm (89 inch lbs.). Screw the engine oil level sensor into the Oil Pan while tightening it to 10 nm (89 inch lbs.) before connecting its electrical connector. Following front differential carrier and front frame installation add engine oil before taking out the engine support fixture. Verify for any oil drips when the engine begins to run.
