2004 Cadillac CTS Oil Dipstick Tube

The proper way is to lubricate the NEW Oil Filter Adapter O-ring with clean engine oil, install the new O-ring into the oil filter adapter groove, position the oil filter adapter to the engine block, install the O-ring onto the oil filter adapter plug, install the oil filter adapter plug, install the left catalytic converter, and then install the oil filter.

The proper way is to install the Oil Pan bolts, the 3 lower transmission mounting bolts, the bolt securing transmission fluid cooler pipes brace, and the front frame, and then fill the engine oil.

The procedure is to position the oil drain pan under the oil pan drain plug, remove the oil pan drain plug and allow the engine oil to drain, clean and inspect the oil pan drain plug, remove the Oil Filter cartridge housing drain plug and allow the engine oil to drain into the drain pan, remove the plastic cap from the oil filter cartridge housing, and then remove the oil filter cartridge from the plastic cap.
