Accepted Answer

You have to start by removing the engine front cover before taking off the A/C Compressor bracket power steering hose retainer then disconnecting the intermediate Steering Shaft. First disconnect the a/c pipe and hose connections from the Engine Mount lower nuts before using a socket to remove the A/C Compressor bracket bolts for relocation. Start by draining the engine oil and removing the transmission oil cooler pipe retainer at the engine's right side. Before removing the Oil Pan, install the engine support fixture then secure its wing nuts to free up space for installation. Inspect and clean the Oil Pan only if its disassembly becomes needed. First install the needed parts of the Oil Pan then put the Oil Pan in place afterward lower the engine through the engine support fixture wing nut adjustment to mount the engine at the frame before removing the engine support fixture. Installation begins with the transmission oil cooler pipe retainer followed by adding new engine oil after which the A/C Compressor bracket mounts with the A/C Compressor. After installing the Engine Mount lower nuts use the intermediate Steering Shaft to reconnect it while you add the power steering hose retainer to the A/C Compressor bracket then reinstall the engine front cover.

First, if the spare part has a rotation system (4 WD) remove the front Differential followed by the vice motor Starter, engine shield bolts and engine shield. Depending on the situation, remove the Oil Pan skid plate by removing the bolts, and then remove the crossbar and its bolts. Next, remove the transmission cover bolt and cover, drain engine oil and remove engine Oil Filter remembering to replace Drain Plug and Oil Filter till it is snug. For a car that has the 4l60-e automatic transmission, the transmission bolt on the right side needs to be removed along with the right side stud and the left side bottom bolt. In case you have the 4l80-e automatic transmission, then pull out the converter cover bolts. Disconnect the oil level sensor electrical connector , remove the battery cable channel bolt, move the channel pin out of the Oil Pan tab , delete the engine wiring harness clip from the positive battery cable clip and positive battery cable clip from the positive battery cable clip then remove the engine oil cooler lines and positive battery cable clip bolt and clip. Numb all the Oil Pan bolts together with the Oil Pan while taking care not to introduce foreign material to the oil passages. If needed, drill out the Oil Pan gasket retaining rivets and remove the gasket, since they must be discarded. Jay clean and check the engine Oil Pan before installation in such a way that alignment is critical here as rear bolt positions here give mounting points for transmission bellhousing. Add 5 mm (0.20 inch) bead of sealant gm U.S. P/N 12378190, or equivalent, to the engine block on the tabs of the front and rear cover gaskets that extend into the Oil Pan surface. Align the oil gallery passages in the Oil Pan and the engine block with the Oil Pan gasket and then attach the pre-assembled gasket to the pan and attach the Oil Pan, gasket, and bolts to the engine block in a snug condition without over-tightening the bolts. When given the 4l80-e automatic transmission, fit the transmission converter cover bolt until tight, and in the 4l60-e automatic transmission, the transmission bolt is installed as well as the study on the right side, then the bottom bolt on the left side. Tighten Oil Pan, and Oil Pan to Oil Pan front cover bolts to 25 nm (18 ft. Lbs.), Oil Pan to rear cover bolt to 12 nm (106 inch lbs.) and bellhousing, converter cover and transmission bolts/stud to 50 nm (37 ft. Lbs). Reinstall the positive battery cable clip to the Oil Pan bolt screwing the clip bolt to 9nm (80 inch lbs), install the engine oil cooler lines, the engine wiring harness clip, and reinstall the positive battery cable clip to the positive battery cable clip. Slip the channel pin into the Oil Pan tab, fit the battery cable channel bolt and tighten it to 12n (106in lb). Check the oil level sensor "s, install the transmission cover and bolt with a tightness of 12 nm (106 inch lbs.), install crossbar and its bolts with a tightness of 100 nm (74 ft. Lbs.). In case it applies, fix the Oil Pan skid plate and its bolts, which need to be fixed at 20 nm (15 ft. Lbs) then the engine shield, which should also be tightly bolted, at 20 nm (15 ft. Lbs). Lastly, reinstall the Starter motor, the front Differential if also had 4wd, and change the engine oil as well as its Oil Filter.

Question 3

How to Properly Service and Replace the Oil Pan on Cadillac XLR?

Accepted Answer

Replacing the Oil Pan requires front suspension crossmember removal and draining the engine oil before removing the engine Oil Filter to empty the fluid contents. Disconnection of automatic transmission fluid cooler lines should be followed by removal of the engine oil level sensor electrical connector before extracting the oil level sensor and securing all Oil Pan bolts for easy removal of the Oil Pan. Begin by cleaning the Oil Pan before applying a new Oil Pan gasket to the oil manifold plate and setting the Oil Pan into position against the crankcase with a 0.50 mm (0.020 inch) space forward from the engine block's rear face. Following Oil Pan retaining bolt installation, use a torque tool to secure them at 25 nm (18 ft. Lbs.). The oil Drain Plug installation requires 25 nm (18 ft. Lbs.) of torque. Fasten the engine oil level sensor into place with 20 nm (15 ft. Lbs.) before you connect the electrical connector to the sensor and install the automatic transmission fluid cooler lines. After tightening the new engine Oil Filter to 30 nm (22 ft. Lbs.) you should install the Oil Pan Drain Plug with 25 nm (18 ft. Lbs.) torque. Place the front suspension crossmember back into position before filling the crankcase with proper engine oil grade and quantity while checking transmission fluid level and testing the engine for any leaking areas.
