  Q: How to replace the oil pan on 2WD on Cadillac Escalade ESV?

  A: Vehicle service begins by raising the vehicle then supporting it to perform the Oil Pan replacement on 2wd vehicles. Owners of 1500 models should disconnect skid plate bolts before removing the skid base plate except in cases where no skid plate exists. Owners of 2500 models need to disarm rear Oil Pan skid plate bolts before taking out front bolts and skid plate if skid plate exists. Begin by hanging the steering rack downwards after unbolted. Place a proper drain pan under the Oil Pan Drain Plug to drain all oil which you must tighten properly later. The drain pan needs installation beneath the Oil Filter before removing it (437) until all fluid drains before reinstalling it securely. First remove the bolts on both transmission covers before breaking away the left and right side transmission cover pieces and then remove all crossbar nuts and bar elements from both series types. 2 lower transmission bolts need removal for vehicles equipped with either a 4l60-e/4l70-e or 4l80-e automatic transmission. During 6l80-e automatic transmission service remove both the lower left transmission bolt and the lower right transmission stud. Start by removing the transmission oil level sensor engine harness electrical connector then detach the engine harness clip from the transmission oil cooler line bracket before removing the battery cable channel bolt to slide the channel pin out of the Oil Pan tab. Cars with transmission cooler lines will need those lines removed from the clip before continuing to remove the transmission oil cooler line clip bolt and clip from the Oil Pan along with the Oil Pan bolts and Oil Pan itself. Before reusing the Oil Pan users should drill out any necessary Oil Pan Gasket rivets before removing and discarding both gasket and rivets. The critical step for structural Oil Pan alignment requires new Oil Pan Gasket installation and prohibits gasket reuse. Position the new Oil Pan Gasket onto the Oil Pan before applying a 5 mm (0.20 in) bead of sealant that spans 20 mm (0.80 in) on both engine block tabs of the front and rear cover gaskets. After this, fit one Oil Pan bolt through a hole and into the gasket. Position the Oil Pan while securing all remaining Oil Pan bolts until they achieve a secure fit. Before moving to the next step you should install both the lower right transmission stud and lower left transmission bolt to a secure position on vehicles with 6l80-e automatic transmission components. The installation of 2 lower transmission bolts reaches their necessary snugness on both 4l80-e and 4l60-e/4l70-e automatic transmissions. Install the Oil Pan completing tightness at 25 n.m (18 lb ft) and Oil Pan-to-Oil Pan front cover bolts at 25 n.m (18 lb ft), Oil Pan-to-rear cover bolts at 12 n.m (106 lb in), and transmission bolts/stud at 50 n.m (37 lb ft). The transmission oil cooler line needs its clip installed on top of the Oil Pan and the bolt tightened to 9 n.m force (80 lb in metric). Position the channel onto the Oil Pan tab before sliding the channel pin through the tab. Then bolt and tighten the battery cable channel to 12 n.m (106 lb in). Finally if your vehicle has cooler lines install them to the clip. Connect the oil level sensor electrical wires through the engine harness connector then bolt the engine harness clip onto the transmission oil cooler line bracket. Both vehicle series require the original adhesive patch removal, denatured alcohol cleaning of bolts followed by gm p/n 12345493 threadlocking (Canadian P/N 10953488) application before crossbar installation. Install the crossbar and crossbar bolts and nuts according to these torque specifications: 120 n.m (89 lb ft) for 2500 series and 100 n.m (74 lb ft) for 1500 series. Start by fitting the left side transmission cover before installing and torquing its cover bolt to 12 n.m (106 lb in) and following with right side transmission cover bolt installation. When using an existing Oil Pan install a new Oil Filter (437), apply clean engine oil to the seal before tightening the filter to specification at 30 n.m (22 lb ft). Screw the Oil Pan Drain Plug (430) at 25 n.m (18 lb ft) tightness. Then lift the steering rack into position for bolt installation before securing the left bolts to 200 n.m (148 lb ft) and right bolts to 100 n.m (74 lb ft). Users should install the Oil Pan skid plate by tightening the rear bolts on 2500 series vehicles before putting on front bolts (if equipped) and securing them to 28 n.m (21 lb ft). The 1500 series requires installation and bolt tightening of the skid plate to match the specified values. Lower the vehicle before filling the engine with new engine oil and begin engine operation for leak checks.
