Question 1

How to Ensure Proper Installation of the Oil Pan on Chevrolet Colorado?

Accepted Answer

To replace the Oil Pan you first need to remove the oil level indicator and tube and the engine protection shield. Drain the engine oil and then remove parts to acquire the clearance for the Oil Pan. For rwd, take off the power steering gear. For the 4wd, the first thing you should be doing is taking out the front propeller shaft, then the differential carrier assembly bushing to frame bolts, and pull towards down while securing the pinion yoke in not to rotate. At this point, pull out the service, plug out the nut attaching the fuel hose/pipe bracket to the transmission and the four lower bolts of the transmission securing them to the Oil Pan. For 4wd also unbolt the power steering gear mounting bolts and pull the power steering gear down for access. Now we can disconnect the engine wiring harness retainers from the Oil Pan, thereafter remove the Oil Pan bolts. Install two bolts in the tapped holes at the rear of the Oil Pan as jack screws, and screw them in evenly to release the Oil Pan from the engine block, and remove the Oil Pan and two bolts from the jack screw holes. Check and clean the sealing surface of the engine block. While mating the Oil Pan, spread a 5.5mm (0.22 in) narrow sealer at the marked and 3mm (0.12 in) spread at the mark while making sure that the sealer does not run on the oil pump pipe and screen assembly. Position the Oil Pan to the engine block so the rear Oil Pan surface is level to the rear block surface. In case transmission is removed, use a straight edge for a requirement of alignment; if installed, make sure the Oil Pan is completely rearward from the transmission mounting surface. Mount the Oil Pan bolts, fitting its side bolts to 25 n.m. (18 lb ft), and its end bolts to 10 n.m (89 lb in). Attach the engine wiring harness retainers to the Oil Pan and for 4wd mount the power steering gear on top of the frame assembly to tighten mounting bolts. Installs the four lower transmission mounting bolts with tightening 50n.m (37 lb ft) and later tightening the nuts connecting the fuel hose/pipe bracket to the transmission 20 n.m (15 lb ft). Mount the service slot plug and relevant parts: for rwd, install the power steering gear; for rwd, install the power steering gear; for 4 wd, position the differential carrier assembly to the frame, install bush to the frame bolt, 152 n.m(112 lb ft), install front propeller shaft. Lastly, after checking that the engine spacer will have no problem fitting into the spare cylinder, install the engine protection shield, the oil level indicator and tube, and fill the engine with oil.

Question 2

How to replace the oil pan on Chevrolet S10?

Accepted Answer

A replacement of the Oil Pan begins with disconnecting the negative cable battery followed by removal of the oil level indicator and front Differential assembly and the Starter unit before removing the transmission cover. Roll out the engine oil through the Oil Pan's Drain Plug before directing it into a proper receptacle. To begin the replacement process disconnect the remote oil filter pipe adapter along with the bolt securing the remote filter hose clip to the Oil Pan and finally remove the stud for wiring harness bracket and transmission oil cooler pipes if installed. Remove access plugs for Oil Pan rear nuts and transmission to Oil Pan bolts yet understand the low oil level sensor needs replacement with a new unit. Once the engine oil level sensor is discarded, technicians should remove all Oil Pan bolts and nuts before discarding the Oil Pan and gasket. Wash every sealing surface between the engine and Oil Pan. The installation process requires applying an adhesive 0.197 inch (5 mm) wide by 1 inch (25 mm) long bead of gm p/n 12346141 or equivalent along the front cover engine block junction and crankshaft rear oil seal housing to engine block junction at the Oil Pan sealing surfaces. When installing the Oil Pan Gasket always use a fresh one and position it when adhesive remains tacky. The Oil Pan should rest either flush or slightly forward facing at most 0.3 mm (0.011 inch) from the rear engine block surface. Set the Oil Pan Gasket into the groove of the Oil Pan before placing it onto the engine block while pressing the gasket into its grooves. First align the Oil Pan to a straight edge prior to applying the Oil Pan bolts with loose nut threads. Then use a feeler gauge to check the pan-to-transmission clearance. The alignment needs repeating if the clearance measurement reaches 0.3 mm (0.011 inch) at any point among the three measurement points. Measure the Oil Pan-to-transmission housing clearance again after tightening the Oil Pan bolts to 25 nm (18 ft. Lbs.) in sequence. Torque the new Oil Pan Drain Plug seal to 25 nm (18 ft. Lbs.) while also installing a new engine oil level sensor that requires 13 nm (115 inch lbs.) of torque. Begin by tightening transmission to Oil Pan bolts to 47 nm (35 ft. Lbs.) while completing the process with access plugs for Oil Pan rear nuts followed by Starter wire harness bracket stud and remote oil filter pipe adapter. Attach the oil filter hose inlet and outlet connection to the Oil Pan by threading a 10 nm (88 inch lbs.) bolt through the pan. Then fasten the transmission cover using 12 nm (106 inch lbs.) bolts. After installing the Starter motor connect the front Differential assembly and oil level indicator before filling the engine with oil and reattaching the negative Battery Cable.
