Chevrolet 12597151 Pan,Oil

The manufacturer recommends that the oil pan only be removed with the engine out of the vehicle. Remove the bolts and detach the oil pan. Don't pry between the block and pan or damage to the sealing surfaces may result and oil leaks could develop. If the pan is stuck, dislodge it with a block of wood and a hammer. Note: Some of the fasteners are studs. Before removing them, make a mark on the pan to indicate their location for reassembly. Use a scraper to remove all traces of sealant from the pan and block, then clean the mating surfaces with lacquer thinner or acetone. Install a new rubber half-circle seal to the rear main bearing cap. Apply a thin coat of RTV sealant to the ends of the rubber seal, where it fits into the main bearing cap. Apply a 3/16-inch wide by 1/8-inch thick bead of RTV sealant around the oil pan flange and the front circle of the pan, where it contacts the timing chain cover. Install the oil pan and tighten the mounting bolts. Start at the center of the pan and work out toward the ends in a spiral pattern. The remainder of installation is reverse of removal. Reinstall the engine and lower the vehicle. Install a new filter and add oil to the engine, then start the engine and check for leaks.

Lubricants and fluids used on your vehicle are hazardous waste and must be disposed of properly; when disposal is required, place the waste into a sealable container and deliver it to a service station, auto parts store, or other facility that accepts hazardous waste for recycling. Begin by disconnecting the cable from the negative terminal of the battery, ensuring to disable the anti-theft feature on models equipped with an anti-theft audio system. Raise the vehicle and support it securely on jackstands, then drain the engine oil and remove the oil filter. If necessary for clearance, detach the exhaust pipes from the exhaust manifolds using penetrating oil spray to ease nut removal. Remove strut rods if the engine is equipped with them, then take off the bellhousing lower cover from the transmission and the starter motor and shield if equipped. Rotate the crankshaft clockwise using the vibration damper bolt until the timing mark is in the 6 o'clock position, disconnect the transmission oil cooler lines or engine oil cooler lines from the oil pan and adapter, capping the lines to prevent contamination and leakage. For 1996 and later models, remove the oil filter adapter and rubber bellhousing plugs, and if applicable, remove and discard the oil level sensor and the crankshaft position sensor wiring harness from the retainer. Remove the oil pan bolts, nuts, and studs, noting their locations, and carefully separate the oil pan from the block without prying between them to avoid damaging the sealing surfaces. Clean the gasket sealing surfaces with lacquer thinner or acetone, ensuring the bolt holes are clean, and check the flanges for distortion on steel-type oil pans. For models from 1985 to 1995, apply RTV sealant to the corners of the semi-circular cutouts at both ends of the pan before installing the new gasket, while for 1996 and later models, apply a bead of RTV sealant to the block-to-timing chain cover joint and the rear main seal-to-block joint before installing the new gasket onto the oil pan. Position the oil pan against the engine block and install the fasteners finger tight, then tighten the oil pan bolts/nuts in three equal steps to the specified torque, starting at the center and working outwards in a spiral pattern for older models. For models equipped with an oil level sensor, install a new sensor and tighten securely. Ensure the oil pan is aligned correctly as it serves as structural reinforcement between the engine and transmission, tightening the bolts/nuts in three steps to the specified torque while verifying the gap between the oil pan and the transmission bell housing is 0.010 inch or less. The remaining installation steps are the reverse of removal, and remember to refill the engine with oil before starting the engine and checking for leaks around the oil pan.

Install the oil pan and tighten the mounting bolts to the specified torque, starting at the center of the pan and working out toward the ends in a spiral pattern.

After removing the oil pan bolts, the oil pan should be separated carefully, and the gasket surfaces should be cleaned.

During installation, the oil pan bolts/studs should be tightened in sequence to ensure proper alignment and sealing.

The initial steps involve disconnecting the negative battery cable, draining the oil, and removing the starter motor, two engine-to-bellhousing braces, and the lower part of the bellhousing cover.

The oil pan mounting bolts/nuts should be removed, and it's important to note the location of studs and brackets to ensure proper reinstallation during assembly.
