Acura 11200-P72-010 Engine Oil Pan & Drain Plug

To remove the oil pan, first warm up the engine, drain the oil, and replace the oil filter. Disconnect the cable from the negative terminal of the battery, ensuring you have the correct activation code for the radio if it has an anti-theft system. Raise the vehicle and support it securely on jackstands, then remove the splash shield from under the engine. Next, remove the front exhaust pipe and the bolts securing the oil pan to the engine block. Tap on the pan with a soft-face hammer to break the gasket seal, then detach the oil pan without prying between the block and oil pan mating surfaces. Use a gasket scraper to remove all traces of the old gasket or sealant from both the engine block and oil pan, and remove the seals from each end. Clean the mating surfaces with lacquer thinner or acetone, ensuring the threaded bolt holes in the block are clean. For installation, clean the oil pan with solvent and dry it thoroughly, checking the gasket flanges for distortion. If needed, flatten and restore the gasket surfaces using a hammer on a wood block. Apply a 1/8-inch wide bead of RTV sealant to the oil pan gasket surfaces, ensuring it is applied to the inside edge of the bolt holes. Carefully place the oil pan in position, install the bolts, and tighten them in small increments to the specified torque, starting with the bolts closest to the center and working out in a spiral pattern to avoid overtightening, which could cause leakage. Finally, add oil, run the engine, and check for any oil leaks.

Raise the vehicle and support it securely on jackstands. After that, remove the splash shield from under the engine.
