Hyundai 21510-2B020 Pan Assembly-Engine Oil

The upper oil pan on the other hand cannot be removed unless the engine is pulled out or removed from the car. This removal should be done after taking off the cable of the battery negative terminal and when the rear wheels are blocked and the front of the vehicle is hiked on two jackstands. Take off the engine splash shield if installed, expel the engine oil, and take out the oil filter and oil dipper. Subsequently, you should unscrew the pan bolts and then take off the oil pan, paying attention to the variation in the length of bolts used. In case the pan is seized to gasket land, use a small screwdriver or putty to pry it out without damaging the mating surfaces as this will lead to oil leakage. The lower oil pan can be separated from the upper oil pan while the other part is still fixed into the engine. In regard to the upper oil pan, the procedure involves the removal of the engine and next the lower oil pan. Take out the oil pick-up screen bolts/screws and the screen and finally the rear main oil seal. Remove the upper pan bolts; special attention paid to the variation of the bolt length; if you are having trouble, use pry bar with caution not to harm the surface that interconnects the two. When fitting the upper oil pan apply a scraper to remove the old sealant from the block and oil pan, clean the mating surfaces to ensure the threaded bolt holes in the upper pan is clean. Examine the shelf of the oil pan flange for unevenness and spread RTV sealer of 3/16-inch thickness on the sealing surface for the installation of the pan within 15 minutes. Put the oil pan onto the ladder assembly and screw in the bolts loosely and then use the star pattern to tighten the bolts to the required torque. The rest of the installation procedure can be done and it is the reverse of the removal procedures and after starting the engine, look at the oil pressure and possible leaks. Before installing the lower oil pan, the first step is the removal of all the old sealant, cleaning of the mating surfaces, application of RTV sealant and putting in the lower oil pan finally tightening the bolts in several processes to achieve the maximum torque set for it and testing of the engine for pressure of oil and leakage.

Disconnect the cable from the negative terminal of the battery.
