First, the cable should be disconnected from negative terminal of the battery and the engine oil should be drained along with the oil filter. For models from the year 2005 and down, move to the removal of timing belt and sprocket, oil filter bracket assembled with gasket, the upper oil pan to oil pump bolts and the pump to the engine block bolts, and extract the pump from the front of a model. The next steps are to unscrew the fasteners of the pump cover, the cover, and rotors of the pump, and also do not forget to remove all the remains of the sealant and the previous gasket from the casing of the pump and the block of the engine, and at this time it is necessary to cover the front part of the oil pan with cellophane to prevent contamination by various debris. For models from 2006 and later, those following steps should be done: first, undo the lower oil pan, then undo the oil pump chain cover fasteners, undo the oil pump sprocket bolt the sprocket and chain, and finally, undo the oil pump mounting bolts and take out the pump as a unit. Regarding cleaning all the gear components, first use the solvent: Check for excessive wear or damage on all parts. On the 2005 and earlier models, one has to inspect the oil pressure relief valve sliding surface and the valve spring; if they are damaged, they have to be replaced jointly; the amount of clearances in link, cut, piston, eccentricity, and shaft clearances have to be checked using a feeler gauge. If there is any problem felt with the pump of the 2006 model and the later models, change the pump with a new one. For 2005 and prior models, it's install the new crankshaft seal prying the old one out and using grease or engine oil to lubricate the new seal before fitting it into position. Put the drive and driven rotors to the sides of the pump body, fill the cavity with white grease and put on the cover with new gasket or sealant; conclude with tightening the screws in an interlinking manner. It is necessary to use engine oil to lubricate the oil pressure relief valve before it is fitted, the faces of the case gasket surfaces must be cleaned and it is necessary to fit the oil pump case with a new gasket and tighten the mounting bolts simultaneously in a criss-cross manner. For 2006 and later models, oil pump O-ring, oil pump bolts, the drive chain, and sprocket should be replaced and the oil pump bolt must be tightened. Last of all tighten all components in reverse sequence, put the oil, engage the engine and check the oil pressure and for any leaks, and last recheck the engine oil level.
