The oil pump cannot be sub-assembled or internally examined; thus, the entire unit is worked on. On 2019 models, the oil pump is part of the balance shaft assembly and hence cannot be replaced independently of the other component. Start by removing the engine oil and also pulling out the oil filter out of the engine. The engine must be supported from above with the help of a support fixture. Subsequently, the timing chain cover needs to be taken off and all the bolts of the air compressor should be loosened while the compressor should be tied out of the way without the removal of the lines. Unbolt and take off the
Oil Pan and the oil pick up tube which is installed through two mounting bolts. Using only a screwdriver, pull the tip of the oil pump drive chain tensioner spring out from beneath the shouldered bolt and then take out the two bolts and the tensioner. Remove the chain from the oil pump sprocket, using the appropriate tool, hold the oil pump drive sprocket to remove the sprocket bolt and finally, remove the sprocket. There are pump mounting bolts which must be unscrewed and then the pump. Installation is just the reverse of the removal and great care has to be taken to replace all the gaskets with new ones and tighten the mounting bolts of the oil pump to the recommended torque. Finally, after installing the oil pan it is recommended that a new oil filter be fitted and fresh oil be put into the crankcase. Lastly, look for any oil warning light in the instrument cluster, while the vehicle is running and idle.
