Ok, so sometimes when i start my car i get this whining/grinding noise straight after the engine turns over for a second or two which i have a feeling might be my starter motor. Not really sure how else to describe it. There are times where it makes the sound while trying to start the engine which slows down the starting of it. Any ideas what it might be in particular? If it is the starter motor, is there an easy way to check what part number is my starter motor as I already looked at options to get one but every seller is asking me for a part number as there are several types of starter motors for the K24a3 engine apparently.
