i cant find where the oil filter goes
oil filter on 2005 Chevrolet Cobalt
The oil filters are now a paper element that is inside a plastic filter housing. Here is a picture of what the housing and filter look like. You can see there is a large hex nut on the bottom for removing the housing.
You will have to take off the black cover over the block to get to the oil filter. You need a 15 cm socket to take off the top.
