These Fram filters look like crap when you pull them out. Here is a picture comparing a brand new Fram CH-9018 with one that ran in my girlfriend’s 2005 Cobalt for almost 5,000 miles. I did not distort the used filter–this is the shape it took on while inside the car.

I found a few tools that are made specifically for this rubber Cobalt filter cap. Here are the part numbers:
- Snap-on part number A106, a socket for oil filters on GM Ecotec Engines, 1 1/4″ (32mm), 3/8″ drive
- Hazet part number 2169-32, oil filter wrench
- Lisle part number 14700 Oil Filter Wrench for GM 2.2L, Filter Wrench for GM 2.2L

I just bought one on eBay that appears to be the Lisle.
The oil filter in a Chevy Cobalt sits at the front of the engine block under a rubber cap. A hex top measures 1 1/4 inches or 31.75 mm.
I used channel lock pliers to remove the filter the first few times I changed the oil on my girlfriend’s car. The rubber top is starting to get chewed up despite my use of tape over the plier teeth.
Rest assured, a tool exists. Lisle part # 14700 Oil Filter Wrench for GM 2.2L
This 32mm, made in the USA, 3/8 inch drive socket fits the oil filter cap perfectly, and it won’t bump into the intake like your wrench or my channel lock pliers.
I also found an ACDelco filter that comes with a new, replacment rubber cap and green gasket seal for about $10 here.
