Yes. Sealed Power H1120CPA fits the 2005-2008 Chevrolet Cobalt 4-cylinder 2.2L, and that engine takes four pistons.
Does this Sealed Power engine piston set come with assembly lubricant?
No. Sealed Power H1120CPA does not include assembly lubricant.
Are these Sealed Power hypereutectic pistons coated?
Yes. The skirt has a DUROSHIELD coating, and the moly-graphite coating reduces friction. The piston head is flat.
What are the ring thicknesses on these Sealed Power cast pistons?
On the Sealed Power H1120CPA, the top compression ring thickness is 1.20 mm and the second compression ring thickness is 1.50 mm. The piston pin outside diameter is 20.00 mm.
Could blue smoke and oil use mean the pistons are worn?
They can, but worn rings or other engine wear can also show up this way. A shop can test compression and cylinder leakage to find the cause.
