Are there any 2005 chevy colorado cylinder head recalls?

There are not any 2005 Chevy Colorado cylinder head recalls. That said a full head replacement will not cost You more than about 300. 200 for the parts themselves, and about 100 for labor. So if You do need to get new ones it won't break the bank. The head itself is used to close off the top of the engine during combustion. If they are not working right then You will notice that the car has issues getting power when driving or that the engine just does not run right. This will lead to further problems if left alone, so make sure You get on it when the issue comes up.
