There are all kinds of noises engines for GMC C1500 make when they have issues, but the worst one is that knocking sound that indicates you've thrown a rod. Steam pouring out from under the hood is almost as bad, since that's likely to be leaky pipes, radiator or gasket, and any of those puts your motor in danger of splitting in half. AutoZone supplies the C1500 replacement engines you need, and our Loan-a-Tool program saves you money on the parts and the repair. Take advantage of reliable advice provided by our trustworthy staff during your next in-store visit, as well as free battery charging and engine diagnostic testing.
