With new Sierra cylinder heads, excessive white smoke coming from the tailpipe or coolant blowing out due to pressure built up in the cooling system is eliminated. This is because a functioning GMC Sierra cylinder head from AutoZone properly closes in the top of the cylinder, forming the combustion chamber. Visit your local AutoZone to learn about your options and get free engine diagnostic testing and battery charging while you shop. In addition, ask about our Loan-a-Tool program if you would like to make the installation in the comfort of your own home.
