Shop Chevrolet Trailblazer Replacement Head Gasket

Head gaskets are the heavy metal seals that ensure your engine cylinders will be under a sufficient amount of pressure so that the air and gasoline explosions that take place within them can be channeled into powering your car. Head gaskets sit at the connection between your engine block and the cylinder head. They're made of triple-ply steel specially tempered to withstand a fluctuating range of temperature extremes. However, head gaskets do develop cracks from time to time. You can purchase a replacement head gasket for your Chevy Trailblazer online at PartsGeek.com.

When your head gasket blows, your engine block will no longer be sealed. Coolant will begin to drip out of engine channels, which can cause your engine to overheat. Since adequate pressure can no longer be maintained in your cylinders, you'll also notice engine performance problems such as misfires and rough idling.
