Head gaskets are built to withstand a tremendous amount of pressure and heat during their lifespans. The gaskets' job is to stop coolant and oil from leaking into the combustion chambers, while stopping exhaust gases from leaking out. But one engine overheating episode can destroy them. Gaskets can be found as connectors between engine parts. The design of gaskets can vary according to the fluids they contain, such as transmission, coolant or fuel. So, it is key that you purchase high-quality gaskets that are designed for their unique purpose. Be aware that head gaskets, when you fasten them back on the block with head bolts, must be fastened according to extremely specific torque levels, and in a specific sequence. So follow the instructions and use an accurate torque wrench to tighten the bolts. Some head bolts need to be torqued up to three times in a multiple step process. Think carefully about reinstalling used gaskets - since you are taking on this arduous task of replacing head gaskets, you certainly don't want to scrimp on this vital part!
