It is estimated that more than 250 individual components make up the typical combustion engine used in today's cars, trucks, and SUVs. But did you know that one of the most important components are the gaskets that are installed in-between two other parts? Although they are small in size and not particularly complex, they are vital to engine function. There are a wide variety of gasket types on a typical vehicle, from head gaskets which are installed between the cylinder head and the engine block to engine gaskets which seal out harmful elements and keep the engine safe and tightly sealed. To best way to ensure that you get the correct gasket set, it is best to check the size and shape of the one currently installed so you can compare with the listed gaskets. Some important information for selecting the correct part is the type of gasket design needed (composite or metal), thickness, number of holes/ notches, bore diameter and date limitation of the unit. As car manufacturers regularly update certain peripherals and design of their models, some gasket sets will only be suitable for particular models of certain years.
