Q.Should I use any type of sealant when installing this gasket?
A.No, Fel-Pro gaskets are designed to be instaled on a clean and dry surface.
Q.Why are MLS Head Gaskets being used in late model applications?
A.Multi-Later Steel is the latest development in head gasket technology. The three to five layers of stainless steel shims provide the ultimate in torque retention and supplies extra strength to support current lightweight aluminum casting designs.
Q.What are Torque-to-Yield Head Bolts?
A.Torque-to-Yield Head Bolts are tightened to their yield point by tightening the bolts to a specified torque and then tightening them an additional partial turn. This creates a more even clamping force over the entire area of the gasket.
Q.Can Torque-to-Yield Head Bolts be resued?
A.The Torque-to-Yield procedure permanently streaches the bolts into their elastic range approaching the bolts elastic limit. Reusing these bolts will likely result in either head gasket failure due to a false torque reading or the bolts may break.
Q.This gasket can be installed with either side facing up, how can I tell which way to install this head gasket?
A.FEL-PRO head gaskets have directional markings of either front, left, right, top or up to help install them correctly when the orientation is critical.
