Product Information
FelPro gaskets offer 100% vehicle sealing with applicationspecific materials to give you sealing solutions with the performance and durability professionals trust
From the manufacturer
Head Gaskets
For over 100 years, Fel-Pro Gaskets has been engineering and manufacturing sealing solutions designed for the real-world repair environment to help seal imperfect surfaces. As vehicles age, cylinder heads warp and pit over time resulting in gaskets losing their seal. Worn head gaskets may cause rough engine operation and loss of power, due to degrading compression seal in addition to other critical sealing areas. That’s where the Fel-Pro difference comes in.
Featuring application-specific and propriety technologies such as PermaTorque MLS with LaserWeld, our head gaskets are tested on-vehicle and validated by Fel-Pro to ensure optimal performance.

Every Part for the Repair
Fel-Pro gasket sets include every part needed for the repair unless otherwise noted
What is a Head Gasket?
One of the most critical gaskets in your engine, the head gasket is designed to seal the cylinders to ensure maximum compression and prevent coolant and engine oil from leaking into the cylinders. The head gasket withstands the stresses of the two surfaces expanding, shrinking, warping and rubbing while sealing in coolant and engine oil running through casting ports.
Signs of a Blown/Failing Head Gasket
Because the cylinder head gasket seals coolant passages, a blown or failing head gasket will allow coolant to enter the cylinders. Coolant in the cylinders can cause:
White smoke coming from tailpipe
Bubbling in radiator and coolant reservoir
Milky white coloration in oil
Engine overheating
Loss of coolant with no external signs of leakage
Oil and coolant streaming down head gasket
Loss of engine power and leakage between cylinders
Sweet smell from the exhaust or under hood area
How to Prepare Engine Surface
Before installing a new head gasket, surface conditions of the engine block and cylinder head(s) must be inspected and refinished if they are out of spec. In some cases, damaged castings may need to be replaced. Different gaskets require different surface finishes, so the surface finish must be matched to the type of gasket that is required for the application. Fel-Pro gaskets are designed specifically to accommodate the surface finish requirements for each application. To determine surface finish requirements, consult the OEM repair manual. Checking the cylinder head surface finish and flatness is an important step to take before installing a head gasket. Surface finish can be checked using a surface finish comparator or a profilometer.
Which Direction to Install a Fel-Pro Head Gasket
Some gaskets are asymmetric, and the correct orientation can be visually distinguished. Most Fel-Pro head gaskets have directional markings to help install them correctly when gasket orientation is critical to the installation. In some cases, head gaskets won’t have any directional indicators on them. In these cases, it does not matter which direction the gasket is installed. If it were crucial, it would be marked.
FRONT: The front of the engine is the end where the drive belts are located
RIGHT and LEFT: The right and left are determined from the driver's perspective
TOP or THIS SIDE UP: Gaskets should be facing you once it's installed
UP: Found on Subaru engines which have a horizontally exposed cylinders and the edge should be kept toward the top of the engine block
How to Install Fel-Pro Gaskets – Clean and Dry
Fel-Pro head gaskets are designed so no additional sealers are needed. Fel-Pro's premium materials compensate for surface imperfections and provide the proper amount of torque retention. Always consult the product instructions (where applicable) for sealing requirements prior to installation.
