What does a crankshaft seal do?

The crankshaft seal, often called a rear main seal, is located at the back of the engine where the crankshaft exits the engine block and connects to the transmission. Its main job is to prevent engine oil from leaking out of the engine.

Why is this Fel-Pro seal kit designed for repair applications?

Fel-Pro designs its seals with the repair environment in mind. This means they are often made to compensate for minor imperfections or wear on the sealing surfaces, which can be common in older engines, helping to ensure a reliable seal during a repair.

Does this kit include everything needed to replace the crankshaft seal?

This kit contains the crankshaft seal itself. It's recommended to consult your vehicle's service manual for any additional components or specialized tools that may be required for proper installation.
