ACDelco Engine Crankshaft Seal

The ACDelco Engine Crankshaft Seal (also called a crankshaft oil seal or crank seal) keeps engine oil inside the engine where the crankshaft exits the block. It also keeps dirt, dust and debris out. This helps maintain oil pressure and prevents leaks at the front or rear main seal location.

Key Features:

• Engineered to seal the rotating crankshaft against the engine block or timing cover
• Helps prevent oil leaks, oil loss and contamination of the engine bay
• Made with sealing materials designed to resist heat, oil and wear
• Backed by ACDelco, a well-known name in OE-quality replacement parts for GM and other vehicles
• Supports reliable engine sealing when replaced during timing component, clutch or flywheel service

Replacing a worn or leaking crankshaft seal restores proper sealing and protects bearings and other internal components from oil starvation. Choose the specific part number that matches your application from the available options.
