• Service replacement on GM truck, SUV, and car engines
• Front seal wear on high-mileage engines

Installation Notes and Tips

Confirm engine family, model year, and seal position before installation. Inspect the crankshaft sealing surface for grooves, scoring, or debris, and clean the area thoroughly so the new seal seats evenly. Verify the seal orientation during installation to avoid leaks after startup.
