Technical Details and Specifications

Its spin-on design with a 13/16-16 thread size ensures straightforward installation on compatible GM vehicles.

Installation Notes and Tips

When installing the Wix 51045 oil filter, ensure the engine is cool to avoid burns. Apply a thin layer of clean engine oil to the filter gasket before threading it onto the engine to ensure a proper seal. Tighten the filter according to manufacturer torque specifications, typically hand-tight plus a quarter turn. Since this filter lacks an anti-drain back valve, it is important to verify oil flow during initial startup after installation.

Wix oil filters are manufactured to meet industry standards for filtration and durability. The 51045 model undergoes rigorous testing for burst pressure and flow rate to ensure consistent performance. While specific warranty details should be confirmed with the product documentation, Wix generally offers coverage against defects in materials and workmanship under normal use conditions.
