    What should be done after removing the Water Pump for the 2018 Chevrolet Malibu? Posted by Hassel A.
    A:
    Clean the old gasket seal from the mounting surfaces and clean the mounting bolt threads and threaded holes. Compare the replacement pump with the old one. Use a new gasket during installation, finger-tighten the mounting bolts, and then tighten them to the specified torque. You can Select Your Vehicle to see complete installation and repair tips.
