Remove the old gasket from the top part of the pan. You may need to use a putty knife or scraper to scrape the remaining residue of the gasket from the oil Pan receiver. If you cannot scrape the entire residue from the engine, you may need to use some sort of solvent remover to help remove the paper like residue of the gasket.

Step 4 - Install New Gasket on New Oil Pan

Using the gasket adhesive, place the new gasket on the new oil pan and make sure to align the gasket correctly on the new oil pan and press it down so that the adhesive can adhere securely between the gasket and oil pan.

Step 5 - Install the New Oil Pan

Also, you should change the oil filter in your car as well. Make sure to replace the filter with one that is compatible with your car's engine.

After you have put new oil into the vehicle, place a piece of cardboard or newspaper underneath the oil pan and start the engine. Allow the engine to run for several minutes to help determine if the new oil pan is leaking. If the pan is leaking, you may need to retighten the bolts that hold the oil pan to the engine.
