Installation Instructions:
Step1. Clean the oil pan before installation, ensuring there is no excess oil in the surrounding area and threads.
Step2. Thread the main plug into the hole, a few threads forward and then a few back. Once the main plug bottoms out, remove it slowly and then use some brake cleaner to clean loose thread material.
Step3. Using a T-socket wrench, tighten the plug to approximately 14 ft-pounds of torque.
Step4. After installing the main plug, screw on the piggyback plug.

Note: When you need to remove little piggyback plug for oil drain, remember to use a wrench to hold the main bolt stationary.
