Hold one end of the converter in place and insert a gasket between flanges, and reinstall the nuts and bolts, turning them clockwise by hand and tightening them with the ratchet and socket and a wrench.

Repeat Step 4 on the other flange and gasket. Start the car and spray both flanges with the soapy water and check for bubbles. Tighten the flange if you see bubbles.
