Perform Fluid Extraction, Refill, and Finalize

What happens here

After the hoses are connected and vacuum is initiated, allow the Mityvac fluid extractor to continuously draw the old fluid (e.g., used engine oil) from the vehicle into its internal reservoir. Monitor the fluid level in the extractor and check the vehicle's dipstick or sight glass periodically until extraction is complete. Once the old fluid is removed, the Mityvac unit, as stated by the presenter, can also be used to pump new, clean fluid back into the vehicle's appropriate fill port (e.g., oil fill cap, coolant reservoir, differential fill plug). Always ensure the correct type and quantity of new fluid are added according to the vehicle manufacturer's specifications. Properly dispose of the collected used fluid at an authorized recycling center.

Goal: Completely remove old fluid, replace it with the correct amount of new fluid, and ensure proper disposal.
