How to Replace the Gear Oil for Tiggo 3
2 Answers
Steps for replacing the gear oil of Tiggo 3: 1. Remove the gear. First, locate the position of the odometer cable on the transmission, then carefully remove the odometer cable shaft cover, and slowly pull out the plastic small gear. 2. Drain the old gear oil. Remove the transmission gear oil drain plug, completely drain the old gear oil, and then tighten the drain plug. Ensure all the old oil is drained to prevent contamination of the new gear oil. 3. Add new gear oil. Start adding gear oil from the odometer shaft hole, paying attention to the oil level not exceeding the F line. Be careful to prevent oil spillage during the process. 4. Reinstall. Carefully reinstall the removed gear, preferably following the operation manual to ensure no parts are missing.
Changing the gear oil for a Tiggo 3 by yourself is something I've personally experienced. First, park the car on a level surface and ensure the engine has cooled down for at least an hour before starting. I wore old clothes and gloves to prevent getting dirty, then crawled under the car to locate the transmission drain bolt, which is positioned towards the middle-rear of the chassis—use a 15mm wrench to loosen it. Place a clean pan underneath to catch the old oil—it was black and thick, taking about ten minutes to fully drain. Afterward, clean the drain hole and replace the gasket to prevent leaks before tightening the bolt. Locate the fill hole on the opposite side, open it, and pour in the correct manual transmission oil (e.g., GL-4 75W-90) using a funnel—the Tiggo 3 requires about 3-4 liters, so don’t overfill. Once filled, start the engine and let it idle in neutral for a few minutes to circulate the oil. Finally, check the oil level through the inspection hole to ensure it’s at the midpoint. Take your time during the process, and remember to properly dispose of the old oil by taking it to an auto repair shop or recycling center.
