The method for changing the coolant in an Audi Q3 is: 1. Unscrew the radiator cap, open the radiator drain valve, and drain the coolant; 2. Clean the engine cooling system with clean water. During the flushing operation, keep the engine idling until clean water comes out of the radiator; 3. After the cooling system water is completely drained, close the radiator drain valve and flush the coolant reservoir; 4. Add coolant from the radiator filler port until the radiator is full, making sure not to exceed the FULL mark. Taking the 2021 Audi Q3 as an example, it is a compact SUV with the following dimensions: length 4495mm, width 1848mm, height 1616mm, wheelbase 2680mm, fuel tank capacity 60l, and trunk capacity 450l.
I often change the coolant for my Audi Q3 myself, the key is to do it when the engine is cold. First, open the hood and locate the drain plug at the bottom of the radiator, use a large basin to catch the old fluid—remember it's toxic. After the old fluid has completely drained, tighten the drain plug, then add new coolant from the expansion tank, making sure to use the OEM-approved G12 or G13 type. Fill it up to the MAX line, start the engine, and wait until the water temperature rises and the fan kicks in before turning it off. The coolant level will drop at this point, so top it up to the middle of the scale. Finally, remember to road test for five minutes and check for any leaks. Doing it yourself can save you 300 yuan in labor costs, but always wear gloves and goggles.
