Audi Q7 Coolant reservoir replacement

Does my Audi Q7 coolant reservoir need to be replaced?

If you're driving a vehicle with an internal combustion engine you will have a coolant reservoir. This is a plastic bottle that holds some of the engine coolant which cycles through the engine, heater and radiator of your Audi Q7.

The coolant collects heat from the engine and then cools down again when it runs through the radiator. Without coolant, an engine would overheat and engine damage would occur.

Due to the nature of the engine cooling and heating up, the coolant level in the reservoir will go up and down as the Audi Q7's radiator takes in what it needs and expels what it doesn't need.

The coolant reservoir is like an overflow ready to be used when needed. The reservoir has a minimum and maximum fill level, the coolant level should be within those markers. If it is under the minimum fill level you may have a coolant leak.

Over time the plastic coolant reservoir can become brittle and form cracks and leak or get damaged while working in the Audi Q7's engine bay.

Coolant comes in different colours it could be red, green, yellow or turquoise. If you notice a fluid leak from your Audi Q7 and you suspect it's the coolant don't jump in the car and drive, further inspection is required.

If the coolant reservoir has failed you may notice the Audi Q7's temperature gauge is running hotter than normal, you might smell coolant inside or outside of the car or the coolant level in the reservoir might be below the minimum fill line or empty.

If your Audi Q7 develops a leak in the coolant reservoir, it will need to be replaced as soon as you can, and that’s where AutoGuru can help.
