Audi S3 Water Pump & Thermostat Replacement DIY (2015-2021 Audi 8V A3, S3, TT, TTS)

►On the Audi 8V A3, S3, and TT, it's as if Audi engineered the water pump and thermostat to fail. The thermostat housing is made of plastic, and the water pump is made of aluminum. Over time, the plastic of the thermostat will either crack or leak from the gasket between the two pieces. If left long enough, this causes significant cooling leaks and can cause permanent damage to your engine. Since the water pump and thermostat on the 8V Audi A3, S3, and TT are electronically monitored, when you do spring a leak, you will get a check engine light and fault code for "Coolant Insufficient Flow." If you do see this, you need to immediately address this problem as you have the potential to overheat your engine. Follow along as Aaron Davis, FCP Euro's Audi Catalog Manager, demonstrates how to replace the water pump and thermostat on this 8V S3.
