03L121111AE Audi COOLANT TH

Coolant does a couple of really key things. It absorbs heat from the engine, that's its primary job, and then carries that heat away to the radiator where it’s released into the air. It also prevents freezing in the winter – that's where the antifreeze part comes in – and it prevents boiling in the summer. It also has corrosion inhibitors in it, which help protect all the metal parts inside your cooling system from rusting and wearing out. It’s absolutely central to keeping your engine running at the right temperature. Think of it like your engine's blood, constantly circulating to maintain a healthy internal environment. The coolant travels through passages in the engine block and cylinder head, picking up heat, then to the radiator to cool down, and back again. It works alongside the water pump, the thermostat, and the radiator to keep everything balanced. If your coolant level is low, or the coolant itself is old and degraded, your engine can overheat pretty quickly. Overheating can cause a lot of damage, from blown head gaskets to warped engine blocks. You’ll notice if things are going wrong – usually the temperature gauge will climb higher than normal, and you might see steam coming from under the hood. Maintaining the proper coolant level and replacing it at the recommended intervals—usually every few years—is a simple way to avoid a really expensive repair. You can find the correct coolant for your vehicle, and all the parts you need, over at Fixparts Online, but honestly, any reputable auto parts store will have what you need. Just be sure to use the right type for your vehicle. Smart investment: Coolant (MPN 03L121111AE) comes with a 12-month warranty!
