DIY Coolant Flush - Suzuki Swift Sport Track Car Build

Before turning my Suzuki Swift Sport ZC31 into a proper budget track car, it’s time to sort the basics. In this video I carry out a full coolant flush and refill on the M16A engine, making sure the cooling system is ready for harder driving and future performance upgrades. There’s no point fitting suspension, brakes and power mods if the fundamentals aren’t right — so this is part of the baseline service series on my cheapest hot hatch project. I’ll show you: How to drain the old coolant properly How to refill and bleed the system If you’ve just bought a Swift Sport, or you’re preparing one for track use, this is an essential job that’s easy to overlook. This car is going from budget daily to track-ready hot hatch — and we’re doing it properly.
