Overheating on the trails? This full aluminum radiator is a sturdy, direct-fit replacement for your 2003–2008 Suzuki LT-Z400 (also fits the Kawasaki KFX400 and Arctic Cat DVX400 from those years). Made entirely from aluminum with a vacuum-brazed core—no epoxy, so it’s durable and dissipates heat efficiently. The core size is about 11.6” x 7.8” x 1.02”, and it has a standard 1/8-27NPT drain plug. It’s built to handle rough riding and resist corrosion better than cheap copper/brass units. Bolts right in using your existing mounts and hoses, so installation is pretty straightforward if you’re comfortable with basic mechanical work. Keeps your ATV’s engine running cool during long rides, hill climbs, or muddy sessions. A solid upgrade or replacement for a cracked or leaking stock radiator. Make sure your model/year matches before ordering. Ride harder, stay cooler.
