2017-2025 Coolant Drain Tubes

Make coolant service cleaner and easier again with the Square Root Fabrication Coolant Drain Tubes, designed for 2017–current Chevrolet Silverado and GMC Sierra 2500HD and 3500HD trucks. These simple but highly effective tubes help direct coolant away from the frame and suspension when draining the cooling system, preventing the messy spills that commonly occur with the factory drain location.

On many HD trucks, draining coolant can cause fluid to run down the radiator support, frame rails, and crossmembers before it ever reaches your drain pan. These drain tubes extend the drain point outward, allowing coolant to flow directly where you want it. The result is faster, cleaner maintenance and less time spent cleaning up coolant spills.

Each tube installs easily onto the factory drain outlet with no permanent modifications required. Whether you are performing routine maintenance, replacing a radiator, or servicing the cooling system on your Duramax-equipped Silverado or Sierra HD, these drain tubes make the job significantly easier.

This is a simple upgrade that makes a big difference for both DIY truck owners and professional shops working on heavy-duty GM trucks.
