16-21 Honda Civic Coolant Recovery Tank
Direct replacement coolant expansion tank designed for 16–21 Civic models. Hard panel construction holds coolant level stable and prevents air pockets in your cooling system. Mounts at factory attachment points—no drilling or modifications required.
Can I reuse my old coolant when I swap in the new tank?
Yes—if your current coolant is fresh and at the correct concentration, drain it into a clean container before removing the old tank. Flush the system lines first to clear any sediment, then refill with your existing coolant or fresh Honda coolant as needed.
Do I need any extra hardware to install this?
Installation uses factory mounting points, so you're working with OEM hardware already on your car. Have a drain pan, basic hand tools, and a new coolant cap gasket on hand—most kits don't include the gasket, so grab one separately.
What if the tank cracks after I install it?
Test-fit the tank dry before adding coolant to catch any shipping damage. If it fails under normal use, contact our support team with photos—we handle replacements quickly. Keep your receipt and original packaging for the claim.
