02-05 Honda Civic SI Coolant Recovery Tank
Direct replacement expansion tank engineered for the SI platform. Hard panel construction designed to mount at factory locations without modification. Integrates with your existing cooling system for reliable overflow management.
Does this tank mount without drilling or cutting into the chassis?
Yes. This tank is engineered for factory mounting points on the SI — no drilling, cutting, or frame modification required. Locate the OEM bolt holes and you're set.
Will my existing radiator cap and overflow hose connect to this tank?
Factory hose routing and cap compatibility are confirmed for direct OEM fitment. If you're reusing your cap and hoses from the original tank, they'll work here.
What condition is the tank in when it arrives?
Tank ships ready to install — no prep, cleaning, or surface treatment needed before mounting. Inspect for shipping damage, then bolt it in place.
