Honda EK Civic Coolant Overflow Reservoir – 19101-P2A-000
This Honda EK Civic coolant reservoir (19101-P2A-000) is the factory-fit Honda Civic coolant overflow tank for any 1996–2000 Honda Civic. Hatch, sedan, coupe, or the Si — it all uses this same EK Civic 19101-P2A-000 reservoir. It drops into the stock location and hooks up to the original hose and bracket like your old tank did when it was new.
This Honda EK coolant expansion tank catches overflow when the system gets hot, then pulls it back in as things cool, so your coolant level stays where it should and your temps stay stable. Old tanks on these cars usually yellow, crack, or seep around the seams — swapping to this Genuine Honda coolant reservoir cleans up the bay and fixes annoying leaks without any custom work. Every mount and hose connection lines up like stock.
