Product Description
Radiator Reservoir (Sub-Radiator / Coolant Expansion Tank) (Mazda Genuine Part No. LFG1-15-350C).
Stores expanding coolant and returns it to the system as the engine cools, helping maintain the correct level and pressure in the cooling circuit.
You’ll typically see it on the Mazda MX-5 (NC); see our compatibility table or verify fitment using VIN/chassis.
Commonly replaced if the original tank is cracked, discoloured/brittle, leaking at seams or hose necks, or as a preventative refresh on ageing vehicles.
