Your pride and joy most likely has a coolant reservoir and it probably has discoloration from the heat and impurities over the years. On top of that, the factory unit probably wasn’t all that efficient. Now S-Max is offering universal cooling reservoirs in a high polished aluminum canister. Constructed out of strong and light 6061-T6 aluminum, these coolant reservoirs feature -10AN inlet and outlets for ease of connection. The pressure-tested cap is identical to OEM coolant caps found on European vehicles. To improve your cooling system and the looks of your engine bay, the S-Max coolant reservoir is a great place to start.
