How to Check the Radiator Fluid Level of the Smart 451

Model: Smart Smart 451 - Years 2007-2015
Part: Antifreeze coolant

In this video, you will learn how to check the radiator fluid level of the Smart 451. Open the engine compartment by releasing the two levers as shown in the video. Next, unclip the top part and remove the engine cover panel. On the right side of the engine compartment, you will find the radiator fluid reservoir, which has two markings. One indicates the minimum and maximum fluid levels. When topping up the fluid, ensure that the level is between these two values. Never perform this operation when the engine is hot, as you could burn yourself. Always do this with the engine cold.
