sweet syrupy smell car · antifreeze smell
A distinct sweet, syrupy odor (often compared to maple syrup) coming from the engine bay or vents, usually meaning coolant.
Check the coolant reservoir level and look under the car for a colored (usually green, orange or pink) puddle.
Not recommended for more than a very short distance. Low coolant leads quickly to overheating, which can cause serious engine damage.
