Yes. A coolant leak can drip onto a hot engine part like the exhaust manifold or engine block, and that fluid burning off produces a distinct sharp, sweet smell, sometimes with a bit of light smoke or steam from under the hood.
Coolant is designed to circulate through hoses, the radiator, and the engine in a sealed system, so it never touches surfaces that get hot enough to burn it. A leak changes that. Once coolant escapes from a cracked hose, a loose clamp, or a failing gasket, gravity and engine vibration can carry it onto nearby hot components, and that's when you get the burning smell rather than just a sweet one. You might notice it most right after driving, when you pop the hood and the smell hits you before you even look for a puddle.
Where the leak is coming from affects how noticeable the smell is; a leak near the top of the engine, close to the exhaust manifold, tends to produce a stronger, more immediate burning odor than a leak lower down, since the exhaust manifold runs much hotter than most other engine bay components. You may also see a bit of steam or light smoke rising from the engine bay in the same spot, especially right after you shut the Jeep off and heat has nowhere to go.
This isn't a smell to shrug off, even if your temperature gauge still looks normal. A coolant leak that's small enough to smell rather than see can still add up to a real loss of fluid over time, and driving with too little coolant leads to overheating and, eventually, engine damage. Ann Arbor's cold winters also mean a coolant leak is doing double duty, protecting your engine from both overheating and freezing, so it's worth catching early either way.
If you've caught a whiff of that sweet-burning smell after a drive around Ann Arbor, it's worth having someone trace it back to the source rather than waiting to see if it happens again. Hoover Street Auto Repair works on Jeep cooling systems regularly and can pinpoint exactly where coolant is escaping and seal it up before it turns into a bigger repair.
