5 Signs That Your Car is Leaking Coolant


Coolant leaks are often obvious, like brightly-colored puddles where you park, but there are also some subtle symptoms to look out for. Here are the most common symptoms that your car is losing coolant.


  1. Coolant Puddles Under Your Car: If coolant leaks while your car is off, it will pool under the car rather than burn on hot components. Coolant colors vary, but they are always bright and easy to notice. Book an appointment at a local auto shop if you see blue, green, orange, or pink puddles under your car.
  2. Engine Overheating: Keep an eye on the temperature gauge on your dashboard. If it starts climbing, your car is overheating. Stop driving immediately to prevent engine damage or a catastrophic failure.
  3. Dashboard Warning Lights: Modern cars have warning systems to alert you of coolant leaks. If you see a coolant warning or check engine light on the dashboard, have it diagnosed immediately. Some cars will also show detailed warning messages on the infotainment unit.
  4. A Sweet Odor from Your Engine: Engine coolant has a distinct odor. It is slightly sweet and syrupy, making it unique from any other odor that your car produces. If you notice anything like this after the engine has been running, you can look for visible leaks and call a professional.
  5. Steam or Hissing Sounds: If you see steam coming from under your hood, or you hear hissing noises, this is a sign that the coolant is leaking and boiling off on hot engine components. This is an automotive emergency. Stop driving and book a tow to a radiator shop near you in Selden, NY.

Should You Drive Your Car if You Suspect a Coolant Leak?


It’s best to avoid driving if you think there’s a coolant leak from a faulty hose or damaged radiator.


  • Only drive to an auto shop if your dashboard temperature gauge is in the safe range. If it’s red, you need a tow.
  • If you see steam, a huge coolant puddle, or have a critical dashboard warning, book a tow.
  • Minor leaks or subtle symptoms (like a sweet odor or intermittent steam) require immediate attention, but if the dashboard temperature is good, you can drive slowly to a repair shop.


There’s a fine line between imminent failure and needing service right away. If in doubt, don’t drive. Call a trusted auto shop in Selden first before heading to see a mechanic.


Leak Fixes vs. Radiator Replacement


A coolant leak isn’t always a sign that you need a complete radiator replacement. You can follow this simple table for an idea of the most likely solution at a radiator shop near you:

Symptom Likely Cause Common Repair
Puddles under the car or a sweet smell. Loose or cracked rubber coolant hose. Replace the hose and clamps. An affordable, routine fix.
Steam coming from the hood while driving. Leak in the radiator core. A full radiator replacement is the best repair. Patches are temporary and commonly fail.
Car overheating but the radiator isn’t leaking or steaming. Thermostat issue. Thermostat replacement to keep the cooling system working.
Dark colored coolant leaks The coolant is contaminated with corrosion or sludge. Potential replacement. Flushing the radiator is unlikely to restore cooling performance.
