Drivers have been issued a stark warning about a seemingly innocent sweet smell inside their cars – it could be a red flag for a dangerous mechanical fault. Experts reveal that this sugary scent often points to a coolant leak, which, if ignored, may lead to costly repairs or even engine failure.
Why Does My Car Smell Sweet?
The distinctive maple syrup-like odour typically comes from ethylene glycol, a key component in antifreeze. When your cooling system springs a leak, this liquid can drip onto hot engine parts, creating that telltale sweet aroma.
The Hidden Dangers
Ignoring this warning sign could result in:
- Overheating engines
- Complete breakdowns
- Potential fire hazards from leaking fluids
What Should Drivers Do?
Mechanics recommend taking immediate action if you notice this scent:
- Check your coolant levels
- Look for visible leaks under the car
- Avoid driving if the engine temperature rises
- Visit a garage for professional inspection
Early detection could save you thousands in repair bills and prevent dangerous roadside breakdowns. The RAC advises drivers to treat any unusual car smells as potential warning signs requiring prompt attention.
