Motorists have been alerted that a sweet, sugary smell when starting their car could indicate a coolant or antifreeze leak, potentially leading to repair bills exceeding £1,000. According to automotive expert Pete Ridley from Car Finance Saver, this aroma is often mistaken for an air freshener or spilled drink, but it may signal a serious issue under the bonnet.
Ridley emphasised the importance of early detection, stating: 'People are quick to notice when something feels or sounds off, but the smell of coolant is one of the most overlooked early warnings. And that delay in action can lead to overheating, damaged components, and engine failure, with repairs easily exceeding £1,000.'
Vehicle coolant is essential for regulating engine temperature. Even a minor leak can produce a potent, sweet smell, particularly after driving or when the car's heating is on. Ridley warned that regularly topping up coolant is a red flag: 'It's not evaporating, it's leaking, and your car's trying to tell you.'
Other signs of a coolant leak include misted-up windows, an overheating engine, and the need for frequent coolant refills. Ridley advised drivers to look for sticky residue around the coolant tank, damp areas near hoses, or a significant drop in coolant levels over time.
'Spotting a leak early could mean a £30 repair instead of a four-figure bill,' Ridley added, urging motorists to conduct quick checks to avoid costly damage.
