Signs that your car is running out of coolant
When your car's coolant level drops, it can cause serious problems like overheating. Here are some signs to help you know when your car is low on coolant.
Engine overheating
According to Bryan Fuller, an automotive engineer at Fuller Moto (USA), when a vehicle lacks coolant, the engine will quickly heat up and may exceed safe temperature levels. If the temperature gauge on the dashboard rises rapidly or hits the red, it is a clear sign of coolant deficiency.
Temperature warning on dashboard
Most modern cars have a coolant temperature sensor. When the coolant level gets low, a “Check coolant level” warning light or message will appear. Mark Davidson, an expert at Mechanic Base (USA), emphasizes that this is a sign that should not be ignored, because the engine can be seriously damaged if it continues to operate without enough coolant.
There is a sweet smell coming from the engine compartment.
Coolant typically contains ethylene glycol, a compound with a distinctive sweet odor. If you notice this odor while driving or after stopping, you may have a coolant leak from the pipes or radiator. A small leak may not cause immediate problems, but if left untreated, it can lead to serious coolant loss.
Coolant leak under the car
If you see a green, orange, or pink puddle under your car after parking, it could be a sign of a coolant leak. The leak could be coming from the radiator, hoses, or coolant pump. Prompt inspection and repair can help prevent serious damage.
Steam or white smoke from the hood
When there is not enough coolant, the engine can overheat and cause steam or white smoke to escape from the engine compartment. This is a sign that the cooling system is no longer working properly. If you notice this, turn off the engine immediately and check the coolant level, advises David Long, a car maintenance expert at AutoBytel.
These signs are an early warning of a coolant shortage. If you notice any of these symptoms, check your coolant level immediately and top up if necessary. Also, check your cooling system for leaks and repair them. Ignoring these signs can lead to serious engine damage, resulting in costly repairs.
