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 running 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 can 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 is 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 continuing to operate the engine without enough coolant can cause serious damage.
There is a sweet smell coming from the engine compartment.
Coolant usually contains ethylene glycol, a compound with a distinctive sweet odor. If you notice this odor while your car is running or after it has stopped, you may have a coolant leak from the pipes or radiator. A small leak may not cause immediate consequences, 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 come out of 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 early warning signs of low coolant. 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 and costly repairs.
