Engine Overheating:
If the engine temperature gauge rises into the red zone or a warning light comes on, the system might not be functioning properly.
Coolant Leaks:
Puddles or spots of coolant (usually green, orange, or pink) under the vehicle may indicate a leak in the radiator or hoses.
Strange Odor:
A sweet smell from the engine area could mean coolant is leaking, often from a cracked radiator or damaged hose.
Low Coolant Levels:
Frequently needing to top up the coolant could suggest a leak or problem within the cooling system.
Coolant in Oil:
If the engine oil appears milky or frothy, coolant may be leaking into the oil, indicating a potential head gasket failure or radiator issue.
Sluggish Heater:
If your car’s heater is blowing cold air, it could be a sign of a cooling system malfunction.
Unusual Noises:
A high-pitched whining or gurgling sound could be a sign of trapped air in the cooling system or a malfunctioning water pump.
Corrosion or Rust:
Visible rust or corrosion on the radiator, hoses, or coolant reservoir may suggest damage or wear.
If you notice any of these signs, it’s best to get your cooling system checked by a professional to avoid further damage to the engine.
