Common Causes and Fixes of Antifreeze Leaks

Fixing Antifreeze Leaks

Antifreeze, also known as coolant, is important for your car. It keeps the engine running smoothly by preventing it from getting too hot or too cold. But what happens when it starts leaking? It’s a common issue, but with regular checks and maintenance, they can be prevented. Knowing the signs of a leak and the common causes can help you catch them early. If you're ever unsure about a leak or how to fix it, you can always call us to check out your vehicle. Your car's health is important for your safety on the road.


What Causes Antifreeze Leaks?

Worn Out Hoses:

  • What Happens: The hoses that carry antifreeze can become old, crack, or come loose.
  • Fix: Check hoses regularly for any signs of wear and tear. Replace them if they look damaged or worn out.


Leaky Radiator:

  • What Happens: The radiator can develop leaks due to corrosion or damage.
  • Fix: Small radiator leaks can be patched up with sealant, but for bigger leaks, you will likely need to come in or get a radiator replacement.


Faulty Water Pump:

  • What Happens: The water pump, which spreads antifreeze, can start to leak.
  • Fix: Replacing the water pump but it depends on each case.


Damaged Head Gasket:

  • What Happens: A blown head gasket can cause antifreeze to leak into the combustion chamber.
  • Fix: This is a serious issue and requires our technicians to help.

Faulty Heater Core:

  • What Happens: The heater core can start to leak antifreeze, often inside the car.
  • Fix: Heater core replacement is a complex job and may need the expertise of our technicians. 


Signs of an Antifreeze Leak

Puddles Under the Car:

  • If you see a bright green, orange, or pink liquid under your car, it's likely antifreeze.


Sweet Smell:

  • Antifreeze has a sweet smell, so if you notice this odor, check for leaks.


Overheating Engine:

  • If your car's temperature gauge is higher than usual, it might be due to low antifreeze levels.


Preventing Antifreeze Leaks

Regular Checks:

  • Regularly check the antifreeze level in your car's radiator and the condition of hoses and connections.


Routine Maintenance:

  • Regular servicing can catch potential problems before they turn into leaks.
