Keep Your Engine Cool in Summer and Safe in Winter

Your vehicle’s  cooling system  relies on a balanced mix of  coolant and antifreeze  to regulate engine temperature and protect against extreme conditions. Whether it’s scorching summer heat or freezing winter mornings, these fluids keep your engine from overheating or freezing — and prevent expensive damage in the process.


At Sanders Garage of Jacksonville, we provide professional  coolant and antifreeze services  that help maintain your engine’s performance and reliability all year long.

What’s the Difference Between Coolant and Antifreeze?


Though often used interchangeably, coolant and antifreeze aren’t exactly the same:


  • Antifreeze  is a concentrated chemical (typically ethylene or propylene glycol) that lowers the freezing point of your vehicle’s fluids.
  • Coolant  is a mixture of antifreeze and water — usually a 50/50 blend — that regulates both high and low engine temperatures.


Together, they circulate through the  radiator  and  engine block, transferring heat and preventing internal damage.


At Sanders Garage of Jacksonville, we check your fluid levels and refill with the right  antifreeze solution  based on your manufacturer’s specs, ensuring long-term protection.


What Happens if Your Coolant Levels Are Low?


Driving with low  car radiator coolant  or aged antifreeze can lead to serious consequences:


🔥  Engine Overheating
Excess heat can warp engine components or blow a head gasket — both costly repairs.


🛑  Corrosion and Contamination
Old or insufficient coolant allows rust and debris to build up in the system, leading to leaks or clogging.


⛽  Reduced Fuel Efficiency
An overheated engine works harder, using more fuel and reducing overall performance.


At Sanders Garage of Jacksonville, we offer  coolant refills  and  system inspections  to catch these issues early and keep your car running safely.


Common Causes of Low Coolant or Antifreeze


Low coolant doesn’t always mean you’ve forgotten a refill — it may point to a bigger problem, such as:


🔧  Leaks  – In the  radiator water pump, or  hoses
🔧 
Faulty Radiator Cap  – Causing pressure loss and fluid escape
🔧 
Cracked Radiator  – Resulting in slow coolant loss over time
🔧 
Engine Block Gasket Failure  – Letting antifreeze leak internally


Our technicians at Sanders Garage of Jacksonville will diagnose the source and recommend the right repair — whether it’s a  radiator replacement cap fix, or system reseal.


How Often Do You Need a Coolant Flush?


Over time, your  automotive coolant  degrades and loses effectiveness. That’s why most vehicles require a  coolant flush  every  30,000 miles or every 2–3 years, depending on the make and model.


A full  coolant flush  includes:


  • Draining old fluid
  • Flushing out debris or rust
  • Refilling with fresh coolant/antifreeze blend
  • Checking for leaks or damage
