Since you’ve found the issue before your engine overheated, you may have saved yourself from expensive repairs. Here are a few reasons why your car is leaking antifreeze but not overheating:
  • The radiator cap is worn out or cracked.
  • The heater core is cracked.
  • There are holes in the radiator.
  • There are holes in the radiator hose.
Fix these issues as soon as possible, as they will likely lead to real engine trouble down the road. Head to a mechanic to get the problem diagnosed.
