The 1990-2005 Honda Civic commonly have issues with radiator leaks due to normal operation. The leak usually starts small with the engine running slightly warmer than normal, but may/will eventually cause:

  • Coolant puddling under vehicle
  • Engine overheating
  • Unexplained coolant loss (only at first)
  • Vehicle in “limp mode”; loss of power
  • Cylinder head or head gasket failure
  • The coolant leaking can have a severe effect on your vehicle if left in disrepair. If the radiator is diagnosed as the leaky part, it will need to be replaced, or resealed if that is an option.

    Note: coolant is toxic to animals, but tastes sweet. Any coolant spills should be cleaned to protect animals and children.
