Learn2 Flush a Car Radiator (continued)
Step 5: Inspect the clamps and the hoses

There are two radiator hoses you'll want to check. The hose at the top of the radiator carries the hot coolant away from the engine, and the hose at the bottom carries the cooled coolant back to the engine. These hoses may be on either side of the radiator, but they're always opposite each other. Don't put this off--check before you continue with the flushing. Changing the hoses requires that you drain the radiator first--so checking the hoses before you refill the radiator will prevent an unnecessary second draining.

  • Inspect the radiator hoses for leaks, cracks or soft, mushy condition. Look for signs of rust on the clamps that hold the hoses.
  • If you find one bad hose, the other hose will probably go bad in the near future. Because the coolant must be drained to replace the hoses, it makes sense to replace both at the same time. But don't actually replace the hoses until you drain the radiator.
