Fig. Fig. 3: Hoses

Radiator hoses are generally of two constructions, the preformed (molded) type, which is custom made for a particular application, and the spring-loaded type, which is made to fit several different applications. Heater hoses are all of the same general construction.

Inspect the condition of the radiator and heater hoses periodically. Early spring and at the beginning of the fall or winter, when you are performing other maintenance, are good times. Make sure the engine and cooling system are cold. Visually inspect for cracking, rotting or collapsed hoses, replace as necessary. Run your hand along the length of the hose. If a weak or swollen spot is noted when squeezing the hose wall, replace the hose.


  1. Remove the radiator cap.
  3. Open the radiator petcock to drain the coolant. To replace the bottom hose drain all the radiator coolant. If only the top hose is to be replaced drain just enough fluid to bring the level down below the level of the top hose. If the coolant is over a year old discard it.
  5. Remove the hose clamps and remove the hose.
  7. Use new hose clamps if the old ones are badly rusted or damaged. Slide the hose clamps over each end of the new hose then slide the hose over the hose connections.
  9. Position each clamp about 1 / 4 in. from the end of the hose and tighten.
  11. Close the petcock and refill with the old fluid if it is less than a year old or with a new mixture of 50/50, coolant/water.
  13. Start the engine and idle it for 15 minutes with the radiator cap off and check for leaks. Add coolant if necessary and install the radiator cap.
