Volkswagen Front Wheel Drive 1974-1989 Repair Guide




See Figure 1

Disconnect the radiator cooling fan when changing hoses. If the engine is warm, the cooling fan could operate even if the ignition switch is OFF.

  1. Make sure the engine is not hot, then loosen the coolant reservoir cap.

Some early models Rabbits, Dashers and Sciroccos have a petcock at the bottom of the radiator for draining purposes. Check to see if yours is equipped with one. If it is, the system can be drained without disconnecting the lower radiator hose.

  1. Place a large pan under the lower radiator hose, then loosen the clamps on the hose. Carefully disconnect it from the radiator. It makes a mess but it's the only way to drain the system on most models.
  3. Remove the clamps from the hose to be replaced, then disconnect it by cutting or twisting it to break its grip on the flange. Be careful not to damage the flange while doing so.
  5. Clean all hose connections, then slip the clamps onto the new hose.
  7. When installing the new hose, don't overtighten the clamps or the flange may become damaged. Position the hose clamps so that they are about 1 / 4 in. (6mm) from the end of the hose.
  9. After the new hose is installed and the cooling system is refilled, run the engine up to operating temperature and check for coolant leaks.
