Webasto DW 80 Heater Service Manual

The Webasto DW 80 is a coolant heater. On a crane or heavy vehicle it warms the engine coolant and the cab before startup, so the operator isn't climbing into a frozen machine. When it quits or runs rough, the person with the wrench in hand needs workshop-level information, not guesswork. That's what this service manual is for.

What this manual helps you do

• Check the technical data before you start testing or replacing anything.
• Trace the electrical diagrams to find a dead circuit or a bad connection.
• Troubleshoot a heater that won't start or won't stay lit, using the trouble shooting section.
• Follow the repair instructions to pull, repair and refit heater components.
• Identify the instruments and tools you'll want on the bench before you open the unit.

Who this is for

Independent repair shops and rental fleet mechanics who fix heaters in-house. Also crane service technicians and plant maintenance staff who have a DW 80 on a machine with no paperwork.
