What can I do myself?

Tips for maintaining your Unimog.

When you are using your Unimog, it is constantly exposed to the environment and therefore should be regularly maintained. But this does not always require a trained expert. You can also carry out many smaller maintenance jobs yourself as part of your everyday routine.

Unimog: a service life of 25 years or more.

After every use.

  • Thoroughly remove corrosion-inducing substances with water
  • Check the frame, chassis and cab for damage to the paintwork and the corrosion protection and have it repaired immediately if necessary
  • Use contact spray on electrical contact surfaces in connectors of attached equipment and trailers

Prior to winter service operations.

  • Fit suitable chassis protection, such as a rear apron
  • Fit mud flaps to the front fenders to keep contamination of radiators from the tyres to a minimum
  • Check the antifreeze in the coolant
  • Remove dust filters or activated charcoal filters as these can clog up with snow crystals
  • Make sure not to spill any grit when loading gritting vehicles
  • Prevent the spillage of brine by ventilating the grit tank

Regularly, as required.

  • After changing equipment fully close the grommets in the rear panel of the cab
  • Clean the service brakes
  • Check that the lights are working
  • Check the condition of the tyres
  • Rinse the radiator fins with warm water
  • Apply special sealant to the engine compartment
  • Cab maintenance: wipe away damp residue immediately, vacuum off dry dust or salt residue before cleaning, including in corners and on pedals

Note: Do not use rapeseed oil, petroleum, diesel, or any substances diluted in petroleum or other solvents, for cleaning as these can damage the corrosion protection of your Unimog.
