a - Vehicles in general

 

The strong vibrations on the tracks place above-average demands on all screw connections.  All Important screw connections (on which the safety and service life of the vehicle depend) should therefore be checked at regular intervals and tightened if necessary.

 

All rubber protection sleeves should be checked regularly to see that they are In good condition and are correctly seated.

 

b – Engine

 

- Cooling

 

Air-cooled engines

 

The engine and engine compartment should be blown out with compressed air as often as possible. Oily patches on the engine should be carefully cleaned. The cooling fins on the cylinders and cylinder heads (these are accessible from below through the cooling air outlets) must be specially checked and cleaned if necessary to prevent the engine overheating.

 

Water-cooled engines

 

Check the coolant level regularly (refer to the Instruction Manual)

 

Note:

 

If the coolant must be topped up add VW coolant additive G 11 if possible.  This ensures that the boiling point is maintained, otherwise use water.

 

The radiator fins must not become clogged up with dust and insects. They can be cleaned using a water jet or compressed air.

 

- Fuel filters The filters in the fuel pump (only on air-cooled engines) are to be checked weekly according to the quality of the fuel and cleaned if necessary. This applies also to all filters in the fuel line between tank and carburetor. - Draining water from fuel filter (Diesel engine only) - Loosen vent screw (arrow A) - Let about 100 cm3 of fluid escape from drain plug (arrow B) - Tighten vent and drain screws again.
