2. Checking the condition of the components of the cooling system should be carried out after the power unit has completely cooled down (at least 3 hours after the engine has stopped).
3. The procedure for checking the standing position and correcting the coolant level is given in Section 4.
4. Carefully inspect the upper and lower radiator hoses along with the smaller diameter interior heating hoses located between the power unit and the bulkhead of the engine compartment. Inspect hoses along their entire length and replace defective components if cracks, bulges or signs of aging are found. Small cracks are usually easier to see when squeezing the hose (see resist. illustration).
Note: This manual recommends replacing hoses approximately every two years, regardless of condition.
5. Check that all hoses are securely fastened to their fittings / nozzles. Coolant leaks usually show up as rusty or white streaks on surrounding surfaces. If the hoses are fixed to the fittings / pipes with twist-type clamps, it would be reasonable to replace the latter with more reliable worm or screw ones.
6. Blow out with compressed air or use a soft brush to remove old leaves, insect remains and other debris from the gaps between the radiator heat exchanger plates. Take care not to damage the soft plates of the heat exchanger and do not cut your fingers on their sharp edges.
