Maßgeschneiderter Auto-Silikon-Kühlerschlauch

Locate the two hoses that carry coolant between the radiator and engine. One is on the top of the radiator and the other is on the bottom of the radiator. Squeeze each Autokühlerschlauch, it should be flexible and elastic. If it feels weak, or is very hard and brittle, it needs to be replaced.

Look for signs of swelling or rupture, especially at the vulnerable bottom of the hose.

Check that the clips are holding the Maßgeschneiderter Auto-Silikon-Kühlerschlauch securely in place and are not corroded. If the clamps are corroded, they will need to be replaced.
