Radiator Hose: Testing and Inspection
The proper operation of the cooling system depends on the hoses and clamps being in good condition. Yet, these items are often taken for granted and
overlooked. When these oversights occur, roadside emergencies will follow which will lead to low customer satisfaction. These problems can be avoided
by proper physical and visual inspection of hoses and clamps. Hoses should not only be checked by means of a thorough visual inspection, but also by
squeezing each hose along its entire length. Look for these problems:
1. Sponginess: If the hose collapses too easily as you feel along its length, it indicates deterioration and that means hose should be replaced.
2. Bulging or Swelling: If you see this on the hose, it means there has been weakening under pressure, and replacement is again indicated.
3. Brittleness: If as you feel and wriggle the hose it has a feeling of brittleness, an immediate replacement is required.
