Radiator cap is a part which prevents leakage of cooling liquid from the expansion tank. Moreover, its valves sustain required pressure in the cooling system.

3 tips on radiator cap exploitation

  1. As the component lifetime is not specified, replace it as soon as you notice signs of wear or damaging.
  2. To make the radiator cap serve long, use only the part compatible with your car. Nominal pressure indicated on the cap should comply with the one specified in vehicle manual.
  3. Check hermiticity of a new cap with the help of a test stand, before installing it.

Defects of radiator cap, their causes and signs

  1. Deformation of a rubber seal. Usually, it occurs due to natural material ageing. As a result, the component loses the ability to maintain system pressure on the needed level. This defect can be detected during visual inspection. Leakage of anti-freeze near the cap can be an additional sign.
  2. Scratches and cracks. All these defects can break component hermeticity. They can be detected visually. If damages are significant, cooling liquid leakages can appear on the cap. Typically, these defects are the result of mechanical damage to the component or ageing of the material it is made of.
  3. Corrosion. It occurs because of moisture getting on the component. It is also detected visually.
  4. Spring flexibility loss. It occurs because of its lifetime end. A defective spring has very soft travel and it can be compressed by hand.
  5. Valves jamming. Appearance of dirt on the component may be one of the causes. The problem is easy to find during visual inspection: particularly, the defective valve may close untightly.
