Top 10 Questions for Auto Radiator Mechanic Interview

Essential Interview Questions For Auto Radiator Mechanic

1. Explain the working principles of an automotive radiator?

The automotive radiator is a heat exchanger that helps regulate the engine temperature by transferring heat from the engine coolant to the surrounding air. It consists of a series of tubes and fins. Coolant flows through the tubes, while air is drawn through the fins by a fan or the vehicle’s movement. As the air passes over the hot tubes, it absorbs heat, which is then dissipated into the environment.

2. What are the common types of automotive radiators?

Brazed radiators

  • Consist of tubes brazed to header plates
  • Offer high strength and durability

Crimped radiators

  • Tubes are crimped into headers
  • Less expensive than brazed radiators

Copper-brass radiators

  • Made from copper tubes and brass headers
  • Excellent heat transfer properties

Plastic radiators

  • Tubes and headers made from plastic
  • Lightweight and corrosion-resistant

3. Describe the process of testing a radiator for leaks?

  • Visually inspect the radiator for any cracks or holes.
  • Submerge the radiator in a water bath and look for any bubbles or leaks.

9. Describe the different types of radiator caps and their functions?

Pressure Cap

  • Maintains pressure in the cooling system
  • Prevents coolant from boiling
  • Typically rated for 15-18 psi

Vacuum Cap

  • Maintains a vacuum in the cooling system
  • Prevents air from entering the system
  • Typically rated for 13-16 inches of vacuum

10. Explain the process of diagnosing and repairing a leaking radiator hose?
