Product Details

The Hella 007837001 is a precision-engineered temperature switch designed to control radiator fan operation in automotive cooling systems. This switch monitors engine coolant temperature and activates the cooling fan at a predetermined temperature threshold to maintain optimal engine operating conditions.

Key Features:

  • M 14 x 1.5 metric thread size for secure installation in radiator or coolant housing
  • 12-volt electrical system compatibility
  • Bimetallic disc design calibrated to snap at specific temperature for reliable switching
  • OEM-quality construction from Hella, a leading manufacturer of automotive electrical components
  • Direct replacement for multiple vehicle applications

This temperature switch uses a bimetallic disc operating principle where two metals with different thermal expansion coefficients are calibrated to activate at a specific temperature. When the coolant reaches the switch point, the disc deformation causes contact closure to trigger the cooling fan. Proper installation requires avoiding excessive tightening and bleeding air from the cooling system after replacement.
