VEMO Engine Cooling Fan Switch Overview

The Vemo V25-99-1702 is an engine cooling fan switch for Land Rover cooling system service. It uses an M22x1.5 thread and a 2-pin connector application, with a switch point of 102°C and a switch-off range down to 93°C for temperature-controlled fan operation.

VEMO product line parts are built for OE-style replacement needs, with application-specific dimensions and connector details that matter when servicing the cooling circuit on a Land Rover Discovery, Defender 90, Defender 110, or Range Rover.

Key Features

  • Part number: V25-99-1702
  • Engine cooling fan switch for temperature-based fan control
  • Switch point: 102°C
  • Switch point to: 93°C
  • Thread size: M22x1.5

Detailed Description

This Vemo engine cooling fan switch is specified for Land Rover cooling system applications where the fan circuit must respond at a defined coolant temperature. The V25-99-1702 is listed for 1990-1998 Land Rover Range Rover, 1993 Land Rover Defender 110, 1994-1998 Land Rover Discovery, and 1994-1997 Land Rover Defender 90 applications with M22x1.5 thread size and 2-pin connector notes. The switch point of 102°C and switch-off range to 93°C support temperature-triggered fan operation in the original cooling strategy.

This part cross-references OE-style numbers such as PRC3505 and 6 037 492 for the same application. If you are searching for a Land Rover Discovery cooling fan switch, a Defender 90 engine cooling fan switch, or a Range Rover temperature switch by part number V25-99-1702, this listing matches the documented fitment and connector/thread specifications.

What It Helps Address

  • Cooling fan not switching on at the specified temperature
  • Fan cycling issues caused by a worn temperature switch
  • Incorrect coolant temperature control in the fan circuit
  • Replacement needs for damaged M22x1.5 threaded switch bodies
  • Electrical connection faults at the 2-pin fan switch interface

Installation Notes and Tips

Confirm the thread size, connector style, and temperature rating before installation. Match the existing M22x1.5 mounting point and verify the 2-pin connector layout on the vehicle harness. On Land Rover Discovery, Defender 90, Defender 110, and Range Rover cooling systems, compare the removed switch to V25-99-1702 dimensions and temperature specification before final assembly.

Quality Assurance

VEMO parts are cataloged with application-specific measurements and OE-reference data to support accurate replacement selection. Verify fitment against the vehicle’s original part number and cooling system specification before installation.
