About the VEMO Line

VEMO is the brand line used for this replacement cooling-system switch. The VEMO V32-99-0001 follows the original-style fitment and connector layout needed for service on the listed Mazda vehicles, helping maintain proper temperature-triggered cooling fan or gauge operation where equipped.

Detailed Description

The Vemo V32-99-0001 engine coolant temperature switch is specified for 1995 Mazda 323, MX-3, and Protege models with the matching M16 x 1.5 threaded mounting point and 1-pin connector. Its 97°C switch point and 92°C reset range make it a practical replacement when the factory switch no longer responds at the correct coolant temperature. This part cross-references OE-style application numbers including N350-18-840A and N350-18840 for the same application.

What It Helps Address

• Cooling fan not switching on at the correct temperature
• Temperature-related warning or gauge irregularities
• Hard-to-diagnose overheating concerns tied to switch failure
• Intermittent cooling system control caused by worn electrical contacts
• Replacement needs after corrosion or sensor housing wear

Installation Notes and Tips

Verify the thread size, connector style, and temperature rating before installation. Confirm the mounting location on the engine or cooling passage matches the original switch, and inspect the sealing surface and gasket condition during service. For best results, compare the removed part to V32-99-0001 before final installation on the Mazda 323, MX-3, or Protege.
