VEMO V64-72-0002 Engine Cooling Sensor

The VEMO V64-72-0002 is a high‑performance coolant temperature sensor designed to provide accurate and reliable readings for modern internal combustion engines. Its compact, robust construction makes it an ideal choice for a wide range of vehicles, from compact cars to SUVs and light trucks.

Key Features

• Precision Measurement: Delivers highly accurate temperature data across the entire operating range of the engine coolant system.
• Wide Temperature Range: Operates effectively from -40 °C to +150 °C, ensuring reliable performance in both cold and hot climates.
• Durable Construction: Encased in a corrosion‑resistant housing that withstands harsh automotive environments, including exposure to coolant chemicals and high temperatures.
• Fast Response Time: Quickly reacts to temperature changes, providing real‑time data for engine management systems.
• Standardized Connector: Features a 1/8" (3.175 mm) diameter threaded connection with 28 threads per inch (TPI), compatible with most OEM and aftermarket coolant lines.
• Low Power Consumption: Designed to operate within the electrical specifications of modern engine control units, minimizing power draw.

Design & Construction Details

The sensor’s core is a platinum‑resistive element that changes resistance with temperature. This element is surrounded by a ceramic insulator and sealed within a stainless steel housing to protect against coolant ingress and mechanical shock. The threaded interface allows for secure mounting on the engine block or coolant reservoir, ensuring minimal leakage risk.

Installation Guidelines

1. Preparation: Ensure the engine is cool before installation to avoid burns. Drain a small amount of coolant if necessary to create space for the sensor.
2. Threading: Use a torque wrench set to the manufacturer’s recommended value (typically between 4–6 Nm) to secure the sensor without over‑tightening, which could damage threads.
3. Sealing: Apply a high‑temperature silicone sealant around the base of the sensor for added protection against coolant leaks.
4. Connection: Connect the sensor’s electrical lead to the engine control unit (ECU) or dedicated temperature monitoring module, following the vehicle’s wiring diagram.
5. Testing: After installation, fill the cooling system with fresh coolant and start the engine. Verify that the ECU registers a stable temperature reading within the expected range.

Compatibility Overview

The V64-72-0002 is engineered to fit seamlessly into a variety of automotive platforms, including but not limited to:

• Suzuki Samurai SUV (SJ) and Vitara models
• Subaru and Maruti variants with similar coolant system configurations
• Light-duty trucks and SUVs that require robust temperature monitoring

Its standardized thread size and universal sensor design make it a versatile component for both OEM replacements and aftermarket upgrades.
