This set is designed to refill radiator coolant by creating a vacuum in the cooling system, allowing coolant to be replaced without introducing air pockets. Supplied with a cone shaped adaptor to suit a variety of radiator filler necks.

• Lift vehicle / drain old coolant / replace drain plug
• Hang vacuum unit under bonnet
• Connect coolant hose and drain hose to vacuum pump (check that all valves are closed)
• Put coolant hose in coolant / make sure hose is always submerged
• Turn on vacuum switch and vacuum valve. Turn off once vacuum is created
• Turn on coolant valve. Coolant will flow into the radiator

The ET3142 is a professional-grade breakout box designed for advanced in-vehicle diagnostics and bench-top ECU testing on both 12V and 24V systems. It exposes every OBDII pin for full signal access, monitors live circuit voltages with true-RMS accuracy, and includes selectable CAN termination for controlled network testing. Its secure, high-speed interface allows safe integration of scopes, scan tools, and other diagnostic equipment, making it an essential tool for precise fault-finding, signal analysis, and ECU development work.

• Real Time VRMS Voltage Monitoring on All OBDII Pins - the integrated LCD displays true RMS voltage across all 16 pins, delivering accurate diagnostics even on fluctuating or noisy circuits. Green background highlights active dynamic signals, while immediate alerts help identify power or ground issues on critical pins (4, 5, and 16).
• Built In CAN Termination for Bench & ECU Testing - an onboard 120 ohm CAN termination switch is ideal for situations where termination is missing such as single ECU or small bench networks. This helps improve signal integrity, reduce line reflections, and stabilise communication during advanced diagnostic work.
• Intelligent Voltage Protection & Audible Alarm System - reverse polarity protection, automatic alarms for over voltage and under voltage conditions, and support for currents up to 2A, ensures that both the vehicle and diagnostic tools stay protected during testing.
