Key Functions

• Pressure Leak Detection: By using the hand pump to pressurize the radiator or expansion tank, mechanics can identify external leaks in hoses, the radiator, or the water pump without having to run the engine.
• Blown Head Gasket Diagnosis: It helps detect internal leaks, such as a cracked block or a blown head gasket, by monitoring if the system can hold a steady pressure over time.
• Radiator Cap Testing: The set includes specialized adapters to test whether the radiator cap's relief valve is opening and closing at the correct pressure.
• Vacuum Coolant Refilling: The vacuum tool (the component with the gauge and blue hose) is used to evacuate air from the cooling system. This allows for a "bubble-free" refill, preventing airlocks that could cause the engine to overheat.
• Universal Compatibility: The wide variety of color-coded adapters allows the kit to be used on a vast range of vehicle makes and models, both domestic and import.
