摘要： A quick connect diagnostic apparatus for the cooling system of a vehicle engine includes first, second and third temperature sensors which are configured to attach to liquid hoses which circulate cooling liquid throughout the engine, the first sensor attaching to a hose directly from the engine, the second and third sensors attaching to input and output hoses, respectively, connected to the radiator. The sensors are housed within a cuff structure which is wrapped around the hoses to detect the fluid temperatures within the hoses. Each sensor is connected to an analyzer which compares the first signal to a temperature threshold signal, compares the first signal to the second signal to generate a first difference signal which is then compared to a thermostat threshold signal, and compares the second and third signals to produce a second different signal which is compared to a radiator threshold signal. The analyzer utilizes the various difference signals and temperature signals to produce output signals indicative of the engine temperature, and the operational status of the radiator and thermostat. Output circuitry electrically coupled to the analyzer provides humanly perceptible outputs in response to the output signals from the analyzer.
