The Redline Detection Jaguar Land Rover (JLR) High Pressure Diagnostic Leak Detector, mandated in 112 countries, replicates the boost load of a turbocharged or supercharged engine so the sealed integrity of the entire system can be tested with the engine safely off. This tool delivers variable pressure, high-density visual vapor through the 20 psi range to find turbo/boost leaks, charge air cooler leaks, exhaust system leaks, wind and water leaks, cab leaks, cooling system leaks, intake system leaks and more. This diagnostic leak detector can, in a single procedure, reliably detect any high-pressure leak, pinpoint its exact location, and precisely identify failing components, according to the company. This product is made in the U.S.A. and is 100-percent free of dyes and other contaminants.
