- Durable Construction Design: The radiator pressure test tool is provided with an alunimum pump cylinder, a 21\" rubber nylon resin hose, \u03c63\" large dial gauge and a brass fitting on the end. It is durable and solid designed.The large dial gauge with index range 0 to 35 psi (0-2.5 bar) is easy to observe. The Chrome plated quick coupler is designed with relief valve, which is easy to connect to radiator adapters quickly<\/li>
- Advanced Function: The pressure leak tester tool kit is perfect for detecting the internal and external leakage of cylinder, as well as detecting head gasket failure to find out which side is blocked or which cullinder leaks. You can avoid the issues resulted in the coolant and boiling point reduction, such as high engine temperature, low oil viscosity and other serious issues by regular checking with the tool<\/li>
- Easy Operation: It is easy to operate the water tank leakage detection tool, usually takes about 10 minutes to detect the leakage. You can select an available radiator cap and install it on the radiator opening, then operate the handpump until the pressure is up to 10-15 psi (note: not up to 35 psi). Then please notice the gauge reading, if the reading drops automatically, it means that it leaks in the radiator. The radiator system needs to be inspected and repaired if necessary<\/li>
- Necessary Accessories: The coolant tester kit includes 1* hand pump with pressure gauge, 8* anodized plastic cap adapters, 4* Chromed steel cap adapters, 1* thermometer and 1* carrying case.
