Test For Leaks In Cooling System

 Detects and exposes external system leaks

• Detects internal engine leaks due to blown gaskets or cracked block

• Vacuum type cooling system

• Purge and refill for quick change of coolant

• Test Range: 0 – 35 psi

• Includes 1 blue radiator cap test connector R123/R125

• Includes 1 black radiator cap test connector R123/R124

• Includes 1 thermometer, 1 universal radiator cap, 1 vacuum purge and refill tool, coolant hose and additional 

installation accessories

• Includes hand pump and 19 adapters (No.’s 2, 3, 4, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 19, 21, 22 and 23) to fit 

most popular domestic and import cars and trucks

 cooling system is depressurized and cool.

• Step 2: Choose the correct radiator cap for the vehicle being 

 tested from the test kit and install on cooling system opening.

• Step 3: Remove the hand pump assembly from the test kit and 

 fasten the quick coupler at the end of the hose to the radiator 

 cap securely.

 Operate the hand pump until reaching the pressure recommended by the vehicle manufacturer. (See fig. 1 & 2) DO 

 NOT exceed vehicle manufacturer’s recommended pressure or 

 maximum gauge range pressure of 35psi (2.5bar). 

• Step 4: Check the pressure reading on the gauge immediately  after reaching the vehicle manufacturer's recommended  pressure. If the pressure reading drops, there is a leak in the cooling system. After pressure testing is completed, press the release button on the quick coupler until the reading on the gauge reads 0. Remove quick coupler from radiator cap and then  remove radiator cap from the cooling system opening. Locate  the leak and repair as necessary.

• Step 2: Remove the purge and refill tool from the test kit and hang the tool in a convenient location under the hood with the hook provided.

• Step 3: Choose the correct radiator cap for the vehicle being tested, or the universal rubber radiator adapter from the test kit and install the one of your choice on the cooling system opening. Fasten the quick coupler at the end of the hose on the purge and refill tool to the radiator cap securely. (See fig. 4 & 5)

• Step 4: Turn valve No. 3 to the open position and valve No. 6 to the closed position. (See fig. 6)

• Step 5: Connect air supply to the purge and refill tool and press operating button until the pressure reaches 20-25 Hg (50-60cmHg). Turn valve No. 3 to the closed position and release the operating button. (See fig. 7 & 8)

• Step 2: Assure that valve No. 3 is in the closed position and that there is coolant in the coolant hose.
