The Neilsen CT5665 Radiator Pressure and Cooling System Tester is an essential diagnostic tool for automotive mechanics and DIY enthusiasts looking to pinpoint cooling system leaks with precision. It offers the key benefit of universal compatibility through an extensive library of 30 color-coded adapters, allowing for accurate pressure testing of radiators and caps on most popular vehicle makes. However, users should note that the vast number of adapters requires careful organization and identification to ensure the correct fit for specific cooling system necks.

Yes, the kit allows you to attach the cap to the test head to verify if it holds pressure according to its rating.
The gauge is dual-graduated, displaying both PSI and BAR for maximum compatibility with different technical standards.
If an adapter seal is damaged, it may cause false leak readings; inspect and replace the O-ring seals if they show cracking or deformation.
While the kit is universal, always verify that your specific vehicle's cooling system components are designed to be pressure-tested using standard mechanical methods.
Verify that the adapter is correctly seated and the quick-coupling is fully engaged in the locking position.
Check all connection points for leaks or ensure the pressure release valve is fully closed.
Consult your vehicle's service manual to confirm the radiator neck specifications and compare them against the adapter dimensions.
Before starting, ensure the engine is completely cool; never open a hot radiator system. Select the appropriate color-coded adapter based on your vehicle's make and model documentation. Pressurize the system slowly to avoid damaging seals. After use, perform a quick visual inspection of the adapters for any signs of wear or coolant residue. Clean the adapters with a soft cloth and store them in the included molded carry case. Keep the hand pump mechanism clean and free of debris to ensure smooth operation during future tests.
