TOPTUL Radiator Cap and Cooling System Pressure Test Kit with 13 Adapters

The TOPTUL JGAI1802 18PCS Universal Radiator Pressure Tester Kit helps technicians test the original radiator cap and vehicle cooling system for leaks in a practical and organised way.

The kit includes a hand pressure pump with a clear 2-1/2" pressure gauge and a protective rubber sleeve. The gauge covers a pressure range of 0–35 psi and 0–2.5 bar, with a pressure relief valve and quick coupler for easier operation during testing.

The hand pump and leakage testing adapters are made from durable Nylon 66 PA66, and the adapters are colour-coded for quick identification. The kit includes 13 radiator kits, 2 connectors, an adapter handle, and a thermometer needle, all supplied in a blow case.

This set is suitable for professional workshops looking for a radiator pressure tester kit or a car cooling system pressure tester for leak diagnosis.

What Is a Radiator Pressure Tester Kit Used For?

A radiator pressure tester kit is used to pressurise the cooling system and help detect leaks before they become more obvious during driving. It can be used to check the radiator cap, hoses, connections, radiator, and other cooling system components depending on vehicle design.

When Do You Need a Car Radiator Pressure Tester?

It is useful when coolant level drops repeatedly, the engine overheats, leak marks appear around hoses or the radiator, or after replacing cooling system parts to confirm there are no leaks.

How to Use the Kit

1. Select the correct adapter for the radiator or expansion tank opening.
2. Secure the adapter properly.
3. Connect the pressure pump using the quick coupler.
4. Increase pressure gradually according to the vehicle specification.
5. Watch the gauge for pressure drop.
6. Inspect the radiator, hoses, and connections for leaks.
7. Use the pressure relief valve before removing the tool.
