Frequently asked questions

What does a radiator pressure tester kit do?
It pressurizes the cooling system through the radiator neck to check for leaks. If pressure drops, you have a leak somewhere in the radiator, cap, hoses, water pump, or heater core.

Can I refill coolant with the vacuum purge adapter?
Yes. The vacuum purge tool pulls air out of the cooling system, then refills coolant in a single pass. That eliminates burping and air pockets that cause overheating.

Does this kit fit most car brands?
The 28 piece adapter set is built to fit a wide range of radiator necks and caps used on common car, light truck, and SUV models.

Is this kit suitable for a home garage?
Yes. It is designed for both professional shops and serious home mechanics who want to diagnose cooling problems instead of guessing at parts.
