Frequently Asked Questions

Do I need a hand pump to use this tester?

Yes — you'll need a standard hand pump to pressurize a cold system. The tester itself includes the gauge and adapter; pump is sold separately.

Can I test the cooling system while the engine is running?

Yes. The unique design allows you to check for leaks and excessive pressure when the system is hot and the engine is running.

Will this fit my radiator cap?

The included 30mm adapter fits most motorcycle and ATV/UTV radiators. Check your spout diameter before ordering if your bike uses a non-standard cap.

What can I diagnose with this tester?

You can identify coolant leaks in hoses and fittings, test radiator cap pressure release limits, and determine if the radiator or cooling system is holding pressure correctly.
