The pressure range for the radiator tester is 0-30 cmHG and for the water tank pressure gauge is 0-35 PSI, which should be sufficient for most cooling system tests and refills. The build quality is enhanced by the upgraded metal connections on the vacuum refiller, providing better stability and suction. This should translate to more reliable performance during use.

One of the standout features is the color-coded caps, which make it easy to identify and select the appropriate cap, reducing the time and confusion often associated with such tasks. The inclusion of a custom blow-molded plastic box is a significant advantage, as it keeps all parts organized and protects delicate components like pressure gauges from damage.
