Everything packs into a custom-molded case with color-coded fittings for quick selection. Built from aluminum alloy, brass, nylon, rubber and durable hoses, the set balances workshop toughness with shop-level organization.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the kit find leaks in different parts of the cooling system?\u003c\/h3\u003e\n\u003cp\u003eThe pressure tester lets you pressurize the cooling circuit to the cap rating so you can see where pressure drops occur. Low-pressure hold times and visible hose leaks reveal failing components such as radiator cores, heater matrices, head gaskets, and water pump seals.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003ePressure gauge for controlled test pressure up to radiator cap rating\u003c\/li\u003e\n  \u003cli\u003eAdapters seal diverse radiator necks and reservoir openings\u003c\/li\u003e\n  \u003cli\u003eHoses route test pressure to suspect zones like heater matrix or pump\u003c\/li\u003e\n  \u003cli\u003eVisible O-rings and brass fittings reduce false leaks from adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat makes refilling with the vacuum pump easier than conventional topping up?\u003c\/h3\u003e\n\u003cp\u003eThe included vacuum purge and refill tool evacuates air from the cooling system before drawing in coolant, preventing air pockets that cause hot spots or poor heat transfer.
