COMPLETE 31-PIECE TOOL SET: Aikyciu's 31PCS coolant pressure tester kit includes 23 radiator adapters, a pressure testing pump with gauge, a vacuum purge & refill tool, a probe thermometer, a radiator cap wrench, EU and US air intake joints, replacement O-rings, clear hoses, and a storage case. This radiator pressure tester kit provides all the tools needed for complete cooling system testing and maintenance in one convenient set
23 ADAPTERS FOR MULTIPLE VEHICLE TYPES: With 23 different radiator adapters, this coolant pressure tester kit is compatible with many vehicle makes and models, including BMW, Ford, Opel, Fiat, VW, Porsche, Mercedes-Benz, Nissan, Peugeot, Chrysler, and more. A universal tapered adapter is included for additional fitting options, helping ensure you have the right adapter for most vehicles
PRESSURE TESTING AND VACUUM REFILL FUNCTIONS: This cooling system pressure tester kit serves two essential purposes. Use it to help locate leaks in the expansion tank, head gasket, radiator core, heater matrix, water pump, and connecting hoses. Switch to vacuum refill mode; the coolant vacuum refill kit function removes air pockets during coolant refill, effectively achieving bubble-free filling and preventing overheating issues caused by trapped air

After use, all components fit securely in the custom-molded carrying case with dedicated slots, keeping the set organized, protected, and ready for the next job
MATERIALS DESIGNED FOR REGULAR USE: Featuring an aluminum alloy pump cylinder, brass fittings, rubber hoses, and nylon components, this radiator pressure tester is constructed for regular use in home garages or professional shops. The gauge provides clear pressure readings, and the filling valve is designed to maintain a secure connection during both pressure testing and vacuum refill operations
