SGT SUPER GARAGE TOOLS Coolant Pressure Tester Kit 33‑pc — Vacuum Refill & Leak Detection with 23 Adapters, Metal Refill Valve

This all-in-one kit groups pressure testing, vacuum bleeding and controlled coolant refilling into one portable case, so you can diagnose and service most passenger and light-commercial cooling systems quickly. It combines a vacuum pump, pressure gauge, 23 precision adapters, hoses and a metal refill valve to work with EU, US and Japanese vehicles. The kit is designed for shop technicians and DIYers who need reliable leak detection, safer coolant handling and a way to refill systems without introducing air pockets.

How does this kit detect and locate cooling system leaks?

The included pressure gauge and vacuum pump let you pressurize or evacuate the cooling circuit to reveal leaks in caps, hoses, radiators, water pumps and gaskets. Quick visual readings and steady pressure hold times make it easy to spot drops or failures.

• Pressure gauge range 0–35 PSI for radiator and cap checks.
• Vacuum test range 0–30 inHg for system integrity and leak tracing.
• 23 precision adapters fit a wide variety of filler necks and caps.
• Color-coded adapters speed correct selection and testing.

What tools are included to vacuum-bleed and refill coolant safely?

The kit contains a vacuum pump plus a purge/refill tool with an upgraded metal valve for controlled filling and to prevent air entrapment. A probe thermometer and clear hoses help you confirm safe temperatures and monitor flow during refill.

• Vacuum purge and refill tool for air-free coolant delivery.
• Upgraded metal valve for faster, more durable refills.
• Probe thermometer to verify safe system temperature before cap removal.
• Clear, reinforced hoses and O-rings for secure, leak-free connections.

Which vehicles and components are compatible with the adapter set?

The 23-adapter assortment targets fill-necks across many makes, covering European, American and Asian brands. Adapters and a universal fitting let you adapt to radiator caps, expansion tanks and service ports on most cars and light trucks.

• Adapters listed for Mercedes-Benz, BMW, Volkswagen, Audi, Ford, GM and more.
• Includes adapters for Toyota, Honda, Nissan, Subaru, Mazda and other Japanese models.
• Universal adapter and color coding reduce guesswork when matching neck sizes.
• Custom-molded case keeps each adapter organized and protected.

How durable and serviceable is this professional-grade tool kit?

Components are made from aluminum alloy, brass, nylon and reinforced rubber for wear resistance and long service life under shop conditions. The metal valve and quality fittings are intended for repeated use during diagnostics and maintenance jobs.

• Aluminum alloy and brass fittings resist corrosion and wear.
• Nylon and rubber parts engineered for sealing and flexibility.
• Sturdy, custom-molded storage case protects tools and adapters.
• Spare O-rings and clear labeling simplify maintenance and replacement.
