VTG VOGTEN Coolant Pressure Tester Kit 31pc (Blue) — 0–35 psi pump, vacuum refill tool

The VTG VOGTEN 31-piece Coolant Pressure Tester Kit is a complete blue diagnostic set that pressurizes, tests and vacuum-refills vehicle cooling systems for leak detection and accurate coolant replacement.

This all-in-one kit groups a pressure hand pump, vacuum refill tool, color-coded radiator caps and 23 adapters to fit most makes and models. Built from aluminum alloy, brass fittings, reinforced hoses and durable rubber components, the set is organized in a compact case so technicians and DIYers can quickly diagnose leaks, verify cap integrity and restore coolant without guessing which parts fit each vehicle.

How will this kit help me find a cooling system leak?

Use the pressure hand pump to apply up to 35 psi and observe the gauge for pressure loss; the kit lets you reproduce system pressure safely while the engine is cold so you can inspect hoses, connections and the radiator for seepage. The color-coded caps and adapters create a tight seal to avoid false positives from poor fittings.

• 0–35 psi (0–2.5 bar) hand pump with clear gauge for visible readings
• 17 color-coded radiator caps to match factory sizes
• 23 radiator adapters to fit domestic and import vehicles
• Reinforced hoses and O-rings to prevent test leaks

Can I vacuum-refill coolant with this set, and is it accurate?

The kit includes a brass-bodied coolant vacuum purge and refill tool with a gauge that reads from −30 to 0 inHg, letting you pull a strong vacuum to remove air and draw in fresh coolant without introducing bubbles. The recommended refill window around −25 to −20 inHg helps create a nearly bubble-free fill, improving cooling performance after service.

• Brass manifold and corrosion-resistant fittings for longevity
• Vacuum gauge calibrated in inHg for precise refill control
• Durable rubber hose resists pressure and chemical exposure
• Clear hoses let you confirm coolant flow during refill

Which vehicles and parts does this kit fit?

This VTG VOGTEN kit is designed with broad compatibility in mind: the 23 radiator adapters and 17 color-coded caps cover many OEM cap sizes and fit numerous brands from compact cars to larger sedans and SUVs. The set lists compatibility with popular manufacturers so you can assemble the correct adapter for the radiator neck or cap location before testing.

• Covers Mercedes-Benz, GM, Jeep, Toyota, Honda, BMW, Audi, VW and more
• Includes both EU and US air intake joints for varied designs
• Adapter set minimizes the need for extra fittings or improvisation
• Cap wrench and O-rings supplied for safe, accurate sealing

What components are included and how durable are they?

The 31-piece kit bundles a pressure pump, vacuum refill tool, thermometer, adapters, hoses, connectors, O-rings and a storage case — all chosen to resist corrosion and repeated garage use. Key parts use aluminum alloy, brass, nylon and reinforced rubber to hold up under pressure testing and frequent handling.

• Aluminum alloy radiator caps and fittings for light weight and corrosion resistance
• Brass manifold and durable fittings for vacuum refill longevity
• Reinforced hoses and upgraded filling valve for reliable sealing
• Storage case and user manual for organized transport and reference

Who this is for: The VTG VOGTEN 31PCS Coolant Pressure Tester Kit is aimed at automotive technicians, fleet maintenance teams and savvy DIY mechanics who service coolant systems on a range of vehicles. If you need a single portable kit for leak diagnosis, radiator cap testing and bubble-free coolant refills across multiple car brands, this set provides adapters, gauges and durable components to complete the job with fewer trips to the parts store.
