Mishimoto Coolant Pressure Tester & Vacuum Refill Kit, 28‑Piece Universal Set — Black, 35 psi Gauge

This compact, professionally oriented kit combines a precision pressure tester with a vacuum-assisted refill tool and 17 adapters to fit most domestic and import vehicles. Built for repeated garage use, the kit helps you verify radiator caps, hoses, and cooling components under controlled pressure and then restore coolant with minimal bleeding. Each component is stowed in a molded carry case so you can take the set to the vehicle or store it neatly in the shop.

How does the pressure tester reveal leaks in my cooling system?

The pressure tester pressurizes the cooling system up to approximately 35 psi, simulating operating conditions to reveal leaks at weak points, hose clamps, or cracked components. Watching for steady pressure loss or visible coolant seepage quickly pinpoints problem areas so you can plan repairs before overheating occurs. The included test caps and adapters make it possible to test either the radiator or expansion tank on most vehicles.

• Pressure range up to 35 psi for accurate leak diagnosis
• 17 adapters and 3 test caps for broad vehicle coverage
• Clear gauge for quick pressure monitoring
• Molded case keeps adapters organized for fast access

What makes the vacuum refill feature useful after repairs?

The vacuum refill tool pulls a vacuum on the cooling system to evacuate trapped air, then allows coolant to be drawn in smoothly, preventing air pockets that lead to hot spots and improper thermostat operation. This speeds up refilling and reduces the need for repeated starts-and-stops to burp the system. The process is especially valuable on vehicles with hard-to-bleed passages or elevated coolant tanks.

• Vacuum purge design minimizes airlocks during refill
• Faster, cleaner coolant top-up compared with manual bleeding
• Adapters allow vacuum refill on radiators and reservoirs
• Durable seals maintain vacuum for reliable operation

Which vehicles will the MMTL-CPT-28 fit and how do I check compatibility?

The kit includes a wide selection of adapters intended to cover most import and domestic cars and light trucks, but vehicle cooling fittings vary by make, model and year. Confirm fit by comparing the adapter profiles in the kit with your factory radiator neck or reservoir cap. If an exact match isn't obvious, measure the sealing surface diameter and consult the kit guide or Mishimoto support for compatibility help.

• 17 adapter profiles aimed at broad vehicle coverage
• Suitable for many cars, SUVs and light trucks
• Check adapter-to-neck sealing surfaces before use
• Molded case includes adapter layout for quick reference

How durable and user-friendly is the Mishimoto kit for repeated garage use?

Components are built from high-performance materials designed to withstand workshop conditions, repeated pressurization, and vacuum cycles. The carry case protects fittings and keeps components sorted so you spend less time hunting for parts. Clear markings and a straightforward setup make the kit approachable for competent DIYers while meeting the reliability expectations of professional shops.

• High-quality seals and metal connectors for longevity
• Molded storage case prevents damage during transport
• Clear gauge and labeled adapters simplify operation
• Engineered for both DIY and professional use

Who is this for: The Mishimoto MMTL-CPT-28 suits home mechanics who want professional-grade cooling system diagnostics and service, and technicians in small shops needing a portable, all-in-one pressure tester and vacuum refill solution. If you perform coolant system maintenance, repair radiators, or service vehicles with complex cooling circuits, this kit reduces guesswork and speeds accurate refills without trapped air.
