Automotive diagnostic kit designed for reliable cooling system leak detection and coolant refilling. Confidence for garage technicians and keen DIY mechanics who want fewer return visits and clearer fault-finding. Is GOTLUCK Radiator Pressure Tester Kit the only cooling-system kit needed for routine workshop checks?
⚡ At a Glance
- • Leak Detection: Vacuum and pressure checking with a hand pump gauge and vacuum refill gauge for clear indication of system integrity
- • Best for: DIY mechanics and small garages performing coolant system maintenance and leak diagnosis
- • Not ideal for: Users who require a single, vehicle-specific OEM adapter only
A 28-piece professional kit that combines vacuum refill and pressure testing tools. Includes a stainless steel thermometer and a well-organised transport case for workshop use.
Accurate Leak Diagnosis – Thanks to vacuum and pressure testing instruments
A vacuum refill gauge measures from -30 to 0 inHg (-76 to 0 cmHg) and a hand pump tester registers 0-35 psi / 0-2.5 bar, both with quick disconnect fittings. Gauge movement is used to identify loss of pressure or vacuum as a sign of leakage.
Clear pass or fail readings let technicians identify leaks without trial-and-error, so pinpointing a failing head gasket or a leaking hose becomes faster and more reliable.
Faster, cleaner coolant top-ups – With the vacuum refill tool
The vacuum refill method drains air from the cooling system so coolant is drawn in by atmospheric pressure when connected to a vacuum pump. Recommended vacuum range for refill is normally around -25 to -20 inHg.
Coolant fills occur without trapped air, reducing the need for repeated bleeding and saving time during routine servicing.
Broad compatibility for most vehicles – Thanks to a 21-piece colour-coded adapter set
The kit includes 17 special adapters, one universal tapered adapter and three aluminium cap adapters, each colour-coded and matched to pictured instructions. Adapter suitability for specific vehicle models is listed in the included instructions.
A wide adapter selection avoids improvisation with ill-fitting caps and makes the kit useful for both classic and modern cars in mixed-workshop environments.

❓ Frequently Asked Questions
Q: Will the kit fit most radiator caps?
A: The kit includes 21 colour-coded adapters, including 17 special adapters, one universal tapered adapter and three aluminium cap adapters, and is described as suitable for almost all types of radiator openings on classic and modern vehicles.
Q: How does the vacuum refill tool work?
A: Connect the vacuum refill tool to a vacuum pump to drain air and form a vacuum, which then draws coolant into the cooling system; the gauge range is -30 to 0 inHg and normally -25 to -20 inHg indicates the right time to add coolant.
Q: How is a leak detected during testing?
A: Use the hand pump tester to pressurise the system and watch the pressure gauge; a drop in the gauge pointer indicates leakage, while the vacuum gauge will fail to hold vacuum if the system is not airtight.
🏆 Our Verdict
The GOTLUCK Radiator Pressure Tester Kit is well suited to DIY enthusiasts and small workshops that handle a variety of cooling systems. The combination of vacuum refill capability, a pressure hand pump with quick disconnect and a broad, colour-coded adapter set makes workshop tasks quicker and neater. Strong organisation and compatibility mean long-term utility and dependable workshop value.
