When I first came across the JIFETOR Cooling System Vacuum Purge Radiator Coolant Refill Tool Kit, I was intrigued by its promise of making the often tedious task of refilling automotive coolant both efficient and precise. As someone who values keeping my vehicle in top condition, this tool kit immediately stood out as a smart investment for anyone who regularly services their own car, van, SUV, or truck cooling system.
What truly impressed me is the vacuum type coolant filling function. Unlike traditional methods that can trap air pockets and potentially cause engine damage, this pneumatic vacuum tool uses shop air to create a vacuum within the cooling system. This vacuum then pulls the coolant in smoothly, ensuring no large air pockets form. This approach not only protects engine components from warping or other damage caused by improper coolant filling but also speeds up the process significantly. Typically, it takes about 5-10 minutes to refill the coolant, which is a huge time saver compared to manual filling methods. It’s important to note that a vacuum pump is required to operate this tool, although it’s not included in the kit.
The versatility of this kit is another major plus. The universal tapered rubber adapter can fit a wide range of vehicles thanks to its adjustable diameter from 1.5 cm to 5 cm. This means I can use it on multiple vehicles without needing separate tools, which is perfect for anyone with a diverse garage or for professional mechanics handling different models. The adapter replaces the radiator cap to seal the system, allowing a secure connection to the quick coupler on the coolant refiller. This design shows thoughtful engineering aimed at making the refill process leak-proof and straightforward.
Durability and quality materials are clearly priorities in this tool kit. The plastic-covered premium brass manifold body and brass fittings offer excellent anti-corrosion properties, which is crucial given the harsh environment under the hood. The gauge included is precise, with an index range from -30 to 0 inHg (-76 to 0 cmHg), and the recommended vacuum range (-25 to -20 inHg) ensures that I know exactly when it’s the right time to add coolant. The 18-inch rubber resin hose is reinforced for strength and longevity, resisting corrosion and maintaining good air sealing under pressure. Plus, the handy 21-inch metal chain hook makes it convenient to hang the tool on the engine hood, keeping everything stable during use.
Additionally, the kit includes thoughtful accessories that enhance its usability. Two air plug styles are provided—European and American—to accommodate different shop air systems, with one pre-installed for immediate use. The 60-inch coolant filling hose and the 23-inch splash-proof bleeder hose are both transparent, allowing me to visually monitor the coolant flow and spot any impurities or bubbles. Their anti-corrosion brass fittings further add to the longevity and reliability of this kit. All components are neatly organized within a customized blow molding case, which protects the gauge and keeps everything secure during storage or transport.

Things to Consider Before Buying
Before making my purchase, I considered several important factors:
- Vehicle Type: Different cars and trucks have varying cooling system designs, so I ensured the filler fit my specific vehicle.
- Frequency of Use: If you only need it occasionally, a basic model might suffice. For regular maintenance, investing in a robust, professional-grade tool is worth it.
- Budget: Prices vary widely, so I balanced cost against features and durability.
- Storage Space: Some vacuum fillers are bulky, so I made sure I had enough space to store it.
- User Reviews: Reading about other users’ experiences helped me avoid models with common issues or poor performance.
How I Use a Cooling System Vacuum Filler
Using the vacuum filler was straightforward once I understood the steps:
- Attach the filler to the radiator or coolant reservoir.
- Create a vacuum to evacuate air from the cooling system.
- Allow the coolant to be drawn in automatically, filling the system without bubbles.
- Monitor pressure gauges if available to ensure proper vacuum levels.
- Detach the filler and replace any caps securely.
This method made refilling my cooling system cleaner, faster, and more effective.
Maintenance Tips for Longevity
To keep my vacuum filler working well, I followed a few maintenance practices:
- Clean the device after each use to prevent residue build-up.
- Store it in a dry, cool place to avoid material degradation.
- Check hoses and seals regularly for cracks or leaks.
- Replace worn parts promptly to maintain vacuum integrity.
