Vacuum Coolant Refill Tool – Car Engine Cooling System Kit

Vacuum Coolant Refill & Antifreeze Replacement Tool

Keep your engine running at its best with this universal Vacuum Coolant Refill Tool. Designed for professional and home-garage use, this kit uses workshop air pressure to create a vacuum inside your vehicle's cooling system, drawing fresh coolant directly into the radiator — no air pockets, no mess, and significantly less time than traditional methods. Made in Mainland China.

Why You'll Love It

• Fast Antifreeze Replacement: The quick-connect system lets you complete a full coolant swap in a fraction of the time compared to gravity-fill methods, helping you get back on the road faster.
• Air-Free Fill: By evacuating air from the cooling system before filling, the tool effectively reduces the risk of engine overheating caused by trapped air pockets.
• Dual-Scale Pressure Gauge: The plexiglass mirror dial displays readings in both Bar (-1~0 Bar) and cmHg (-76~0 cmHg) for simple, accurate vacuum monitoring.
• Superior Sealing: Includes PVC hoses and metal joints for enhanced sealing performance, preventing leaks during the vacuum and fill process.
• Universal Fitment: Comes with 3 rubber bushes (OD 35mm, 39mm, 44mm) to fit a wide range of vehicle makes and models.
• Durable Construction: Built from ABS plastic and metal for long-lasting workshop durability.
• CE Certified: Meets CE certification standards for safety and quality assurance.

Frequently Asked Questions

Q: Is this vacuum coolant refill tool compatible with all car makes and models?

A: Yes, this tool is designed to be universal. It includes three rubber bushes in different sizes (OD 35mm, 39mm, and 44mm) to fit a wide variety of vehicle coolant reservoir necks, making it suitable for most cars, SUVs, and light trucks.

Q: Do I need a separate air compressor to use this vacuum coolant refill tool?

A: Yes, this tool uses shop/workshop air (from an air compressor) to generate the vacuum inside the cooling system. The vacuum pump included in the kit works in conjunction with a compressed air source to draw the coolant into the radiator efficiently.

Q: How does the vacuum coolant fill method help my engine?

A: By first evacuating air from the cooling system and then drawing coolant in under vacuum, this method fills the system completely without air pockets. This helps maintain optimal coolant circulation and reduces the risk of engine overheating that can occur when air gets trapped in the system.
