Draper Expert Cooling System Vacuum Refill Kit

Slash your cooling system refill times and eliminate the frustration of stubborn air-locks with the Draper Expert Cooling System Vacuum Refill Kit (CAV1). Engineered for professional workshops and experienced DIY mechanics, this vacuum-assisted refill kit transforms one of the most time-consuming jobs in automotive maintenance into a fast, clean, and reliable process.

No More Air-Locks. No More Bleeding.

Traditional cooling system refills can trap air pockets that cause overheating, poor heater performance, and lengthy bleeding procedures. The CAV1 solves this entirely. By connecting to your workshop air line, the kit creates a vacuum inside the cooling system before coolant is introduced. This negative pressure draws pre-mixed coolant smoothly and completely into the system – filling from the inside out and leaving no room for air-locks to form.

Fast, Efficient Coolant Refilling

Once the vacuum is established, simply connect the filler hose and watch pre-mixed coolant flow effortlessly into the system. No waiting, no repeated top-ups, no re-bleeding. What once took the best part of an hour can be completed in a fraction of the time – making the CAV1 an essential time-saver in any busy workshop.

Complete Kit with Everything You Need

The CAV1 comes fully equipped straight out of the box:

• A screw adaptor and integrated gauge lets you monitor vacuum pressure throughout the process for complete confidence
• 1.3 metres of clear hose provides excellent visibility of coolant flow and gives you flexible reach around the engine bay
• Four adaptors ensure compatibility across a broad range of vehicle makes and models
• A hose end filler completes the connection to your coolant supply

Everything is packed neatly into a sturdy carry case, keeping all components together and protected between uses.

Built for the Workshop, Trusted by Professionals

Part of the respected Draper Expert range, the CAV1 is built to withstand the demands of daily professional use. Whether you're servicing a single car or working through a full day's bookings, this kit delivers consistent, reliable results every time.
