Orion Motor Tech Coolant Vacuum Refill Kit — 13‑Piece Radiator Tool Set with Clear Hose & Gauge

Orion Motor Tech’s 13-piece Coolant Vacuum Refill Kit is a shop-ready tool that uses vacuum to refill and bleed vehicle cooling systems quickly and cleanly.

Save time and avoid messy, incomplete coolant fills: this kit pairs with an air compressor to evacuate air from the cooling system and draw in fresh coolant through a clear hose and filtered nozzle. Built from corrosion-resistant aluminum and brass with a shock-protected pressure gauge, the set includes multiple adapters to fit a wide range of cars and trucks so one kit can cover most garage needs.

How does this kit speed up coolant refills?

The vacuum method removes trapped air and draws coolant into the system in minutes, eliminating repeated top-offs and manual burping. Paired with an air compressor, the kit completes a refill in about 10 minutes, reducing downtime and shop labor.

• Uses an air-compressor-driven vacuum to evacuate air quickly
• Clear hose shows coolant flow so you know when the system is full
• Filtered nozzle prevents debris from entering coolant
• 13-piece set minimizes adapter swaps and setup time

Which vehicles will these adapters fit?

Orion Motor Tech included a conical adapter plus four common round adapters to cover a wide range of radiator and reservoir openings. The size range supports many passenger cars, SUVs, and light trucks so one kit can serve multiple makes and models in a mixed fleet.

• Conical adapter fits 0.3–1.8 in. openings for irregular necks
• Round adapters: 1.4, 1.5, 1.7, 2.2 in. for common fills
• Suitable for sedans, crossovers, and light-duty trucks
• Reduces need for multiple specialized refill tools

What components ensure a leak-free, reliable connection?

The kit’s fittings and control valves are crafted from corrosion-resistant aluminum alloy and brass to provide a durable, airtight seal. A robust valve layout and quality fittings reduce the risk of leaks during use and help protect your cooling system components.

• Aluminum alloy and brass fittings for corrosion resistance
• Control valves create secure, tunable vacuum flow
• Shock-resistant rubber housing for the pressure gauge
• Clear hose with secure fittings prevents spills and air ingress

How do I detect leaks and confirm a complete fill?

The included vacuum gauge reads from 0 to -30 inHg so you can verify system evacuation and quickly identify leak-prone areas. The transparent hose shows coolant movement and the filtered nozzle keeps contaminants out while you monitor the process.

• Pressure gauge in rubber housing gives clear vacuum readings
• Visible coolant flow in the clear hose confirms fill progress
• Filtered nozzle prevents debris and maintains coolant purity
• Vacuum reading helps locate leaks before reassembly or road testing

Who this kit is for: mechanics, fleet technicians, and DIY enthusiasts who perform coolant service on multiple vehicle types and want a faster, cleaner refill method. If you handle radiator flushes, coolant changes, or routine maintenance for sedans, SUVs, or light trucks, this Orion Motor Tech kit reduces fill time, improves consistency, and helps catch leaks before they turn into costly problems.
