WINMAX TOOLS AUTOMOTIVE
- Reduces the refill time of cooling system and prevents the air flow into the system.
- No more bleeding and save the time of clean up.
INCLUDE:
- Vacuum Coolant Refill Tool with Gauge -30~0inHg, -76~0cmHg
- 23" Transparent Bleeder Hose
- Tee Fittings for Vacuumizing
- 3x Adapter Sleeves (O.D. 45mm, 40mm & 35mm)
Vacuum Coolant Refiller
- Shockproof gauge: -30~0 inHg/-76~0 cmHg
- Equip with rubber adapter (O.D. 32MM)
- Rotate the golden rotary knob, the adapter will expand slightly to achieve a sealing effect
- Used to test leakage and replace coolant
STEPS:
- Empty the coolant as much as possible.
- Choose the right adapter sleeve to the adapter, connect the tee fittings, vacuum pump (not included), bleeder hose to the vacuum purge and refill tool.
- Insert the adapter into the radiator, and turn the golden rotary knob to seal it. Open the valve on the brass tube, and then open the vacuum pump to vacuumize till -25~-20inHg. Close the valve and vacuum pump.
- Disconnect the tee fittings, and replace by the coolant filling hose, which is inserted in the new coolant reservoir. Open the valve, and the coolant is sucked into the radiator.

Worked perfectly on 2021+ BMW reservoirs. Seal was great, vacuum held solid with no leaks. I used a cheap Amazon vacuum pump instead of an air compressor, just capped one of the fittings on the T adapter.

Fit a Japanese sedan's filler cap perfectly.This thing had a massive leak on the quick release next to the valve. I had to use a separate hand pump tool to figure this out.There was sporadic application of what looked like crazy glue to the threads that I had to remove with a brush and then add a few layers of plumbers tape and re-assemble. Otherwise, solid build quality.As it isn't stated anywhere, you will also need 90-100PSI of continual compressed air flow to generate enough of a vacuum to get to -25 hg in a system that in my case has just under 2 gallons coolant capacity. In my case I used a 6 gallon 2.6 SCFM @ 90 PSI unit.

Just used this to refill my coolant. Worked perfectly. There is a very, very slight coolant leakage around the qd fitting.. a few drops while using it.. Far from excessive.. and that could be anything. It works great, filled the car up in under 5 minutes.. Excellent for testing if you have any leaks while you still have the vacuum in the system (if vacuum drops, you have a leak.. if it doesn't you know the system is air tight).Definite;y recommend.

Held full vacuum ONE time (25 psi) then with no other changes wouldn’t hold more than 5 psi. I couldn’t even get half of the coolant needed to fill the system in before vacuum fell off completely. I confirmed there were no leaks, this tool is just a piece of trash and a complete waste of money! YOU’VE BEEN WARNED

My buddy has been preaching about how awesome these are. Snap-On will trade you a kidney for one. Why not start small? It’s a simple enough thing. First use for me was on a 2023 Blazer. Vac and filled to perfection. No leaks value is there for sure. Feels durable enough. Like I said it’s really a no brainer. The value is too good. If it breaks tomorrow I won’t be sad but it feels like a rugged enough piece. The machining on the screw feels a little crispy but it tightens down just fine. 5/5 I’ll update if something bad ever does happen.

Pros: easy to use, works well, not rocket science.Cons: second gauge was not calibrated to zero. I had to take it apart and manually zero it which is not a job I would suggest to someone who's never done it. Considering what it does on this they could have a adjustable face and do away with the faceplate on the inside of the gauge. This way you can manually turn it to 0, as you only need it for reference.This tool is kind of like being sleepy and needing a hotel to crash in before you get up bright and early to continue a road trip. You can go to the cheap hotel or you can go to the expensive hotel... When you pull the curtains and turn off the light they both get dark and you sleep equally as well. This tool cost less but gets the job done.

For the money it worked as it should. Rubber bung fittings were easy to use. The one issue I had that is important to note. The air compressor fitting the unit comes with was a strange type that didn’t fit my hose. No problem as a have extras. The issue was that I almost broke my wrench trying to unthread the fitting! The aluminum must have galled to the fitting or something, but it took a little map gas and some penetrating oil and a lot of muscle to get it off without snapping it and rendering it useless. Have a air fitting you know fits your compressor line before you attempt to use this.
