M31 Vacuum Purge Coolant Refill Tool Set

GREAT VALUE!!! QUALITY MADE, Works exactly 💯 % as advertised! So glad I chose this one

Works fairly well although the clear hoses are inflexible and awkward to maneuver.

I was in the process of replacing my water pump on my 987 gen Boxster. I could not rent this tool or borrow from friends. I took a chance on this one and I'm glad I did. The price is amazing for the metal construction and nice box to keep things organized. I like having the 3 sleeves depending on your car, the small sleeve worked well for my Boxster. The tool is very easy to use and is attached to the filler next very securely. The vacuum gauge rotates for convenience. Tool was able to pull vacuum very quickly and with the value shut it held the vacuum for some time, great confirmation of the hoses etc replaced did not leak. The filler tube has a mesh flter and one-way valve. Overall it sucked and filled my cooling system of my Porsche Boxster without issues.

Tool worked as advertised. Mid size bushing fit right into the de gas bottle in my 2004 F150. Had to keep my compressor switch on because it took about 45 minutes to reach optimum vacuum. Hardest part was trying not to pull all of the coolant out of the red jugs of Motorcraft coolant as I refilled the system. Best part, no air left behind on refill.

Works but I don't think I needed it for a 2014 GMC Sierra. The tank is higher than the rest of the system and I still had to add fluid after I ran the engine up to temp, then let it cool. But it does work.

M31 vac purge kit i ordered my m31 kit on amazon and after reviewing alot adds first use was kind of tricky but after successfully finishing the coolant purge and refill with new thermostat job i was stoked with the over all results over 2 years the 5.7 hemi haven't climbed over the half way mark ' saved money good tool good investment

Works great, only one car it didn't fit on so far.

Venturi produces almost no vacuum

Good product I use it in a commercial workshop, but also affordable for the amateur, a must on modern vehicles.

Le produit est surement très bien, mais le vendeur ne veut pas me fournir de facture. donc une étoile.

Very simple to use, clean and quick way to check for leaks and fill system. This is another must have tool.

Well built kit. I used this for a complete coolant flush of my Audi A6. Be careful putting the adapter on the coolant tank. Overall surprisingly well made kit, worth the money.
