M31 Vacuum Purge Coolant Refill Tool Set

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.

Overall i am pretty happy with this system. It worked well on my 2010 Nissan Rogue and refilled the system with only a minimal amount of air left to bleed (I double checked with the ‘old school’ funnel method).That said, there are a couple of things that could have further improved this for me:- This system is not set up to bleed the air out of the fill hose before opening the valve to the evacuated radiator. You bleed the system using a three-way adapter, then replace that one with the fill hose. This means you will be sucking the air from the fill hose into the system initially which is not ideal. I think this is most likely the little air I had to bleed out with the funnel after finishing the vacuum fill.I will be making an adapter so I can use the three-way to also vacuum-prefill the fill hose, but the couplings that come with the system are smaller than what I normally use, so I have to get extra parts.- The main unit was too large to fit into the overflow tank opening of my Rogue, so I had to fill the system through the radiatorOverall pretty happy with the system - it makes filling your cooling system a breeze. Just wish some of the details would be better designed, but nothing that can’t be fixed.

Works well. Locally sourced vaccum pumps cost well over $400 NZD so this pump from Amazon is good value for money.

Great tool, should have bought one years ago. Makes filling a cooling system fast, easy and without the mess!

I used this tool in a 2.0 ecoboost engine without problems and everyone knows the ecoboosts are a bit finicky.Tip: since instructions sucks be aware don't build vac in the red zone or you can blow your water pump seal.Tip 2: buy a coolant tester, they are cheap.To much water if freeze can crack your block or motor head, to much, to much antifreeze don't transfer heat leading a possible overheating and engine damage.

It saved me a bunch of work and time most of the time. I've only ran across one system it didn't work correctly on. Radiator spout was just a hair to small and wouldn't allow it to seal without popping out. Not a problem of quality of this kit

Good product

Good unit with good fittings and adaptors to help purge the air out of unvented sealed cooling systems without a radiator cap. Got the job done but wish instructions were a bit clearer.

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