VIVOHOME 110V 1/4 HP 3.5 CFM Single Stage Rotary Vane Air Vacuum Pump - Ideal for Air Conditioning, Refrigeration, and Automotive Applications

LizLiz: I will edit this if it begins working on a regular basis however I purchased this kit to pull a vacuum on my 2010 Toyota Highlander limited 3.5 L 2GRFE after I replaced the AC compressor. It worked as designed at first pulling a vacuum with no problem down to around 30 where it needed to be at to dry out the empty AC system. I ended up releasing the vacuum prematurely so when I turned it back on the fan binded in the rear of the unit and the internal breaker tripped making a click sound. Then after approximately 30 seconds you can hear it click again allowing me to try it again. It would run fairly well until you needed to shut it off for a short period of time and then it would fail again sometimes taking three or four cycles of clicking and locking up in order to restart a vacuum again. I was able to complete the project and then went to go box everything up a day later in order to return it since it was not working properly and I tried it again with no issues. I let it pull a vacuum on a capped end of the hose for about 15 minutes, shut it off and try to turn it back on again with no problems. I repeated this four more times and it did not fail again. This pump comes with the...

Des (Okanagan, BC): This kit has been a life saver for me! The value is outstanding and saved me well over $1,000 in 'professional' expenses quoted to fix my AC which wasn't properly repaired by a GM dealer to begin with. Quality components too. I've used the kit multiple times to even help friends.

DonDon: Only used it once and the oil is leaking out the shaft with the cooling fan. Two weeks past my return date with Amazon. Lesson learned.

AlbatrossAlbatross: 7/18/21-The replacement arrived in 1-day. Nice! The box was again slightly damaged, but not as bad. A small chunk of box missing on the side...

The replacement pump is great. Followed instructions for initial start as my original order. This one purrs like a kitten. Mind you, I wore ear protection for the original one because it was louder than my 3-gal air compressor.

This kit doesn't come with the valve needed to connect refrigerant can, so make sure you get one if you intend on using it right away.

I don't think this might be the 'best' pump since I'm not too confident in quality control...or maybe it's the shipper who knows. It's not like vacuum pumps are something anyone purchases too often...it'll pay itself off the first use versus going to a shop.

Also, if you are doing this because you're constantly running out of freon, I'd suggest getting a leak tester. One of those electronic halogen testers worked great for me and found leak instead of messing with UV dye, glasses and flashlight.

7/17/21- Once I followed the instructions to do an initial start, the pump made screeching/grinding noise. I immediately shut it off. It wasn't the oil...so...
