ET105V 16 PCS Universal Radiator Pressure Tester, Vacuum Type Cooling System Kit for Universal Vehicles,Made in Taiwan

This is a nice set and fits most vehicles and it also works great, and I don't think you can beat the price, the value to me was great. I'm really happy with this purchase.

I say intuitive because it has to be, there are no instructions. Since it is a automotive cooling system pressure tester, I expected to have to use an adapter to connect where the coolant is added to the system. I picked through the numerous adapters provided, and found one that looked like a good fit. Right the first time! It screwed right on my expansion tank. Then I looked at the pump assembly and saw it was a snap fitting, and the adapter had the matching male fitting on it, so I snapped the pump onto the adapter and started pumping away. It took awhile to get it to 1 bar, and it seems to be holding - I'm writing this review to give it a chance to bleed down and hoping it doesn't.
There are a lot of parts in the kit, all arranged nicely in a latching plastic case. I have no idea what most of the parts that are not adapters for various types and models of vehicles are, and probably will never have a reason to find out. One item is a temperature probe, somewhat similar to the one you use to see if your roast is done in the oven. Looks nice, but I don't expect to need or use it.
All in all, having owned it for about 10 minutes now, I am very satisfied with this purchase - the cheapest unit I could find on a decent car parts website was about $200 - too much for my purposes, and I could not find one to rent locally.;

Very nice setup. Worked well. I like the three valves, it allows you to isolate the system and the feed bucket. Also allows you to pre prime the tool with coolant before opening the fill line.

Worked as intended;

It worked well on my Toyota Highlander.
