8MILELAKE18pcs Radiator Pump Pressure Tester and Vacuum Pump Type Cooling System Kit

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.

Number 8 kept coming loose, I was unable to get it to drip tightly and had to abandon the test. And then the air pump fell apart. Pressure relief button came lose and the quick conect fitting leaks air. All of this on the first use im upaet I waited just a little over a month after I bought the kit to use it.

Good quality. Simple to use. Mechanic wanted 105 dollars to do the test plus cost of repairs. As I was pumping about 7 lbs saw the leak and tightened the hose clamp. End of problem.

tool works great, easy to use. Measures perfectly. though pump died early compared to other brads

Excelente herramienta. El único detalle que he tenido con ella es que a veces pierde algo de presión por la conexión de la manguera con los adaptadores.
