Stant 12032 Cooling System Adapter, metallic

I can confirm the adapter is made in the USA. Please reference my photographic evidence.

It doesn't fit.

Haven't used it yet. But will be testing it out soon. Hope everything works out.

I'm a professional technician, so my tools get allot of use and abuse. This worked great for almost a year. But when it fails, it fails hard. The adapter exploded and I got a bath in coolant. Luckily it wasn't hot. That said, it's great for the home user. Professionals should buy snap on or equivalent. Still worth 4 stars, because the price is right. I'm buying another one of the same to replace the one that broke.

This works perfectly with my Stant pressure tester. It's a little pricey for a single piece, but less than buying a whole assortment of adapters, 90% of which you will never use, and the effectiveness of the one you need is questionable. My pressure tester works great, is totally reliable, and will last a long time. If I get another vehicle that my current kit does not work with, I will gladly get another Stant adapter to work with it.

I finally got a chance to test this adapter and found that it works as expected. Tested on a 2012 GMC Sierra 5.3L with the tow package (Z82) which includes a heavy duty radiator.

Good quality, have used 5 times and worked good every time. I hesitated to purchase this product due to some negative feedback but my experience is positive. The material is plastic with a rubber 'O' ring for the pressure seal but so is the coolant system cap from the mfg (plastic w/'O' ring). Possibly people with the negative experience did not realize the seal is at the 'O' ring and they used too much force when using,

Product worked perfectly but I ordered new and got a used one
