Stant Metallic Cooling System Adapter: Ultimate Performance for Efficient Cooling Review

At first I didn't understand that on some coolers I had to remove the rubber seals to make this seal. I rented 2 on a 2009 Honda Accord. Seems to fit.

Obviously trying to use one part number for many cars that use adjustable washers instead of springs. There are no instructions for the pucks so I almost sent them back. zero stars?

Needed to test the pressure of my cooling system on my 2013 Honda Pilot. As said, it fits. I had to remove a few spacers to fit it in the radiator as the hole is pretty narrow. But that's why they make the neck with multiple gaskets so you can remove what's needed for your car.

Good adapter. It's beautiful and durable. Just learn how to use it. There is a stack of rubber grommets in the center to help seal. If you try to use too much you can damage the radiator end tank since this adapter is made of metal (plastic is inferior to the first...). Take your time. Don't force it.

Product does not work right away. Called Stent and got their tech support. The Stant rep said to remove one (or two, if necessary) rubber washers. I did it and it works. I could have included that information in some of the instructions, either in the box or outside the box - it would have saved the frustration and call time, but it worked. The only real problem is the price. Just under $60 for a piece of aluminum is pretty expensive, but I think it's cheaper than going to a mechanic to check…

I ordered an adapter to check the coolant pressure on a 2002 Honda Civic LX 1.7L. The adapter works with both the stant pressure tester and the snap-on pressure tester. (262 episodes). The adapter did not come with instructions on how to use the adapter. To use it, what looks like a single puck (see image above) is actually 4 pucks. You will need to remove the washers one at a time until the adapter fits onto the radiator. (Tighten only by hand) The adapter worked as intended without any…

It looks very good as it has a nice appearance and finish. However, the edges that grip the radiator neck are too sharp and will cut through the plastic radiator neck. In addition, it has several washers that you can remove to adapt to different coolers, and these washers are made of rubber that is too hard to compress even after you take them off one by one while trying to get the perfect fit to find. I could use it but it damaged the heatsink and if I wasn't careful it could have cut the…
