Stant Cooling System Tester, Metallic

I read a lot of reviews about the tool not sealing or feeling cheap an I would guess that they are not properly setting it up the first time. There is a hole at the top of the cylinder by the base of the shaft for the plunger, before use apply pneumatic tool oil inside. I would say about 10-15 drops actually got in, as you may need to push the plunger down as I did to suck the oil in as my bottle doesn't have a proper nozzle. Be sure to twist it around to really work it in, and you will feel when it is sealing and pressurizing the system correctly. Have used on a few vehicles so far and it works great, feels sturdy. Gets the job done for less than half of what you would pay on the tool truck. Assenmacher adapters are a must if you are testing any cooling system that isn't an old school basic radiator cap. Their website has a detailed chart of what vehicles they apply to, as be warned the Amazon descriptions aren't the most accurate.

So far it works very well. Why do they sell it as a Stant product when it is clearly marked Motorad, never the less it is beafy and feels like good quality.

One of the lowest priced cooling system pressure testers available, yet very well made of good substantial materials. The pump body is all metal - no cheap plastic. Most of what you are paying for in the more expensive kits is all the adapters. If you can use a standard "A" cap, then a simple model like this that doesn't come with a lot of adapters is all you need. It works very well and is very easy to use. You can also order from Stant any adapters you need. Stant is a very well known name in cooling system components, and the quality of this tool shows why.

Listing says Standt pressure tester, Motorad product is what arrived. Luckily, it’s a good quality product and I didn’t have time to send it back.

I used it on an older car that I own!What I like is that the price was good!

I purchased this to check the system on a Crown Victoria. The tester worked flawlessly with the adapter that I ordered separately. The quality is superb and I would highly recommend this to anyone. Testing at a shop is almost as expensive as the tester. So it's worth the price to purchase it and to be able to conduct multiple tests whenever you want. The only downside is that if you need the adapters they can add up depending on how many makes you work on. Still it's Made in the USA so you can't go wrong with American craftsmanship. In the end it is well worth the price.

First thing I noticed is the item is not a Stant tool. It is very similar but it is an off brand. (See second pic) looking at the review pics from the past it seems it was originally Stant until a few years ago then the product changed but not the listing. The second issue is the tool would not create pressure at all. I unscrewed the cylinder and it was covered in grease but the sealing cup was too small to even seal. It doesn't even touch the walls of the cylinder (see first pic, you can clearly see the gap) unfortunately for me I didn't try this tool out until way after the return date so I'm stuck with it. I was replacing my 30 year old Stant that still works the hose was just rough. Guess I can try to use the hose off of this one to fix old faithful.

if you're testing a cooling system for leaks this kit is a must and will allow to dial up the exact system pressure that you require. I suggest getting the engine warmed up slightly (but NOT to normal operating temp!) so you can simulate actual driving conditions.It may require the use of adapters to connect to your radiator or to your cap, but it fit my 2006 Sprinter without any adapters. Works really well and helped me pinpoint a number of small and annoying coolant drips that had me worried.
