Pressure tester for radiator
If you have a Jeep Wrangler, 2013 or any of the JK’s for sure I’m sure lots of Dodges this tool fits. My Jeep without adapters straight out of the box. And it works perfect. I left it on for one hour, and the needle never moved. So that damn good pressure. Most impressive tool the only thing I don’t like. Is there’s no way to dump the pressure and man when you dump the radiator pressure it comes out and makes a hell of a mess so be aware of that but it was worth it!!

Great radiator pressure tester - made in USA. Very easy to use. Worked well with my 1998 Chevy Blazer LS 4 Door
In all honesty, I had not used one of these tools before and it took me a minute to get this one to line up correctly with my 1998 Chevy Blazer's radiator. I took on the task of replacing the radiator in my Blazer for the first time and I wish I would have bought one of these tools first. I test drove my blazer (made it about 10 miles) and a cooler line came loose and made a real mess and left yours truly, doing the walk of shame back home (covered in yuck) to get the tools needed to get the Blazer running again. My recommendation is to pressure test your vehicle's radiator in the driveway to save the long walk home. This tool worked very well and provided me with the confidence I needed to take my Blazer back on the road again, without fear of another cooler line coming loose and leaving me stranded or worse - ruining my engine. This tool once lined up correctly with your radiator, is very easy to use and worked well even for an inexperienced wanna be mechanic like me. The molded case for this pressure tester was very good and the documentation was adequate enough for a quick start in this device's use. The quality of workmanship for this pressure tester is excellent.

MT 300 won't fit 1998 f-150
ABSOLUTLY does NOT fit a 1998 f-150 with 4.6 There's no adapter, and having to buy the adapter is around $60 plus shipping.

Ford Mustang adapters sold separately
Does not include adapters for 2014 Ford Mustang. You need to purchase separate adapters for the Ford Mustang. One adapter has male threads for attaching the cap. Another adapter has female threads and attaches to the coolant reservoir.

Someone swapped out their old crusty one for a new one and returned it. Unfortunately, I will have to return it as well.

Great tool and well made. I only wish the hose was 6" longer for easier operation.
