Review on 🔧 Universal Pro Tools: Engine Cooling System Vacuum Purge & Refill Kit Set for Effective Maintenance by Darian Massey

For the money it worked as it should. The rubber stoppers were easy to use. I had an issue that is important to note. The air compressor that the unit came with was an odd type that didn't fit my hose. As an extra no problem. The thing is, I almost broke the key trying to unscrew the fitting! The aluminum must have stuck to the fitting or something, but it took a little mapping gas, a little penetrating oil and a lot of force to get it off without breaking it or rendering it useless. Have an air fitting that you know will fit your compressor line ready before attempting to use it.
