JEGS W89733 Cooling System Pressure Tester Kit - Professional Automotive Cooling System Diagnostic Tool for Leak Detection (Includes Adapters) | Perfect for Mechanics, DIY Car Repairs & Engine Maintenance

I closed the box within one minute of opening it. The adapters were aluminum, which is great! But the pressure gauge read 3 PSI straight out of the box.I would recommend itBought it mainly for gm. Adapter does not seal properlyBought because I needed all the different adaptors but the one for BMW'S didn't thread on. Not happy. Haven't used any other adapters yet. Will update when I do.junk tried on several diff makes american, asian, european. wont seal on any of them. as a professional mechanic i bought this in an emergency to replace my snap on until i could get another, total wast of money. when i pump the air bypasses and never builds up pressureI've used this professionally for roughly a year now and it has already stopped working. The pressure pump no longer provides pressure and the plunger to the pump pulls out of the housing every time.I work at a GM dealership, I was hoping to save some money by buying this kit.... Completely worthless. No cap fits a 2000+ GM product, everything is extremely cheap and worthless. Buy a better kit and do yourself a favor. These suck.Good selection of caps are are well made.
