  • the cap fit fine, and seemed to be the same build quality ...
This rad cap caused a waterfall, water gurgling sound after replacing the radiator in my jeep grand grand cherokee, 2001, V8. After installing the Stant cap, I have not heard the sound in over 2 months now. Other than that, the cap fit fine, and seemed to be the same build quality as the Stant. Maybe you'll have better luck with this 1, but I wouldn't risk it. I think it wasn't properly venting air in my cooling loop. ... show more

  • lasted less than 4 months
The plastic lever mechanism is flimsy and broken after only being on a short while - it became impossible to close and lock the thing and wouldn't seal. Junky.
