Works good and no leaks the only bad part is that it comes rolled up so you need a heater gun to un fold it back to shape. I don’t use a heat gun I just very carefully installed it with out damaging it then went for a test drive and the hot coolant itself made it get back to its shape then kept driving and have to leaks so it works good especially for the price and if you need it for emergency
