  • Did not work on my bmw x3.

    I tried the normal kseal but when it didn't work I went for the hd but unfortunately for me that didn't work too. I went to the garage before Christmas but they have been booked up, so I decided to go for kseal. I will take my car to the garage for radiator service.
