While driving my lexus rx350 home i noticed steam coming out of the top of the radiator. I stopped and noticed that the filler neck radiator was broken. Somehow. I got it home and the next day took it apart. The lexus radiator has a separate piece on the radiator filler neck that comes apart and i ordered this one on ebay and it works good. Only problem i had was putting it on the neck of the radiator so i used a little vasoline on it and a soft rubber hammer to tap it in because the tight rubber seals inside the unit would not allow me to put it on without the vasoline and soft hammer to tap it gently on. Also it has a little round plastic ring that was difficult to put on. So you have to play with that a little until it snaps into place. It holds it on the radiator neck so its very very important
