hTere are good youtube videos on how to replace the filler neck, mostly focussed on getting the old one off. The new unit slides on with ease!

Very easy to put on and holds very well. If you radiator has this and it brakes very cheap and great product would very much recommend it to others.

Taking the old one out was more of a challenge than putting the new one in. The new one went in easy and arrived quickly. 5 Star best bang for the buck

The part was an exact match for the original one and easy to install. Was for my 2008 Toyota Sienna Limited.If you haven’t checked your part in a very long time (or ever) I HIGHLY RECOMMEND that you check it ASAP!The plastic ends that were inside the hose had become so brittle that when I barely touched the part it crumbled. I got burnt on the inside of my left arm by some of the still quite hot radiator fluid shot across it. It happened when I was reaching across the battery.Also, recommend that you inspect the radiator fluid cap and hoses when checking things out. They glue the little vacuum lines to the splitter. So if you happen to have split ends on your vacuum lines you will NEED some glue to keep the lines from slipping off.You will need a large, very STRONG pair of pliers to remove the original factory hose clamps or a screwdriver or possibly a ratchet with socket depending on what may have been installed over the years.Very happy with the new part and how easy it was to install in my minivan.Update: part is still doing great 😊 Very satisfied with it.

Perfect fit for my 2007 Sienna LE 3.5L.There was a review that indicated that it did not come with the "horseshoe" shaped ring shown, mine did. This ring is the "lock" that keeps the Filler Neck attached. The "horseshoe" ring slips/snaps on after installing the new Filler Neck. Make sure the "horseshoe" ring is put on so the tabs on the ring align with the tab receivers on the Filler Neck.In reading other reviews and the difficulty in trying to remove the old broken Filler Neck, I decided to SLOWLY AND CAREFULLY saw off the old Filler Neck with various size hacksaws as the receiving part of the filler neck on the radiator is plastic and could break if it was treated too roughly. Took 15 minutes or so to saw off including removing the old "horseshoe" ring first with screwdriver from the bottom after detaching the horseshoe ring securing attachment. Sawed where the ring use to be because there is space between the old Filler Neck and the radiator neck so gives room to saw the Filler Neck without damaging the radiator neck. Once the old filler neck is sawed on both sides it will come off with gently force outward (the "O" ring in the Filler Neck is all that is holding it in place). The remainder of the old Filler Neck still on the radiator cannot be turned as it is held in a straight position by a groove in the Filler Neck and a corresponding tab on the radiator neck, but it there is no need to turn it as pulling straight out on it causes it to come out easily. Total time to remove old and install new - 20 minutes.Local Toyota dealership wanted $400 for a whole new radiator as Toyota does not sell just the Radiator Filler Neck. Even trying to get the radiator OEM online was $293, AND you would have to remove the whole radiator !! Much better solution to just replace the Filler Neck. If dealership replaced the whole radiator I can easily see why other reviews got quotes of $750 to $900 to do it.
