Dorman 902-408 Engine Coolant Filler Neck

This product was an absolute life saver, I broke mine while changing the batteries, I literally thought I will have save the whole radiator. After watching a few YouTube videos, which lead up to this. The fit was perfect, and no leaks so far. It’s a bit tricks the remove the part but the replacement worked like a charm. Just look if it fits your car, mine was Lexus RX350 2007. You literally save hundreds of dollars and Yes it can be done as DIY project just watch a few YouTube videos and be calm. Highly recommended

Fit snug and perfect. No leaks like the other after market item I purchased on amazon. Don't waste your time buying a cheaper alternative.

Fit perfectly, googled YouTube for video on how to remove/replace on a 2011 Toyota Sienna. Just like everyone else, broke one of the nipples during battery replacement. 2 items are mildly tedious, the first is you need a pick with a hook to reach around to the bottom to grip the bottom of the "plastic C clip and dona good tug, the clip can be stubborn, but pull and it will pop off. You get a new one so I didn't worry about breaking. If piopped off in one piece on me. The 2nd part of tedious is wiggling the old neck off. I used a screw driver to wedge against the radiator support and put firm pressure on the filler neck and the wiggled the filler neck clockwise then counterclockwise. It slowly worked off. The new one input spit ;shade tree mechanic all purpose lubricant" on the o ring and it popped right on. Put the new C clip on pushing the ends to the bottom just like the original ones was. Put your two hoses back on the nipples and your radiator cap. If you forget which hose goes where, overflow tank is connected to top. Enjoy.

Amazing save. Love it. 2003 RX350 Lexus.

Part was almost identical to the factory part. I say identical because the part that held the o-ring in place was a removable ring where as the factory part was molded making a permanent grove. Part fit perfectly and installed quickly. I would definitely get a pick took to pull the c-clamp off as that made the job go very quickly (< 1 min to remove the old part). As long as the part doesn't fail we'll be good. If it fails I'll be back to update my review.

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.

Worked great! After I removed the clip prying it off with a screwdriver I tried to take old neck off but would'nt give. I could'nt get old one off, worried about breaking the radiator. I decided to heat the old one with a heat gun (try a blowdryer if you have no heat gun) then putting a screwdriver against car body and slowly prying going around as much as i can a little at a time with one hand. Then I used the other hand and pulled on it as i was prying. It then came off. Do Not twist (you may break radiator) there is a tab to align the new one so clip goes in place. Make sure you put the clip on the new one correctly, It only goes on a certain way. Hope this helps! Great product!

This was easy to install on my son’s Lexus 2008 RX350 radiator. So far over a couple months there have been no leaks. The OEM was more expensive so I took a chance that this brand would work and I needed something quickly.

Exact fit, on ne peut faire mieux!

Perfect fit in my 2007 Sienna. No more leaks.

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!

Replace my 2010 Toyota sienna broken one, works beautifully. Nobody sells it, only on Amazon, thank you, you save me around $500!

Fits like a glove
