Dorman - OE Solutions Engine Coolant Filler Neck P/N:902-408

Give your cooling system a solid fill point again with the Dorman - OE Solutions Engine Coolant Filler Neck 902-408. This is the molded neck that provides the opening where coolant is added and where the pressure cap seats. It drops in as a direct-fit replacement for the 2007-2009 Lexus RX350 [V6-3.5L] and 2007-2009 Toyota Sienna [V6-3.5L], designed to match the original neck's fit and function on those listed applications.

• Direct replacement: built to install like the original neck on the listed applications, no modification required.
• Durable construction: molded from quality black plastic for reliable performance and long service life.
• Snap-on attachment: secures with the included snap ring; mounting hardware is included.
• Cap not included: the pressure/radiator cap is not supplied — reuse your original or source one separately.

Over years of heat cycling and vibration, an original plastic filler neck can crack or warp. Coolant seepage, drips around the fill point, or a visible crack are signs this neck may need replacing; if a failed filler neck is the cause, this Dorman unit restores a sound fill point. Each order includes one filler neck and one snap ring. Country of origin: China. Note: this part is also cataloged and labeled as an Engine Coolant Thermostat Housing.

Interchange: Manufacturer part number 902-408 (also 902408).
