Add coolant with confidence using the Dorman coolant filler neck (902-408), a direct-fit replacement for the 2007-2009 Lexus RX350 [V6-3.5L] and 2007-2009 Toyota Sienna [V6-3.5L]. This engine coolant filler neck provides the port where coolant is added and where the pressure cap seats and seals, keeping the cooling system closed under pressure. If the original neck has cracked or gone brittle from heat, vibration and age, this Dorman OE Solutions engine coolant filler neck restores that sealing opening.
Direct replacement: engineered to match the fit and function of the original neck on the listed applications.
Durable construction: molded from quality plastic in a black finish for reliable performance and long service life.
Snap-on installation: attaches by snap-fit and ships with a retaining snap ring (mounting hardware included).
Cap not included: transfer your existing coolant/pressure cap or source one separately.
Signs the original may need replacing include coolant seepage around the neck or a cracked, brittle housing. Country of origin: China.
