Coolant Overflow Tank For 2006 Lexus GS300 & 2007-2011 GS350 – Comes With Cap & Hose, Ready To Install

This is a brand new coolant reservoir that’s ready to bolt right into your 2006 Lexus GS300 or 2007-2011 GS350.

It includes both the cap and the hose, so you’ve got everything you need in one box.

Made by Evan-Fischer, this part is a direct swap for your old cracked or leaking tank—no modifications needed.

It fits both 6-cylinder and 8-cylinder models, including the 3.0L, 3.5L, and 4.6L engines.

OE numbers like 1647031030 and Partslink LX3014106 cross-reference perfectly, so you know it’s the right fit.

It comes with a 1-year unlimited-mileage warranty, and you’re covered by a 30-day return policy if anything isn’t right.

Just a heads-up: California residents should note the Prop 65 warning regarding chemical exposure.

But overall, it’s a solid, simple fix to keep your engine running cool without the dealership prices.
