If you’re dealing with a leaky or cracked thermostat housing on your VW Mk4 1.8T, this CNC machined aluminum kit is a solid upgrade. It includes everything you need: the cooling hose flange, coolant T-fitting, thermostat housing cover, water distribution pipe, plus all the necessary gaskets, O-rings, screws, and clips. Made from high-quality CNC aluminum, it’s stronger and more reliable than plastic OEM parts, especially under heat and pressure. Installation is straightforward—just swap out the old parts with these direct-fit replacements. Perfect for 2000-2005 Mk4 1.8T models (also compatible with 2.0L in some applications). Each piece is precisely manufactured for a secure fit, so you won’t have to worry about coolant leaks down the road. We quality-check everything before shipping, but please verify your vehicle details before ordering. Whether you’re fixing a failure or just upgrading for peace of mind, this kit delivers durability and performance without breaking the bank.
