Upgrade your Defender’s weak factory heater valve with a heavy-duty billet replacement designed for 2.2 and 2.4 TDCi models. The original plastic valve is a known weak point, often suffering from seal failure, stiffness, and poor shut-off, which can allow unwanted heat into the cab even when set to cold.
Our Billet HD Heater Control Valve is designed to solve those issues while giving your engine bay a premium upgraded look and feel. Precision made and built to last, it offers a far more durable alternative to the standard plastic unit. Manufactured from 6061 aluminium, with stainless steel internal moving parts, and stainless steel fasteners.
