Land Rover Part Number: UTP1725 - Heater Matrix - Horizontal Pipes - RHD
UTP1725 is a heater matrix with horizontal inlet and outlet pipes designed for right-hand drive Land Rover Defender models. Fitted inside the vehicle heater unit, this coolant-to-air heat exchanger transfers heat from engine coolant into the heater airflow to warm the cabin; the horizontal pipe orientation matches the ducting and hose runs used on RHD, non-air-conditioned installations within the VIN ranges shown. Inspect the matrix regularly for leaks, corrosion or blockages - a leaking matrix can allow engine coolant into the cabin and a blocked core will reduce heating performance.

Frequently Asked Questions
UTP1725 is the heater matrix fitted inside the Defender heater unit; engine coolant flows through the core while the heater blower passes air across the fins to provide warmed air to the cabin. The horizontal pipe layout matches RHD, non-air-conditioned installations. Common fault modes are coolant leaks into the heater box and core blockages reducing heat output, so inspect for leaks or contamination and replace if faulted.
