Heater Matrix for the cabin heating system, mounted within the heater box assembly.

Engine coolant is circulated through the matrix core, and the blower fan draws air across its fins to transfer heat into the cabin. It functions as the heat exchanger for the climate control circuit, providing warm air to the demist and footwell outlets.

Frequently asked questions

What is the STC250 heater matrix and what does it do?

The STC250 heater matrix is the heat exchanger for the cabin heating system on the Land Rover Discovery 1 (1989-1998) and Range Rover Classic. Engine coolant flows through its core while the blower fan pushes air across the fins, sending warm air to the cabin, demist and footwell vents.

Where is the heater matrix located on the vehicle?

The heater matrix sits inside the heater box assembly behind the dashboard on the Discovery 1 and Range Rover Classic. It's plumbed into the engine cooling circuit, so reaching it typically means draining coolant and removing part of the heater housing under the dash.

What are the signs the heater matrix needs replacing?

Signs on the Discovery 1 and Range Rover Classic usually include coolant leaks inside the cabin, a sweet smell, fogged-up windows, or weak heat output. Internal corrosion and age typically cause the core to leak or partly block over time.

Is fitting the heater matrix a DIY job?

Fitting the heater matrix is typically an involved job on the Discovery 1 and Range Rover Classic because the heater box sits behind the dashboard. The cooling system has to be drained and the housing partly dismantled. It's doable at home with time, but many owners leave it to a workshop.
