Heater Matrix for Discovery 1 and Range Rover Classic | STC250

Replacement heater matrix for the cabin heating system on non-air-conditioned Range Rover Classic and early Discovery 1 models.
The heater matrix sits inside the heater box and transfers engine heat to warm the cabin air. Over time, the original matrix can leak or become blocked, resulting in poor heater performance or coolant loss.

Features:

Direct replacement for the original heater matrix on non-A/C models

Restores effective cabin heating and demisting

Aluminium core with plastic end tanks
