Land Rover Repair: heater not working, aluminium tubes, coolant pump

Question

Answer
Hi Pam,

it sounds like the heater matrix is at fault.  If your fan is working but there is no heat, most likely its the matrix.  

LR description:

"Heater matrix
The heater matrix provides the heat source to warm the air being supplied to the distribution outlets. The heater matrix is an aluminium two pass, fin and tube heat exchanger, installed in the RH side of the casing. Two aluminium tubes attached to the heater matrix extend through the engine bulkhead to connect the heater assembly to the engine coolant system. When the engine is running, coolant is constantly circulated through the heater matrix by the engine coolant pump. On diesel models, the coolant flow is assisted by an electric pump while the FBH system is active."

Depending on your Disco model, what the problem is, how good the LR mechanics are and where you live, the costs to repair a heater matrix could start at $500.  I've seen heater core's for $150 online and labour could take 3 hours or more ($100 per hour).

I hope this helps.

Best of luck,

JohnMc
