Hi all,
I have a 1999 Freelander 2.0DL with an L series engine. The heater reamains cold most of the time even after a 10 mile journey, especially in the colder weather of these last few days.
Last summer I did the modification to change the coolant flow pipes so that the EGR and heater matrix, etc, are effectively fed in series. I got the method from this forum and I can see this modification is well known here and often suggested to posters with heater problems.
Also last year I replaced the original thermostat housing (usual problem of broken plastic lug left the stat permanently open). I got the replacement from eBay and it has a real replaceable separate thermostat instead of the non-replaceable spring and rubber plunger arrangement as originally fitted to the car.
I can't remember the temperature stamped on the new thermostat (without removing it to look) but I think it may have been 92 degrees.
Is it likely that the problem of no heat could be corrected by replacing the new separate thermostat with a lower temp unit, say 87 or 88 degrees.If so does anyone know the part number of a suitable product from LR, QH or other supplier?
Of course I understand that the heater matrix may be blocked and that could be the problem. So far I haven't flushed this out. However, the coolant flow seems to be okay so I don't think the matrix is blocked.
Do I try to flush the matrix with a standard water hosepipe connected to one end and the other pipe open?
Your comments would be helpful as I am sick of freezing in the car on the way to/from work!
Regards,
Howard
