Hi all own a 2000 LR D2 Td5 (385000 kms), I live in Viña del Mar Chile, pretty good weather (temperature from 10 ºC to 20 ºC) and I have the following symptom:
a. After I start the LR in the morning, takes about 15 minute driving to the engine to get at right temperature.
b. But the air from the central heating is cold all that time, is that normal in a 2000 car, I mean when I had 5 years old was better.
c. When the LR is normally running there is hot aire coming from the central heating.

I have high temperature problem 6 month ago, I cleaned the radiator and change the thermo, after that everything when to normal.

My guessing are:
a. The central heating radiator is full of crap.
b. There is a water sensor somewhere, and is giving me wromg lectures

Best regards,

Javier Amor

1. There is a coolant temp. sensor but it's used by the engine management it doesnt affect heating

2. at a temperature of 20 ºC, 15 minutes is too much to get to normal temp.....watch the gauge, if it stays below 1/4 then at a time it goes suddenly up to 1/2 the thermostat is good...if the gauge rises slowly and constantly untill the middle the stat is blocked opened so put a new one( happened to me that a new stat didnt last too long(especially if it's cheap "replacement part iso....") ...always use OEM thermostat

3. when the engine is hot check the pipes in the engine bay which are going into the heater matrix....if they are not evenly hot it means the matrix is clogged if they are hot but just cold air in the cabin u have a problem with the heater assemby's flaps system/servo motor which opens/closes the hot air duct...it's blocked closed and the air you get is only recirculated air cos the hot air can't come through it.... i coloured in red the relevant part

Thanks a lot Sierrafery, I think I might have a mix of problems here:

1st. The gauge goes smoothly to ¼ then up to the half of the gauge and these have been the behaviour since I change the thermostat, looks normal to me.

2nd. The hot air coming to the engine for a while and for what I saw after cleaning the radiator a the old thermostat, I think the “matrix is clogged” (I assume the radiator for the heating is blocked by small pieces, like the main radiator and the thermostat). I´ll check that out tomorrow. I that the case, how will you clean it?

By the whay:
a. Is there a difference in a D2 Td5 EGR or deEGR, what are the benefits?
b. What is “leccy instead of viscous” , CDL(fitted by me).

Thanks a lot

1. that's normal ehaviour

2. as i said at point 3 of my previous answer...check the coolant pipes which are going into the heater matrix(radiator for the heating as you named it) ...if both pipes are warm the problem is not there, it means the coolant circulates free there.... if not u have to remove it and flush it with radiator cleaner

3. a. "de-EGR" means deactivated/removed EGR, info here www.discovery2.co.uk /workshop - EGR removal
b. "leccy instead of viscous" means the viscous fan is removed and there is an electric("leccy") fan instead of it which is managed by an thermal switch...the engine doesnt have to "struggle" with that heavy viscous fan.

Great, I have the De EGR kit, I´ll try to do it during the weekend, is and noticeabke difference, about the fan, I´ll study it for the futere.

I´m trying to do some corrective then preventive maintainance, then I´ll improve it
