Gents As the weather turns colder I'm finding the heat in my TD4 getting less and less. This is not due to the fact that the engine temp is low, it seems a lack of air flow is the problem even when the fan is turned up to max. The pollen filter is new. Any ideas would be great cos I is freezing me teats off
 
Thermostat??
The TD4 do have a large radiator and so is a cold running engine (weather not helping i know) Do you have the FBH fitted?
 
Have you changed the anti-freeze recently?

Have you bled the cooling system?

I would check it with a cold engine at idling speed with the heater temp. selector set at maximum. It can take 3 or 4 bleeds to get all the air out.

If that doesn't fix it and you haven't changed the anti-freeze I would suggest that you flush the entire system, as there may be a blockage in the heater matrix.

Good luck,

Although maybe not the best direction, you'll find air flow is best through the face level vents and should help to keep warm.
 
Are you running the air con to keep the windows demisted?

The wife's freelander is warm as toast most of the time, but when we have the dogs in the back we have to run the aircon (little buggers insist on breathing) to keep the windows demisted, while doing this the air temperature is quite a bit lower.

Have you checked the coolant temperature with the on board diagnostics? Rover did some odd stuff to the diesel R75 to make the temperature guage show 'normal' when the engine was still cold, same engine in the freelander, maybe they did the same thing?
 
Thanks for the info gents.
The engine temp and cooling system seems fine. I do get some heat out of the heater but no volume of air even when the blower is on full. I would expect to be able to dry my hair when the fan is on full power.
 
The screen vents aren't that powerful on my wife's, but I've no idea when the pollen filter was last changed, it's on my to do list along with the other 'little jobs' the thing needs doing to it :)

How noisy is the air flow when the fan is full on? We have to turn the radio up a couple of notches when it's on full belt.
 
i hear so many issues with the TD4 warm air situation, as posted above could be a number of things to check, ive tried everything other than the thermostat and i can never get warm air, takes 20 mins on fast idle jst to get luke warm, i get sufficant warm air through the footwells but the dash vents just give out frostbite
 
Had a similar problem on mine, good air flow, but hardly warm, temp gauge showing normal, noticed coolant level a bit low, less than a litre to top up to max, huge improvement in cab air temp, not sure if the fbh is working, air blowing through the “exhaust” under front bumper when engine running, but no smoke.
Heating, demist and ventilation, the only things that let the car down.
 
With my old Disco 300Tdi I used to blank off one third of the radiator in the winter. Warmed up faster and the heater was too good. Is this worth a try in my Freelander TD4? Heater performance really suffers once outside temp falls to 2 or 3 degrees or less.
