cox325 · Feb 10, 2013

may well do, but any reason for not changing the original thermostat?

everton · Feb 10, 2013

only reason they say its a pig of a job takes a few hours on the td4

Garboy88 · Feb 10, 2013

I've heard of somebody be4 taking the td4 thermostat out because it's in the wrong place??? And putting 1 in the top hose??? Don't know if this is correct just something somebody told me they had done

Its behind the water pump and requires the offside front wheel to be taken off to access it. I hate the placing of the damn thing!

I did this to get me through the winter months, easy to do and works well, done 5k with no issues. I got mine at euro car parts it was from a Renault 5 1.4 I believe.

job done working great temp sits at half way and heater nice and warm. very tight fit in the top hose as its slightly different on the auto td4, the thermosat is 83c for a old renault 5

Thanks for this thread and the pictures. I believe that my thermostat is stuck partially open. Its a TD4 Auto and and the heater don't work.

The heater hoses get hot, and the temp gauge sits at half way, it just been freezing all winter. Changing the stat is a four hour job, and is a bugger to do at home. So thats 4*£60 labour for a £10 stat!!!!!

Might give this a go!

Have you checked that it is bled correctly and the heater knob is opening the valve

Vertuas · Feb 17, 2013

I been bleeding the sodding thing for the past 3 years.

Freelaner · Feb 17, 2013

Heater control valve, have you checked it's operation?

also crap in the matrix ?

thats a question not an order :smokin:

hi...if you havent yet change pollen filter maybe blocking warm air in the heater . if the temp is up to half way i dont think the thermostat is the fault .

Yakko · Aug 6, 2013

Hi,

Think I'm going to do this - my TD4's temp gauge is starting to be a little less stable than previously. Although the car gets to temperature quickly enough, when you go down a long-ish hill the temp gauge quickly moves to 1/4 warm.

Don't fancy the 4 hr job to replace the factory themostat - in-line still working for you?

EDIT: Can you confirm which way round the thermostat goes in the hose?

Spacemonkey... · Oct 11, 2013

The brass tip of the thermostat should go towards the engine. I have the stat and am tempted to do the same. I have done it on other cars and it is a well known fix for certain Vauxhalls too.

Best instructions I found was:

THERMOSTAT REPLACEMENT : M47R Diesel Powered Derivatives - 75ZT Community

I know this is an old thread, but I found it while searching for info on the job so hopefully others might benefit from this answer too.

Is that the engine strip down way or get at it via the wheel arch way?

rovermgfan · Nov 19, 2013

Hi,

I have also an issue with the temp. of my Freelander td4.
Also i have a MG ZT CDTi, that had the same problem.
I resolved this with this one: Rover 75 MGZT Diesel Remote Thermostat kit - EASY FIX FOR BMW DIESEL ENGINE | eBay

Here some pics of it (not mine car) Diesel In Line Thermostat Housing " How to " - The 75 and ZT Owners Club Forums

Can some one tell of this one also fit into the Freelander?

tacr2man · Nov 19, 2013

didnt realise the 2L td4 BMW engine had a thermostat problem ? I have had to replace one thermostat for td4 in a freelander , never had problem with rover 75 cdti or other freelanders.
