NO HEAT IN CABIN

Since no rise in the temp gauge, I had the thermostat changed yesterday. Even though the thermostat changed, I feel almost no difference in the temp gauge. I placed a cardboard in front of the radiator but still no quick rise as expected and no heat obviously...
Even the temp needle goes up to the midway in town traffic, still there is no heat in cabin other than warm air. So, do you have an idea what the reason is for not having adequate heat in the cabin? Would the heater core be a problem even if the temp gauge were rising up to the normal zone in town traffic or, could be air trapped in the system?

have you followed the precise Rave instructions?

did you bleed the jiggle valve?

Thank you for the links...I have just downloaded the Raves and will look into those if I am able to see what's inside.
No jiggle valve evidence on the hose leading to the heater core... Please see the picture...

The heater needs bleeding, using the bleed screw that is missing from the heater pipes However the engine should be at full running temperature within a few miles. The V6 is known for being a hot running engine, not cold. I would suggest that there's some kind of problem with the cooling system. Or someone has added a booster radiator in the circuit?
Looking at the mess of the breather pipework, anything is possible.
Oh and there's no juggle valve on the V6.

leave you header tank cap of for a couple of days while you are driving around but keep and eye on the water this according to my local garage should get any air out.

Thank you all...
I guess, previous owner's mechanic needed a jiggle valve and removed it...
First things first...I will go to "our" mechanic tomorrow and see what's gonna happen... It seems that it's not related with the thermostat that much, even if the temp gauge rises better than it does before thermostat. After the cardboard, as I mentioned, the needle rises up to the midway but, there is not enough heating in cabin because of the bad heater core for this time...
I will leave expansion tank cap off and flush the heater core this weekend depending on the mechanic's performance.

Does putting cardboard or tin foil over the radiator grill actually increase heat in some cases?
I recall seeing many cars with this during winters back in the 70's and before.

Of course it does. Especially on highway driving, it works perfectly (now, except for my Freelander).
One of my previous cars was '98 Opel Omega V6 auto and, I used to place a cardboard (actually an incandescent outer surface of a thick paper cloth bag from any company) behind the front grill in early December and remove it in mid April every year. This trick helped getting heat in cabin so much in winter time here.

If we get another cold spell I will try it as my heater is not wonderful.

It's probably the thermostat. The TD4 thermostat sticks open, stopping the engine from warming up.

I added a second stat before winter. It is much better now, but with this recent cold snap, it really struggled and took a long time to warm the cab.
Luckily, I was wearing thermal gear for work.

My TD4 has the FBH. It's job is to provide better heater output, when it's cold outside. It works too. Non FBH Freelanders had a PTC heater for extra warmth. I will say that the TD4 heater isn't as hot as then V6 heater. But that is to be expected as the TD4 runs 15°C colder than the V6.

Try flushing your heater matrix out, failing that just switch on your heated seats oh its a gaylander your proberly don't have them.

My last 3 Freelander's have had heated seats.

yeah my mates got them in his you can hardly tell their on

Mine has them to

Finally...
We have more than enough heat in cabin now...
My son took her to our new mechanic guy and, he copied all hose layout from the other Freelander in the shop with 2.5 V6 engine hose configuration. The previous owner's mechanic did his best and connected the thick heater hoses as cross-connection.
It's ok now. Tomorrow, we will change the oil and do some cleaning job, since we do not expect snow here around...

Well done thanks for letting us know
