Hi guys want to disconnect my external heater on 2005 freelander one.can I just pull a fuse out or something. Please.
 
My heating on most freelanders are not the best iv found and this being the first iv had with one of the heaters.
So why would I put up with the exhaust smoke being sucked in vi air intake so I open the window and get colder.lol
And my fuel gauge seems to be going down since its started coming on in the last couple weeks.

The heating on a Freelander isn't bad, or shouldn't be.

The fuel burning heater is there to increase the temperature of the water going to the heater while the engine is warming up, and on rare occasions when the engine doesn't make enough heat on its own due to very low outside temperatures.

Stopping this additional heating will result in an even colder heater when the engine is warming up, and much longer warm up times.

The FBH seldom blows flue gasses into the vehicle, as the output is low level and behind the front bumper, however if it's smoky, it suggests it's in need of a service.

If your FBH is running longer that a few minutes after starting, then it's indicating an issue with the engine thermostat, as the FBH only fires up when the coolant is below 75°C. A faulty thermostat will prevent the engine from reaching ithe 88°C running temperature, causing increased fuel consumption, and a lot less heat from the heater..

My suggestion is to fit an in line thermostat to the top hose which has been discussed on here many times, after which the engine will run hotter, increasing the heater output and making sure the FBH only runs when it's actually needed.
 
Heater in my 2004 TD4 comes in the winter, never in the summer so good that way but when it does come on it stays on for around 20mins after engine off - is this a thermostat issue please?

If it’s staying on for 20 mins after the ignition is switched off then that seems to be a problem. When I turn mine off it begins the shutdown procedure immediately and is usually finished (fan off) within a few minutes.

I’ll look up the rave system operation description and see if that’s an alternative heater shutdown strategy maybe caused by a bad sensor or something.
 
Seems the system should shut down within about 5 mins tops. There’s no specific fault info for what causes an overrun of the usual shut down time but it does say t4 software can read the fbh ecu for faults.
 
Hi guys the thermostat your talking about is this the one one engine cooling stym.
My temp gauge stays between cold and half way so I think my heater runs while I'm driving and turns of shortly after I stop.
 
Sorry guys just read all the thred.
Thermostat.
Were could I get online top HOSE thermostat and is it a nightmare to fit.

So yes, the reason the FBH is running is it's trying to warm up an engine which is being cooled by the radiator. The fact that the temperature gauge isn't reaching halfway, means the engine is below normal running temperature, which is caused by a thermostat which is stuck open. The quick fix is to simply put an in line thermostat in the top hose. That saves a 4 hour job replacing the factory thermostat, which generally only lasts a couple of years before failing again.

Search in line thermostat mod on here for loads of threads on the subject.
