run the engine with the header tank cap off untill it boils over, should push all the air out of the system, as it sounds like you may have an air lock, if that doesnt work then you may need to take out the heater matrix and flush it.

Is the engine running cold generally or just the heater. Does it warm up when stood for long periods for example in traffic.

could be your thermostat stuck open. car would never reach proper running temp, no heaters, low economy.
my calibra did this. soon as i replaced it, car ran better, had heaters back again, and fuel consumption returned to normal.

Didn't work... How the hell do i take out the heater matrix? I have airconditioning, and I just got a new alarm fitted... Would this have anything to do with anything? (I know it's a long shot).

i would start off by changing the thermostat and flushing the cooling system, thats the cheap place to start.
After that you could well be looking at heater matrix!

First check the simple things, like
1) when you turn the dial to hot, it moves the cable on the heatermatrix to open the valve
2) Feel the pipes going to the heater matrix are both hot, they are at the back of the bay in the middle and run in to the car.
To flush the coolant, you need to go to the local motorfactors and ask for coolant flsuh, you'll also need new antifreeze in there when you remove the flush solution cause it's a bit corosive.

Where is the heater matrix situated? How do I flush the coolant? What does it do to flush the coolant, how does it get rid of it? I know i'm dim.
