Ok so I had the AA out again today.. There's something really wrong with the KA but I don't know what to do!
Symptoms: No heat from the heaters No cooling fan cutting in No pump cutting in No coolant! (been regularly topping this up) Steam from the exhaust(I noticed this ages ago but the AA man pointed it out)
Result: Warning light for temp on Last time, the header tank expanded like a football (I drove it a few miles)
Checks made: Water pump cutting in fine Fan operating at correct temps No exhaust in coolant system Pressure checked coolant, no leaks!
A bottle of K-Seal was used today and AA man says this has stopped the steam?
Suspected parts: Thermostat Heater Matrix Water Pump Head Gasket
Any and all advice/notes appreciated here, I'm at my wits end!

Na. Have you got oil in the coolant. Is there a yellow sludge on the oil cap. Sounds to me like you do have a coolant leak, is there no residue under the car when it's sat? If the water goes before the thermostat opens then you will get the fan temp light and all the warnings. Steam from the exhaust doesn't mean alot, my sport does that normally, it's a normal by product
Oil in the coolant = No Sludge on the cap = No Water under the car when sat = No Wet carpets = No
Lost coolant before thermo opening = quite possibly!
Another suspect thing is that the back window (recently rain-X'd) still steams quite badly and was actually running/dripping with water 2 days ago but I cleaned the interior paintwork when I rain-X'd so that could explain it.
I'm certainly up for having a crack at the thermo!
