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!

If you have no coolant then your heaters won't work, so sounds like you may have a leak.

The temperature light could have either been because of lack of coolant and the engine getting hot, or due to the thermostat not working.

The thermostat is a really easy one to change, takes about 10 mins to do and only costs £7 in Halfords!

Edit: Just remembered you have a Duratec engine. Thermostat isn't so easy on there as you need to change the whole housing. Around £50 something from Ford

Andrea,

The initial suspect has been the thermostat but the AA tech said that it can't be as the heater would still work? I have no idea about these things :s

The heater wouldn't work on either journey yesterday until a mile or two in, then it just cut right in with high heat (I had it set to max).

I might just order me one of those thermostats and have a go! I found a guide knocking around here somewhere and it looks doable.

Let's just hope I can get it home and I don't wake up to a frozen engine!

The heating. Ones straight off the cooling without the thermostat opening doesn't it ? The heating works straight from the turn of the key and gets warmer as the coolant beats up.

Ok, so without stripping half the car . How can I rule it in or out?

My best guess would be to stop using the heater?

Also, would that be causing the steam from the exhaust 0.O

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

If you were worried it might be the head gasket you can get the head compression tested. If its knackered, I have a spare 1.3 in stock with only 14,000 miles on it, so you could have it for cheap

Sounds to me like its a coolant leak though. Could even be the thermostat housing leaking!

That's what I reckon. Coolant is gone even before the thermostat has a chance to open.

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!
