I've checked water levels and they're fine, antifreeze is cool. the pipe leading upto the heater matrix is luke warm until I start pumping the water through manually. Even after the driving for 1 hour, I don't think there's an airlock...

Any advice appreciated.

I don't think its waterpump, as wouldn't it overheat? how would I check? could it be lack of pressure?

If you have to pump the water through, there maybe an air lock. Or waterpump.

Squeeze the pipes with the cap off to expell any air. What engine is it?

Airlock or a blockage in the heater matrix I would have thought.

It's a 1.2 spi. the pipes are hot apart from the one leading upto the matrix. I cleared the airlock as I'm getting warm air out of my blowers now. You think that waterpump isn't running right?

Fire it up and let it get warm, leave your header tank cap off bung your blower on full, on hot, and sit with it about 2-3k and this should expell your airlock fully, if this doesnt work then your waterpump could be getting lazy, where abouts does your temp guage register after say an hour of driving normally?

My 1.2 Spi was the same. Put a new stat in it (cambelt off job sadly) & flush & backflush the matrix with an airline & hose pipe if poss.

Prove its not the temp guage?

Also, if it aint siezed, or getting hot hot hot, why fix it?

it moves to the end of the blue, but not off it. il give that a try, if no joy then il give craigs advice a try. Matt because the thermo is telling the ecu its still cold, its pumping way too much fuel, the consumption is cr4p.

Thermostat mate definately, it should run at quarter not sat on the blue, my old spi did this too and yes because its not at running temp its not quite off choke so is over-fuelling too.

Cambelt off job to do it, so if its not recent id advise cambelt too (£9 iirc) and throw a water pump on it too for good measure:thumb:

Mines been doing this also for about a week. Thankfully my thermostat housing is at the front of the engine.

EDIT: Mines a 16xe so its in a different place to yours, not trying to confuse you. :)

Yeah that would be it, the cars last much longer than the original Wahler thermostat does.

The front mounted stat is a fine thing. It was a dumb thing for them to do to start hiding it behind the cambelt. Progress? Naah.

Spudly's right, change cambelt, & waterpump c/w o ring. (should come in the box) .... Especially if you are hanging on to the car.
