    Little help, I'm on my back from training and my temp sensor has gone off and To my horror it's at 110!
    I'm siting in the middle of nowhere with the fan on waiting for it to cool down. Water pump maybe?! Or thermostat?? My blowers in the car ain't heating up properly now neither?

    Help!!!!

    i would guess that its the water pump. The water is not circulating around your engine hence the overheating and also not circulating to you heater matrix so your blowers are blowing cold.

    A sticky thermostat usually sticks open so the engine runs cold.

    I'll have to check the service history, prob around 60k when then cam belt was changed. It's done 110 now. Got home safely.
    Any one know any good specialist in the south London area? Is it a easy fix?im quite handy with tools.

    If the themo stat stayed closed, would it give the symptoms of ooverheating? I took off the coolant cap while idling and the coolant rose and splooshed around, when I put the cap back on, the coolant dropped?

    yes it would mean the engine would over heat but it would also mean that your blowers would blow hot air at you because the water pump would still be pumping it around the circuit

    Best way to check the pump is to open the expansion tank with the engine running and look for a return flow.
