Driving up the motorway yesterday morning, went into the outside lane to overtake someone and the temp gauge without warning shot into the red, dash "Bleeped" and the right light on the temp gauge was flashing.
Managed to get across to the hard shoulder, probably about 10 seconds of driving with the temp in the red.
My immediate thought was cracked header tank / loss of coolant as when I looked in the engine bay the top of the header tank (Around the neck) was wet.
Now, managed to get recovered home and let the car cool down.
I have checked the coolant level and the float is just above minimum (Hasn't lost a lot of coolant)
Next thought's were the dreaded water pump...
I ran the car up and let it sit at idle until the temp gauge showed the "normal operating temp" turned on the blower fan and set the heat to maximum.
There wasn't any hot / warm air coming through.
I felt the top hose from the rad and I could push it (System not pressurised) but it was warm to touch.
Next I tried the "coolant vent process" but couldn't hear any signs of the pump activating.
Now does this mean I have a knackered water pump?
Do we know if there is anywhere that will tell me what fuses the pump uses as I would like to check those before going ahead with a pump change.
Also, how difficult is this of a job to do at home? I am fairly competent with spanners but don't have a ramp so it would need to go on axle stands etc.
Any advice would be great as I can't drive my Zed at the mo
