I'll check the fan now. Just ran the car from cold with coolant cap off. A lot of bubbles coming out of coolant. Seemed to settle down after about 10 minutes and coolant dropped from top to empty. Then when I turned heating off it went mad and dumped coolant all over the floor. Opened heater up again and it settled down until I turned it off then went even more crazy and emptied most of the coolant on the floor. Bubbles all the time.... Pretty severe. Classic sign of head issues!
Radiator felt cool the whole time, car didn't overheated and rad pipes not over pressurised

Hello,
So the guage went high and no fan cut in.
Mechanic sounds like an utter cnut for not telling you or fixing the issue even after getting the car back to replace the water pump.
I'd check that the fan motor still turns, with the ignition off, so you can see if its free and not seized. Then if it free look at the thermoswitch. Looking at the photos here the thermoswitch is at the opposite of the water pipes, unplug the connecter and short the two terminals with a cable and see if the fan operates. If the fan operates then the thermoswitch has failed. If nothing happens so check the fuse isn't blown.
