Thanks for those thoughts Andrew.
What’s your view on the warm air in the intake duct, is that normal?
Hi, I have certainly not looked into this. I would not expect hot air to come out of the air inlet. I'm assuming that the blower fan is working correctly and air is coming our of the vents in side the car? In reciurculation mode the outside air vent is blocked and no air can come in or out. In normal mode, the fan should suck air though the inlet and into the car.
Also and to answer your question about the water pump...this is actually quite interesting as the water pump was changed with the cam belt 3 months ago and it was straight after that work that the heating issue began.
That certainly is an interesting coincidence. Something that should always be considered is that a new part isn't necessarily good by definition. Thus, even newly replaced parts should still be considered as potentially faulty when troubleshooting.
Given that you are having coolant problems which started immediately after work had been done on the coolant system (changing the water pump) does seem give strength to the two being connected. The new pump may be defective when supplied of may have been damaged during fitting.
Coolant would have been lost when changing the pump and so you could have air locks but the mecanic should have purged the system afterwards. You also have done this yourself, but the problems persist.
