HI, I have a mazda bongo that keeps overheating, it has had a new rad and thermostat fitted, has been bled using the manufacturers recommended procedure and been checked over by a trusted and experienced mechanic who has used all kinds of gadgets and tricks of the trade to check the head gasket and suchlike. Does anyone have any ideas?

I dont know if this will help but those vehicles have a problem with the water pump impeler. Tell your mechanic to check this. A sign of this is the heater will not get warm althouth the car overheats. Jon...
