Just want a bit of help really on my mum's car...
Basically the heating hasn't really been right since she's had it (had it about 6 months now). The car's heating switch would only work on settings 3 & 4; worked this out to be the resistor pack and i've ordered the open coil resistors off Rezpax on ebay. Anyway back to the reason why i'm here...
The car's heating only works when driving about. When the car is stationary, the heating is freezing. Simple words. The car does not overheat as far as I am aware, thinking this may be an airlock of some sort, or worst case scenario a blockage.
The engine is passing coolant through fine, all pipes getting hot as they should, apart from the bottom hose on the radiator. Now I know this is suppose to be 'colder' than the top one due to it beeing cooled down through the radiator, but it's not even got a temperature on it. Feels like the car hasn't been started all day.
So last night, gave a few pipes a bit of a squeeze (without undo-ing any bleed screws etc) and now the heating is permanently cold. Not a head gasket problem, no white/blue or black smoke, and no oil in water/water in oil etc.
It's making me think whether it may be the thermostat stuck, or a clogged radiator, but i'm more of a Fiesta guy with all this and not used to the Rover procedure.
It would be of GREAT help if somebody could tell me how to bleed whichever relevant system for the heating etc. I know there is a bleed screw on the coolant rail between the engine and airbox, seen this last night.
Also it would be great if someone could explain the best procedure for cleaning the radiator out at an attempt if you think it is this.
Thanks muchly in advance
