No air con on mine so guessing the valves are standard fittment.

Found a manual in the boot so ill have a look at the thermastat and the bleed screws seem easy enough (looks rather blue peter needing a litre bottle lol), But ive got another thought. The cars got slider heator controls and the temp adjuster moves a bit to easy as if its not attached to anything am i right in thinking that the resitor packs for pugs used to break?
