Ok, so I done a fullll service with everything from oil filter to diff oil! Also done coolant hoses and lost a bit in process! I topped up the reservoir and went for a drive and she's nearly over heating, now the expansion tank is nearly full, so drained a bit back out, whilst topping up the radiator incase of an airlock? Now she reads kinda normal but on the internal heater, am only gettin warm air when I crank it up past 28/29 C.
Anyone with experience in this?
