Hi i have a 2011 transit connect and wondered if the i could get some advice on here on heater matrix not getting warm, when i checked the antifluid tank the pressure came backa nd a mucky type fluid was appearing as though the fluid was filthy, firstly is this right, its never had a flush is it worth getting a flush done through the radiator and heater matrix and would that solve th lack of decent heat from the blower, many thanks for any help recieved, colin. from staffordshire uk

 

Is there any blockage in the pipes?
