hi
im dirving a fiesta mk4 and when finished a drive there is a lot of steam from the radiator. i open the hood and the water storage for the engine seems to overflow through the cap and has a dark murkey colour to it. not knowing too much about this im not sure if there is a connection between water for the engine and the radiator. the cooling fan seems to work ok for the rad. sometimes i turn the car back on as to let the fan have more time cooling the rad. has anyone any advice on what could be causing these headaches. any help appricated no matter how little.
