hello im new on here i own a 2001 51 reg is300 and have a few questions can anyone tell me what the tank just on engine side of the radiator is and should it have water/coolant in it or is it just an overflow chamber? if yes should it be full? also when i take the rad cap off there was a brown lime scale type substance just around the cap could this be from my heater matrix??? or is it somthing more sinister???
it has the clarion cd/tape radio how do i turn the trafic and news setting off as its driving me mad
also i checked the gearbox oil dipstick it reads about 5 mil above the full mark when warm is this a problem or will it cause problems??
any advice would be much appriecieated thanks richy
