Hi Guys, lots of thanks for the replies i have got for my problem
i am thinking of taking my car to the garage to be checked for the coolant problem
i tried today to feel the radiator top and bottom temperature ..
i can feel that i can not feel much different as the i drove only 9 miles in the morning before getting work, i can feel one of the radiator part is cold , i can find explanation it is the one being hit by the cold , the other part is warm..
