i said this because 4 years ago when i was in pakistan , i used to drive corola brand new 2.0d and lang cruiser 2000 . 2.0d was new and it used to do same thing as this city is doing , the temp was 42 in april . and ive seen it going upto 47 so there is nothing to be shocking at .
if this was lahore side i would say no im wrong , every one knows temp in karachi is much hotter then islamabad side and u said in some days some days its may around 37-42 max.....
so i said its like 40- 45
and i was there in april when it was 42 , it had same prob with my car thats y i gave him a suggestion
