I've taken the car out for a few runs recently after not really driving it over the winter (apart from around the block). I noticed that the water temp needle went up pretty high when i was in trraffic and would drop again once i was moving. I was alarmed so i checked my coolant levels when it had cooled down, and it was low. So, i topped it up and bled it. A few trips later all was well but now it's started again. Seems like i'm losing coolant somewhere, anyone had this or know where to start looking?
Help appreciated, i need to get this sorted quite promptly..
