hello all my vr6 is over heating big time ! all was fine driving it casually stop for some fuel , then as i went off down a side road i noticed the temp gauge had gone past the normal 90degrees and was heading all the way back round !!! stoped the car opened the bonnet to find the water bottle shooting with steam , very HOT ! let things cool off for a while filled the water back up then it was ok again , just sat there at 90 all the way back :| i keep having to fill up the water bottle as its going some where but i cannot see where as its not spilling over my garage floor. Do you think not r
