Odd problem

[aaronshort]

well i used stopleak, and it has caused the most random things, at first it was ok on the driveway and when i got to gym, then leaked a little on the way to asda, on the way from asda to home it overheated the stop light came on and i pulled over, after that it was ok, i drive to work and back and its fine.
drive it today it was okay, then i drove to a birds house and its pissed coolant everywhere when i got there, then when i drove home it got a little hot and but only leaked abit.
Given up, im changing the rad tomorrow, got a second hand one of ebay
