Should the water pipes be hard when the car has been running a journey? I just gave them a quick squeeze and they feel presured up a bit. notsure.gif . I just took the water bottle cap off and it had a little pressure it it, it gave out a big hiss then all was calm. Well infact, the water level in the bottle sat at the right line, when I took the cap off the water level has risen above the line. I have too much water in now notsure.gif
