Tony- had something similar happen recently in the 456. Warming it up after 6 weeks of non use and just as I was about to get it out of the garage, saw a stream of coolant running out from underneath the car. Turned it off, let it stand for 10 mins and then went for a short run, watching all the temps, which were fine. Rang Graypaul the next day, asking them (Craig) if I should be worried. Upshot is my coolant reservoir had been overfilled. Checked the (cold) coolant level with my finger and it was almost at the brim. And clean. Sounds like surge. Evaporating on a hot engine. HTH Kevin
Kev, thanks for reply. I think the problem is i don't have ANY coolant , or certainly couldn't feel any liquid when i checked ! I shall be sorting out today. Cheers Tony
