Hi my engine overheated and i had a loss of power when i checked the water level, as soon as i unscrewed the cap all the water started pouring out but i could not tell exactly from where, around the middle between the head and intercooler but too many things in the way to spot. If i fill it up with water and put the cap on it will hold the water untill i rev the engine and then it starts leaking again. Any ideas? could it be a perrished hose or is it more likely to be the water pump? Please help!

Thanks

Spark.
