lol na the car was already up to running temp as i had it running bout 45mins earlier.

dunno if im just clutching onto straws here but i do feel it just be a blocked pipe. guess the only way to find out is when its daylight 2mor take all the water pipes off and check them. (another wasted £10 worth of coolant )

dont worry not gonna purchase anything yet untill i know ive eliminated all other possibilities.

fingers crossed
