Can someone shed some light on this please, parked my car up yesterday and as i was walking to the house looked back and it was pissing out liquid from under the bonnet. On closer inspection it seems to be coolant and coming from what looks like the thermostat housing, or what my haynes manual calls, the cylinder head outlet elbow. Do i just need a replacment one and if so where will i find one? Oh and its a mk1 ph1 1.2. Cheers for any help, pics:
