Radiator Weeps when cold

[Biggriff]

So my GT4 has a radiator leak when cold start up. When its warm nothing. Anyone had this before?

[Twinfan]

Nope. Loose pipe/hose that expands when hot and seals up again?

Yes, or radiator end cap not sealing. I'm guessing its a 50p O ring and £500 of labour.
