Glad you solved it!! And it didn't involve having to replace a rad (the diagnosis from 2 x garages was almost right -ish, and wasn't something internal to engine, phew!). Hope you had a great time at Le Mans, looking forward to the videos!!

Quick question...if you leave the reservoir bleeder open (in the up position) and drive the car, does water come out of it? I had read a while back that you can just open it and drive the car and it will "self bleed" . Then you just stop and top up the coolant and you're good-to-go. Does this work or are you just asking for a mess in the engine compartment? Thanks, -Tom.

Great work, keep it going, i saw Val Rossi won something at Le Mans last week ?? But what r u going to ??
