Yep... Really strange, just need your thoughts really...
Drove 90 miles this morning to Ashford, pretty much all motorway mileage, the old girl was superb, no issues what-so-ever... Parked it up and 30 minutes later, one of the engineers walked in and says the S2 is dumping all it's coolant...
Initially, we thought it was the aux rad by the way the water was sprayed back into the engine bay, but it turns out it's an inch long split in the small flexible pipe that runs from the water pump, to the metal feed pipe to the rear of the engine... BUT, it's located in a right pig of a spot. So it's a Rad fan out job, pipes disconnected and some rummaging around in the Electrostar train toolkit/parts bin and we've replaced the pipe with 3" of serious high temperature hydraulic piping... All I can say is thank goodness it failed in such a resourceful place with some very skilled engineers.
Topped up with 90% water, 10% G12 (it's dumped that much coolant that my half bottle of G12 went nowhere)... It came home without issue... Drove to Maidstone services and checked everything was okay, then kept a close eye on it the rest of the way... The last 10 miles I opened the old girl up a lot...
as in a LOT, nee - right up.... (Really have forgotten how mad S2's are! 
)... Left it idling on the drive and waited for fan, then after run pump... all's well...
There's only one question really...
Was it just a fluke of good fortune, or was there a reason why the pipe failed after the engine had shut down?
I'd guessed it probably wasn't through a pressurised (head gasket type fail) cooling system... But with the engine driven pump (sorry Railway technology creeping in here) shut down and the after run pump possibly in system, the coolant pressure should have been reducing...
Any thoughts?
