This is an illustration of my luck.
Went back to car in garage after a short shopping trip and pool of water!
Bad coolant leak.
Turns out said leak is in a plastic section of pipe right under the inlet manifold, which necessatates removing the complete manifold to get off!
Couldnt be in a hose that easy to get off, oh no!
With dodgy hex head bolts that needed "work" to get them off, it took two and a half hours!
