To be fair I've had to refit the pollen filter three times before and only the third time stopped the leaking and I have no idea why!
That clamp definitely looks wonky
Managed to get in there firstly with some long nose pliers and alter the clamp by rotating it so that it faces upwards. Once done I got in there with some bettergrip, reseated the hose and feel happier... however...
I found the coolant was dripping onto that hose from above from one of those black electrical cable protectors with a fairly consistent drip every minute or so. Tracing it back it seems the coolant is weeping from the coolant flange that holds the coolant temp sensor where it meets the cylinder head, looks like it drips onto the hard lines that share the flange mounting, then the drip transfers to the cable protector.
New flange and o-ring seal ordered as being plastic I dunno if its slightly warped or just the o-ring gone.
As I need to replace the radiator fan switch and wil need to drain the coolant I may as well do it at the same time.
Also found the upper gearbox cable it missing the clip that holds it on to the gearbox selector - oh the joys.
I'm struggling to find a part number for the retaining circlip - the yellow item #1
@Thai-wronghorse - do you happen to have any?
