Thanks for this! I'll be having a good read of that over the break.Not sure if this will be of help to you but have a read through this lot: https://www.landyzone.co.uk/land-ro...hen-coolant-leak-and-cracked-manifold.381697/
When I got mine it had a very slight coolant leak which quickly escalated. It was the alloy pipe set on the NS inner wing that had a pinhole in one of them and that made it drip on to the chassis rail and run out of the back of the subframe as well as the front and across to the OSF too. It wasn't hugely expensive to resolve but you have to buy the part from LR as it is only for the L322 and I would suggest replacing the two control solenoids at the same time as it will be easier and you won't want to revisit this job.
FBH is in the wheel arch on the NS under the battery BTW. Not too bad to change at all but I'd doubt that is where your leak is.
Keep us informed.
Haven't managed to get out much to it recently which is a bit frustrating. Hopefully soon.
Thanks.
