I had to come back to mud and look up the threads on changing this little bastard of a hose, Luckily I had one of the Wit’s End’s PHH replacement hoses in the shed from ages ago (people are now saying wit’s end has closed?) anyway, This job is genuinely a massive dick drag, but once it’s done you don't have to worry about it ever again, this is definitely not something I would want to to on the side of the road. What made things easier for me was having a swivel head ratchet to reach down from the top to that mounting bolt for the hard line, removing the bolts for the auto box dip stick tube and flexing that down out of the way and having a heap of socket extensions to reach the hose clamps on the PHH from under the chassis rail. If you’re about to take this on, have at least a full day up your sleeve, be in a good mood, work in the shade and be able to run out and grab parts/tools you don't have to finish the job. I had to go grab a coolant fill/bleed funnel thing that fits to the top of the radiator, plus green coolant and a swivel head ratchet.
