Which part number is this please?

A hose sprang a leak this week, with a fine spray of coolant sizzling on the top of my engine. I will get the new one from Craddocks, but I would appreciate knowing the part number. Thanks in advance for the member who looks in the parts catalogue. Full praise to the one who knows it off the top of his head!

Also, any advice please on draining the system to fit the new hose, and re-filling. I am not a mechanic, just an owner/driver. Thank you.

it could be 577292 or 594629 or 594632

i think it's this one: 594632

yer not wrong idle

open the jubilee clip on the block, pull off the pipe and let flavour flood out

p.s. also check core plug on back of head before changing pipe, just in case

Thanks all, I guessed I could rely on you. I also spotted a frayed fan belt which will be sorted at the same time. Just in time for the good weather seasons ahead of us.
