Hi does anyone know part number for the top hose from thermostat housing to top of rad please

Also what is the int and ext diameter please.

I've tried to look online but can only find bottom hose.

6Y0121049D, probably. Part numbers are usually printed along the hoses, somewhere.

Thanks Pete 👌

Just seems they are impossible to get hold off and mine has gone all spongy.

Lol your way better at finding parts than me 

Oh I did not get chance to look and gone.

I posted this link, but then noticed where it was coming from and the near-£60 total price including delivery. https://www.ebay.co.uk/itm/256436832151

Just measure the end fittings it goes onto and get a bit of standard hose the right size. Then arrange the length so it goes round the bend without kinking.  Looks like it's same diameter both ends which makes it easier.

This one's a bit cheaper, for some reason, still Croatia: https://www.ebay.co.uk/itm/256436815637
