TD4 Coolant Temp Sensor size?

Elv73 · Sep 10, 2018

Can anyone confirm what size socket is required to remove the coolant temp sensor on a TD4?
Was planning on changing mine at the weekend before I realised I didnt have a socket to fit!
I think its a 22mm long reach but just wanted to confirm before I order one.

Nothing like 22mm!! I'll measure and get back to you if someone else doesn't !!

Strange because I have a 21mm and it was too small and a 24 was way too big so I was assuming 22mm?

Surprising.. 19mm deep reach. 3/8 drive fits best.

Nope, just been out to the garage to check the new one and 19mm is way too small as is 21mm.
I found a 23mm socket and it's only slightly too big so defiantly looks like a 22mm?
