Title: H.P. aircon valve fitting
Post by: Jukeboxnut on 20 May 2014, 21:55:02
I have finally decided to replace the H.P. aircon valve on my car but I cannot find a spanner to fit the thing.  A 17mm spanner fits the hex fitting underneath it but nothing fits the valve itself either mm or AF.  All my spanners and sockets are too small or too large so before I resort to mole grips and brute force does anyone here know what to use?  Any advice would be most welcome.

I thought the flats on the valve were 15, purely from memory?

5/8" & 16mm are all but the same thing ...... which is a milli too big  ;)

Having replaced 2 recently, it's effectively a 14.5. Clearly no such size exists. Using a 15 at a slight angle worked well for me.

Thanks for the advice, I has a quick try earlier this evening but it seems stuck fast so I gave it a quick squirt of rust buster and will try again tomorrow.

Remember the 17mm bit doesn't turn, and is just there to allow you to stop the whole thing rotating and splitting the pipe.

Rust buster is an American product, a sort of superfine lubricant which penetrates and frees off just about anything so hopefully even ally, should find out later.

I had another try at shifting the valve this weekend but still no joy.  A 15mm spanner or socket will not fit it or the new replacement and a 16mm is far too large for either as is a 5/8 AF.  I tried an adjustable spanner but that just spun and started to round off the already minimal form on the flimsy ally fitting.  Did not dare to try the mole grips due to rather limited space and fear of sheering the whole thing off.  Anyone got any bright ideas what to try now?

mole grip is the way to go - lock it on with the handle as close to the cam belt cover as poss and gently pull......
