Handle pulls off in the direction of the cable.
Coolant hoses usually have little ear clamps on.
Cut those off and pull off the hoses then try blowing again.
Then you can work out if the blockage is in one of the hoses or the head.
If it's in a hose try blowing or connecting it to the cooler while whipping it.
If the head try poking a bit of tig rod down there.
Hoses /heads can be replaced individually if it's that bad.
Either way, I'd flush the cooler and change the fluid unless you know another reason for a blockage.

Also worth checking the cooler is actually pumping under pressure rather than just making flow but if you have tried an airline on the torch it sounds more like a torch blockage.
I have flushed the cooler and it seems fine.
The hose is stupidly long.
If I cut bits off how do I reform the connections? They are crimped I think?
Also if I buy a new one are all the fittings standard? The water connections are push fit like on an air hose.

If you remove the outer crimp carefully you can reuse the inner part and secure it with a ear clip.
Cooler end will probably be a Rectus 21, Photos & measurements would identify.
Tricky to do alone but if you hold the torch head and blow air into both hoses individually you can sometimes feel where the blockage is and save removing stuff unnecessarily.
If the torch has been removed from the cooler or the fluid was dirty probably a foreign body stuck in a hose and might blow out from the torch end.
If it's not been removed but sat for a while probably crud build up in the head.
If you do manage to poke/pull some crud out of the torch head keep hold of it then you can try and find a chemical to dissolve it
Jusy remember hoses are more expensive than heads if you need to start cutting things...

Yes Rectus 21. Are those standard on new torches?

No, there is not really any standard.
Rectus 21 and 3/8 thread are probably the 2 most common, so if it looks like a Rectus 21 it probably is.
But there are at least 3 other types that look much like R21 but not the same size (so won't fit)
You can get adaptors from Threaded to R21 or its easy enough to change the ends over to R21 if required.
The power connector is more tricky so if you are torch hunting try and match that up first or make sure an adaptor for that is easily available.
You may already have an adaptor fitted to your existing torch as they are quite common.
Also check the electrical plug (if it has one)
They are often expensive so would save you a few quid if yours can be reused and fitted to a new torch.

He will want single ear rather than double ear as you need to fit the ear on the inside otherwise it will catch the body when it's reassembled

have you tried reversing the flow ,put hose on to gas bottle put 25 psi in if not clear reverse flow try that
All sorted thanks. It was a while ago now - but as a newbie you are forgiven - welcome to the forum
