Managed to break the glass in the (single glazed) window in the garage, so need to replace it.
It is a pretty old windows (~50 years), and the glass seem to be held in place using putty.
Before I take the broken one out - how do you go about fitting the new glass in its place? I know how to do that with wooden windows (nails to hold glass in place, then putty over), but what is the technique here? Also, do you use "standard" putty with metal windows?
TIA.
There will (should) be metal clips that fit into holes in the rebate and onto the top of the glass, which hold the glass in place. and you then use
*METAL* *CASEMENT* putty over the clips.Take care to recover them when hacking out the old putty - and the method of puttying the glass in is similar to a timber window i.e. Bedding putty, glass, clips and puty bead to finish.

1/. Clean out all old dried putty
2/. run a bead about 2mm thick to bed the glass on
3/. fit glass onto that compressing till its well sealed4/. apply thick fillet of putty with putty knife
5/. trim off excess6/. wait a day then clean up marks with turps/white spirit.
7/. paint putty with oil based paint while still soft.
never seen these in 50 years. Only on greenhouses. Anyone who fits glass dry with clips and puttys, is a tosser.
No clips. Waste of time.
Is there a more modern version of putty? Eg dries faster and doesn't crack over time?
Still using them before finally retired from the tools around 2000 - and you don't fit them dry. You stick a bedding putty under the glass and then use the clips.
Nope, you can still fit the glass without the clips providing you use metal casement putty, or use glazing mastic as bedding.

There is but it cracks even worse IME - 'Butyl' putty. Birds like it too.
You might try silicone :-)

With metal frames you don't want putty that dries. Special putty for metal frames allows for the expansion movement. Also cut the class smaller than the frame or it will crack in the winter when the fram shrinks. (I have never seen clips outside a greenhouse)
I would like to add to your post the following TNP.
Making sure that there is absolutely no old putty, rust or high spots left in the rabates - If you don't, the likelyhood of the new glass cracking when bedding in will be high.
Knead it well to ensure that there are no lumps or 'bits' in the putty - for the same reason as above.
Applying pressure to the glass covering the rebates only - never apply pressure to the centre of the glass when bedding it and always wear gloves or use a thick, clean duster.
Use the fingers to apply the putty fillet, using hand pressure to compress it into the rebates rather than the putty knife at this stage. Doing it this way allows you to get the approximate bevel of putty and making the finishing a trimming easier.
Using a putty knife (or old wood chisel or a small, flat paint scraper) at an angle resting on the outside of the rebate and following the inside rebate line pressing down and using a clean 'sweep' the full length of the rebate being worked on thus forming the correct bevel and cutting the waste in one operation. Try doing the operation in one, as 'playing' with the putty at this stage trying to get a finish is usually far more troublesome than need be.
No need for that, you should be able to get the finish at the first attempt if the putty's not too 'wet'. If the putty's 'wet', dry it off by wrapping it up in an old newspaper and gently hand-knead it for a while until the right consistency is attained.
You should let the putty 'dry out' for a few days before painting - painting while its soft, at best you'll get brush marks in it, at worse, the putty will take a long time to dry - and that's the last thing you want if there are no clips holding the glass in.
For further info see:
When you chip the putty out, you will likely find there are little pins through holes in the frames.These just tap out with a hammer. Some people don't bother with them.
Paint the metal first before appling putty. Paint the putty bead afterwards too.

Chisel out the putty. You will find there are little holes in the frame for metal pins which hold the glass in. They usually come out quite easily and need to be put back. Paint he metal before you put in the new glass and putty, it helps the putty to stick. Oil based paint. (ie the traditional stuff.
