Depending on the compression ratio of the engine once air starts to get in to the 20'F to 40'F range it can delay injection ignition timing.
IDI diesels tend to run higher compression so the ignition delay effect would be restricted to below freezing.
Oh and if it has an EGR, make sure it doesn't when you are done with it.

I hear you re "too cold"- I'll certainly try to avoid that, as can quite often be below 0 degrees C here over autumn/winter
compression ration on the AAZ lump is 22.5:1- so should be fairly resilliant!
I'm away to google EGR removal
