Just a quick question I have a ih 674 has d239 and she is leaking antifreeze around the injector sleeves can and are they hard to change
 
Probably have to, or should, pull the head. I did the ones on our DT436 as the machine shop didn't rant to install them. Just have to be very careful to get it slit, or crumpled on one side so it can be removed, WITHOUT NICKING OR DAMAGING THE HEAD!!!! Juse have to be very careful, have good lighting. Cleaned up the holes in the head with a small wire wheel on a die grinder, turned down a piece of oak to fit the inside of the sleeve, put the injector sleeves in the freezer, and put the head near the woodstove for a bit. Popped the sleeves out of the freezer one at a time, covered the sleeve in sleeve retainer (loctite), and drove it home with the tool I made. Worked very well, they had a good feel when they went in. Runs good, that was done a few years back.

Pulling the head will only add cost and effort to a really easy job.
 
I only did because my head was already off,
but if it wasnt, I wouldn't want any sort of
grit from properly cleaning the bores to get
into the cylinder itself. Even with a vacuum
or such, I wouldn't trust it would all be
out of the cylinder. But then I probably
spend more time cleaning my engine parts
than most. 3 times, once with a pressure
washer, once with brake clean and air, and
one last time with brake clean and air just
before that particular piece is installed or
used.

The 400 series nozzle sleeve is easy to R&R with tools you can make yourself that doesn't require slitting, crumpling or any of that stuff.
The only surface that needs loctite is the outer or upper end that contacts the cylinder head,(use an accelerator primer on the brass) loctite under the lower end of the sleeve could prevent the sleeve from seating tight against the bottom of the bore in the cylinder head. You want good brass to iron contact there.

I've changed numerous nozzle sleeves wherever the tractor was located. It's not rocket surgery.

And I'm also real particular about debris getting in the cylinder, I stuff a bit of paper towel in the sleeve before threading the puller into the sleeve, but reality is that dusty debris will simply burn up as soon as the engine fires.

Here's the instructions straight from the IH service manual.

I would recommend stuffing a bit of paper towel down in the bottom of the sleeve bore to prevent brass chips from dropping into the cylinder.
