Adventures of Irontite and the Cracked Block
Seems an appropriate point to start a new thread.
Firs part is here https://landroverforums.com/forum/di...d-right-57996/ for anyone new to this.
I found out my viscous fan spins, so Im gonna replace that and put in a new thermostat before splurging for the radiator just yet (though you'll see I probably need to soon).
In the mean time, I have some pics of the results of dried Irontite. Result on clean parts is a nice fine white layer of coating. Dexcool-poop stuff, not so much...

What are temps before / after - if you have a scanner or Ultra Gauge ?
I would wonder if when doing something like this one would want to bypass the heater core, in case it was partially clogged. Obviously it is cheap to replace a radiator (labor wise) compared to the dash board pretzel wiggle.

I probably should have bypassed it, but I couldnt find my extra hose.
Temps with 190 thermo (and a bunk fan clutch it turns out), water and Irontite mix per other thread:
Its gonna just sit dry until I get the 180 stat. Will try to get a new viscous by then too.

At about night time air temps it idled, with occasional periods of throttle, at about 206-210 for 30 min.
Today I had it running for about 1 hour idling and driving to a car wash. It cooled for about 3 hours, then went to a target about 5 miles away. Temps were about 215-217 idling and neighborhood driving, 210-212 highway or with heater on, and occasional 221 spike under uphill load.

Your radiator looks a little crudded up, but did it solve your cracked block issue?

How do you know you have a cracked block, how did you test for it and why put a sealant in the system that is only temp at best and will just plug everything, especially the radiator.
Its a little early to say it solved it, but results are promising. No overheating and no pressure when opening the coolant bottle the last time.
