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...

 

more pics

 

and all for now

 

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.

 

Most likely will be needing that radiator, unless you started with a new one.

 

Nope, as you can see, that one had a nice coating of dexcool crud.

I guess the next report will be a little longer in coming, haha

 

I bypassed the heater core when using the irontite ceramic coat product last week. I had a misfire in cylinder four, have exams the next three weeks and study for the state bar after that. No time for a HG job (or replacing a block more likely with it being number 4). Anyway, I have been really pleased with the results and was planning on replacing the rad anyway even though mine is clean. I think the trick with irontite is to make sure your coolant system is not restricted before you begin. If you do that, I think it's a good product.

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.
