Yup, read up on that post but just a couple of questions. Have had the thermostats for a few years now and just getting around to swapping. They are 160. I think I have down the process to drain the AF but not clear on getting access to the thermostat without removing unnecessary components. I saw you asked about removing the thermostat housing vs fishing them out after removing the outlet connection to the hose. Assuming you had to remove the housing? Lastly, once the alternator is out of the way does it allow you to "slide" the housing out without undoing the small hoses connecting to the AF fill "tank" ? I'm just eye balling it now so I know what I'm in for once I start.Can't seem to find an indepth write up but there is some info to be found at this link: http://clubsearay.com/index.php?threads/official-cummins-6cta-450c-thread.77886/page-12#post-1019780
We did remove an alternator on one engine but then fought a bolt going back on. But if you're changing alternators anyway, that's the way to go in my book.
Drain the coolant off of one of the lines from the coolant filter going back to the low point on the block. Remove the hose at the filter. If memory serves, you shouldn't have to drain too much just to replace the thermostats (yes, two per engine) but if you're changing anyway, then drain the whole thing.
I bought my T-stats from sbmar. They were the 160 Deg F versions. Kits came with gaskets, etc need for job.
If you have any questions, fire away.
