Ford 6.0L Power Stroke Diesel :: Coolant Flush With Thermostat And Coolant Filter Install

This weekend my friend and I plan on doing a coolant flush, new Mishimoto thermostat housing with high temp thermostat and install a Mishimoto coolant filter.

Truck currently has some unknown green coolant in it and Im going to replace it with Rotella ELC. I plan on doing a couple hose water flushes then follow with about 5 distilled water flushes. I've been reading about putting some Cascade in on first flush to dissolve any silicate goo that might be in there hanging out. I might give that a try. Im sure I can manage this part from all the stuff I read about doing flushes.

This is the part that looks like a little more work involved than the flush. Doing the thermostat kind of worries me because of the tight area in there to work with the fuel line and the EBP sensor being right there. The current thermostat holds temps around 175-185 under normal driving. I bought the new Mishimoto thermostat housing with the high temp thermostat installed in it when they had their pre sale going on for the housing.

I decided to just go with the whole thing because of all the stuff I read about people having issues with the thermostat not fitting the older housing correctly since Im certain I have the original housing from 2004, like everything else that's still original on my truck. I plan on removing the thermostat before doing the flushes and then installing the new housing and thermostat and coolant filter before I add the ELC.

The coolant filter install looks fairly simple to do so I should be ok with that.
