you're right, I couldn't find a video that covered the whole thing.
lemme see if I can remember all the steps.
-start nose up and remove all the things in your way
-loosen temp sensor so you know it's not stuck
-remove t-stat housing and catch fluid
-clean mating surfaces
-drill little hole in t-stat if it doesn't already have one
-install t-stat using a tiny drop of gasket maker at 12oclock to hold it in place
-install housing using gasket (I prefer using a gasket with no sealant because a dry gasket doesn't care about a coolant dribble and it makes the job easier next year after the t-stat fails, lol)
-remove temp sensor
-pull rad hose and fill until fluid comes out temp sensor hole
-put everything back together
-fire up engine and check for leaks
-loosen temp sensor to remove any bubbles
-tighten back up and let truck warm up
-check for leaks and overheating
-keep an eye on the overflow bottle level and add as necessary
