and finally, put the housing back on the engine.
I had already sprayed the bolts with WD-40 at this point.
Finger tighten both bolts and then just snug them with the socket. No need to crank them down.
I also sprayed the inside of the hoses witt W...

Then put on the gasket and (not pictured) more silicone.

First, I put silicone on the housing itself. Make sure you get around the bolt holes.

When putting the new thermostat back in the housing, make sure you put the correct side in.
If it is reversed, the truck will run hot.

I also hit the engine side with sandpaper and wiped it out the best that I could.
Once wiped out, I started the truck for a few seconds so that the water would flush out anything I missed.

This is after scraping off the nasty gasket and hitting it with sandpaper to clean it up.
Once I finished this, I also cleaned up the hose inserts and then wiped everything down with a rag.

I was able to take the bolts out using the 12MM and nothing snapped. (yah me!!!)
This is what we are looking at. The thermostat has seen better days and the housing is nasty. I had to use a screwdriver to pry out the thermostat itself,

The upper radiator hose was simply removed from the housing and shoved to the side. I found it easier to take the heater hose off of the housing first and then remove it from the water pump completely to get it out of the way.

Here we can see what we are dealing with. I removed the air intake hoses already and I have been soaking the housing bolts for three days with WD-40 already.
I still need to remove the large Radiator hose and the small heater hose
