I started today, doing some clean up, and organizing. If I cannot put bolts back in the part, I put them in a bag, and label the bag. The bag then goes into a parts box.

After doing that, I lifted the engine and then slid my parts washer under the engine, and cleaned the engine a little more.

Here is another reason I pulled the engine. I had to replace this plug in the block. you may recall, at the beginning of this thread I made mention of the block having a bad core (freeze) plug. Here is the new plug in the block, I actually put it in last night.

Here is the plugs I used.

Because I had one bad plug, I needed to check them all. Even the one in the back, under the flywheel. Before removing the flywheel, I put the engine at TDC, number 1. (and 4).

And after putting the engine there, I put a mark on the flywheel.

Then I removed the flywheel. This how I held the flywheel from turning when I loosened the bolts.

With the flywheel off, I did some more cleaning.
Then I set up the engine to pressure test the cooling system. I wanted to do the entire cooling system, so I needed to remove the heater from the truck.
The nuts on the studs for the heater were rusty. Like this.

The first step is to spray some penetrating on the studs, and nuts. You really do not need a picture of that, do you? Then you wait. Let the oil penetrate. It is much easier to wait, than to repair broken bolts. After waiting a while, try to loosen the bolt, or nut. If the nut goes a few turns, and then starts to get harder to turn, STOP! Spray some penetrating oil behind the nut, and then tighten it up again, but not tight.
This is a wire wheel you can get at Home Depot.

Put it in a drill.

and use it to clean the rust and crud off the bolts you are trying to remove.

After removing the heater, I pushed the engine on the stand under a rafter, and used pieces of twine to hang the radiator in front of the engine, and the heater behind the engine.

Here is a picture of the pressure test pump hooked up to the radiator that came with the truck.

If you look close, you can see a problem with the radiator, in the last picture. Here is a better picture, of a bad radiator.

Conveniently, I just happened to have spare radiator.

.
I took off the radiator that came with the truck, and hung the spare radiator, and tested again.
I found the lower radiator hose was leaking. I had a spare on of those, and changed it. Then I found a leak in the short heater hose, and changed it with another spare hose I had.
Finally, I got the cooling system to hold pressure.

This was after sitting for a few minutes. Success!
Before hanging the heater, I tested the motor on it.

It is running in the picture. Really it is.
This is the picture of the battery hooked up to the heater motor.

Today, I also went and got some parts for the engine. I got a hose for the PCV system, the hose was gone on this engine. Here is the new hose I got. I got it from Tonkin Nissan, in Wilsonville.

While there, I also got an oil filter.

and then I drove up the road to
Schuck's I mean O'Reilly auto parts, and got some Spark plugs,

So, that is enough for today. Maybe more tomorrow.
