Here is how I did mine. There may be some ideas worth a look.

I just went to photobucket and copied a previous pic.

Here it is.

Something else is going on here...

 

It's a conspiracy I tell ya

 

I'm at work right now, but will check photobucket this evening.

 

Now that is a conspiracy!

 

Pics from yesterday should be working now?

 

Now I said the T-case shifter was "FOR" a twin stick set-up...never said I was going to be doing this project right now....

 

Oh come on, you know once you start messing with things like that.........

 

I disagree. When towing I would start in low range quite often. With the hubs disengaged, it is much easier to shift from 4 lo to 3 hi with the twin stick. With the stock linkage, I would have trouble with both shift rails moving together, and the transfer trying to go into 4wd hi all at once. Without the hubs engaged the front driveshaft isn't spinning, so you can't engage the front output again.

Probably not many folks who want to shift like that, though.

 

That is one good reason. It just is sooo much easier to shift instead of fighting a single stick. That there are good reasons to disengage the rear and use just the front.

 

So I needed to install the water temp switch for the electric fans...so decided I would tackle a couple projects while I was in there.

Saw a 1st gen'er post up about using a funnel to drain the rad,....so i used his idea.







Once rad was out of the way thought I'd pull the T-stat and check it...not that it hadn't been working properly.





Looked a lot different then the one I pulled out of my 89 motor.

 

Gave the T-stat housing, lift hook and alternator bracket a quick cleaning, and a few coats of paint.



And figured since I had the rad out I would use T-mans idea on flushing the rad.

Couldn't find any oxalic Acid (Wood Bleach), so decided to try some CLR type cleaner. Boiled a gallon of hot water and mixed the jug in 50/50...thinking now I should have gone full strength?

Cores Before...





Then Neutralize with pool PH up...



And after...





Not much of an improvement.

 

Pulled out the nipple down below the T-stat housing on the block...required some big vice grips, and a bunch of heat to get it out. Then a 1/2 NPT to 3/8 NPT adapter.



Switch is on at 200* and off at 185*.

Then reassembled everything.

 

Figured I'd make a new air dam for the top of the rad. My original is cracking and very brittle. I've had this stuff kicking around for a few years now...thought it would work perfect.





Then used the original to trace out a pattern.



Cut out the new piece with a sharp exacto knife, and used a leather hole puncher to make the holes.



And installed....think it turned out alright.

 

Popped the plug out of the top of the head by the T-stat and filled the rad and motor with coolant, then went for a drive. Well the friggin T-stat is stuck open! Motor will only get warm...and the needle on the gauge...which has always worked, and I never touched it...only get just off the cold side.

When I had the water boiling for the rad I tossed the T-stat into it make sure it opened and closed properly...seemed to from what I saw...but clearly something didn't work right, or I did something wrong.

Let it sit tonight, and go for a drive tomorrow morning and hope it starts working. If not guess I will be pulling it and swapping in the T-stat from my 89 motor.
