I found a little time yesterday and today for some quality time with the old van.
I started in on the new transmission cooler. The one I had installed before...
Being how much attention I pay to the fine details, I quickly discovered that the one I already have installed was LARGER than the new one in the box.
Super smart. That's me.
So what does one do when you've got a new transmission cooler, ordered specifically to be larger than the one you've got, only to find it isn't at all larger but actually 20% smaller.
You make a sandwich. That's what.
So now I've got a dual core transmission cooler that I can re-circuit if need-be down the road should one of the units fail. I actually feel pretty good about this.
Moving right along, I opened up the new Hella horn box and found that they draw enough current to warrant a power relay. So instead of just installing a pair of horns, we needed to wire up a relay first.
Have you seen how much room there is under the hood of a 1986 Econoline lately?
The horns themselves won't fit behind the grille so I routed the power wire down to the bumper.
Before buttoning up the grille I did some rust prevention and repair work on the upper radiator support.
Napa Rust Treatment to the rescue. I know I've touted this stuff before but I'll look for any opportunity to bring it back up....
Boomer maintains a "healthy" amount of corrosion as a result of this stuff. It doesn't do a thing on clean steel or paint...in fact, it flakes right off. Throw it on rust however and the stuff turns black as coal and hardens into a very tough base. I typically put a coat of rust treatment on the bad areas, then a coat of rustoleum "rusty metal" primer followed by my color choice of professional grade rustoleum enamel. All coats are brushed on....my expedition vehicle doesn't attempt to be something it isn't, and it isn't pretty.
Me being me, I did the black coat right before a thunder storm and closed the hood to protect the paint. Later in the evening I inspected the paint and found the insulation (which I'll be ripping out shortly) had stuck to the paint. So tomorrow I'll need to sand and recoat. Idiot.
Then on to the new Racor fuel/water separator. I finished up the new bracket and painted yesterday.
Installation went fine. I needed to add a 90 degree bend to get the hose routing correct, but in the end it was fine.
Getting everything purged went as expected...lots of engine cranking. Looks like the fix will hold and our fuel aeration issues are over for now.
While I was crawling around in the dirt I purged another 2 quarts out of the transmission circuit to get the level down to normal. Finally I'm reading at "full" when the transmission is warm instead of "full+a bit".
And since I was now dirty and covered in oil, I decided to pull the drain plug on the transfer case. I had never actually looked in there before so I wasn't sure what to expect. Pre-research on the topic led me to believe the transmission would filled with either ATF or gear oil. The stuff that drained out was more like maybe 30 weight motor oil (??). Anyway...all drained and I went to the store to get refill fluid for tomorrow along with a vent for the rear swing-out box.
Strangely, the rear box has been VERY humid. It is totally sealed so all I have been able to figure is that the water hose and blackwater drain hose are bringing water into the box, and once its closed the water evaporates with the heat (sun on box) and then condenses at night. The water I'm finding is clinging to the ceiling and upper walls of the box. Very strange.
So I'm going to add a vent to get the box a little dryer. We'll see how that goes.
