Project: In over my head (again)

[Old_Red_Jeep]

I made a lot of progress today. I spent all of this morning going through the 2500's wiring harness. I removed the ABS, cruiser control, HVAC, lights, radio, and other circuits that I won't be using. The harness is a lot less menacing now that it's a bit smaller. It was still an intimidating job. Took me about 4 hours but it's done, and the engine still runs with it! I've routed it in a little bit but I expect to modify it some as time goes on.

All the engine harness stacked on the engine.


The gauges, ignition system, and OBD2 port. I'll change out the cluster for individual gauges later.

I also couldn't wait any longer so I put the front end back on!


Having the engine run plus the front end back together is a huge morale boost! It feels like I'm working on an actual truck again! The engine fits nicely but the front is still tight.



I'll probably need to remove the threads on the water pump pulley to make room for a radiator.


I also need to fix the radiator mounts as I go. A prior owner had done quite the hack-job before me. I really think I may be able to get it driving by the end of summer or early fall!

Also, my driveshafts came in!

Yesterday I was able to work on the fuel tank a bit. I cleaned it all up and painted it with the chassis saver paint that I used on the frame. When I was installing the module, if I use the o-ring, I have trouble getting the retaining ring to thread correctly. It jumps off the thread. If I don't use it, it's fine. I may use sealant instead of the rubber o-ring when I install it for good. Next on the list of projects is basically everything. I want to focus on the power steering, power brakes, cooling system, and A/C system. Once I get all that sorted out, I can focus on the rear end and maybe test drive it!

It's been a busy week this week at work and home but I've still managed to make a little progress on the truck. This week my reproduction rhino grille came in from a gentleman over on the ifsja forum. It looks pretty good! I can't wait to get it mounted and painted.



I also ordered a bunch of steering parts, cooling parts, and brake parts from summit and most of it came in yesterday. I was able to finally test fit the thing that I've been dreading, the radiator. Luckily, it fits like a glove!



There's enough room between it and the engine (I'm going to use a pusher fan) and it shouldn't take much fabricating to make it work.



I got an aluminum 3-pass radiator to hopefully keep the V10 cool enough. I need to weld in the driver's side radiator brace then a friend of mine will TIG on some tabs to the radiator so I can mount it where the 715's radiator originally mounted.



After that, I want to piece together the brake system and steering system so I can have all of the engine accessories and engine bay sorted out. I still am on the fence about putting A/C in it. It would be nice, but I'm not sure I have the room for a condenser in front of the radiator.

What application is that radiator for?
It looks perfect in there!!

It's a Summit 3 pass radiator.

It worked for me but that might be because a previous owner had cut out the driver's side radiator mount. I think Summit makes a couple different radiators with slightly smaller widths but I really wanted the triple pass. They're also completely smooth and don't have any mounting brackets or surfaces.

Speaking of, Last night I was able to fabri-cobble together the driver's side radiator support. I used a sheet of 1/8" steel and a section of angle iron. It's simple but should be effective. Now I just need to TIG some aluminum brackets onto the radiator to mount up.

Welded in and ground down for smoothness


It seems to fit really well.


I was also able to swap out the fuel injector on cylinder 4 and it's running normally now! I may be able to get the truck driving in a month!

NICE!!!
I love what you are doing here!
