I first tried a flexible hose on the upper radiator hose but the bend angle was too tight at the radiator inlet. Next I did some digging on Gates website and found the 22268, it's a 1.75" ID hose with two 90's on it. The length was about just right to cut a 90 off and make it work. The radiator inlet is 1.5" OD so I also bought the Gates 26391, its a 1.75" to 1.5" adapter...worked great.

Same story with the lower radiator hose, bend angle was too tight for a flexible hose. Back to Gates website...after quite a bit of digging (2.25" ID hoses are limited) I found the 22774 which looked usable after some cutting. Ordered one of those as well...

3rd pic show the upper hose installed.

My Cummins had the coolant temp sender installed in an NPT port above the thermostat, I preferred not to have a wire running across the top of the engine going to the sensor...not as clean.

I found a 3/4" NPT port at the drivers side rear of the block that would work well, however, the Autometer sender is 1/8" NPT. Went back to the Parker store and found that there isn't an adapter fitting to reduce from 3/4" to 1/8" NPT. They had 3/4" to 3/8" and 3/8" to 1/8" reducers, that was the best option, but it certainly wan't very clean.

So after a little drilling I slipped the 3/8" to 1/8" reducer into the 3/4" and welded them together...much cleaner.

Next I needed a coolant overflow bottle. Found a nice bottle from Canton Racing that fit the bill so I got it on order. Once again I used 1/4"-20 weld nuts to mount it to the driver's side inner fender...more pics to come on this.

Next problem I started digging into was the alternator. The factory alternators that Dodge used on the Cummins were controlled by a computer based external voltage regulator, obviously I didn't want to mess with regulating the alternator with these Dodge parts and with a winch and future lighting upgrades I needed a high output alternator.

I reached out to Mechman regarding their 250 amp S-Series alternator for the Dodge Cummins...but asked if they could make me a custom 1-wire/self-exciting version.

They ended up making a custom 1-wire version for me and after some discussion were able to provide the right DIA 8-groove pulley to still give good output at idle. I didn't want to try to find a slightly shorter serpentine belt, the pulley we ended up going with is slightly smaller diameter than the Dodge pulley but wasn't enough to necessitate a belt change.

Here are some pics. It was tested putting out 121 amps at 800 RPM idle and 250 amps at 1,800 RPM.

4th pic is comparing the Dodge unit to the Mechman. Overall all of the Mechman reviews I read seemed very good, hopefully its a great alternator. The quality appears to be very good and just the difference in the windings are substantial.

Thanks, much appreciated! It's been a lengthy project, it's fought me every step of the way, I guess that's just how it goes when everything is custom and nothing is made to go together the way you want it to

That alternator sounds fantastic. I did a lot of research on them before I got a Ford 3G. It works well, but not that good. It's only 130 amps. It does make lots of power at idle. I have the same alt on my DD and project. I'm planning to run 4 e-fans, so I may upgrade to yours.

have to laugh at the comment that you didn't want to hunt down a slightly shorter serp belt. you must be burnt out from hunting the rad hoses

Simply outstanding work!

Awesome work, but I want to see it on the trails. It's close. I've had a build going for several years now as well, but I have to do it in phases, and take time off in-between phases to drive it and enjoy it.
