You can use either NAPA - ST85 Or Ford Powerstroke relay NAPA - ECHGPR110 You can also cross those numbers at any other parts house and get one cheaper if you don't like NAPA's pricing. The Ford relay looks different, but works the same. Later, Joe

No, the 1010 uses the same radiator as all the other CUCVs, all of the pickups and Blazers use the same radiator. BTW, you did notice that this thread is 2 years old right? Later, Joe

Did you bleed the front brakes too? Might need to do that. Also, did you use DOT5 fluid with the brakes? The stock CUCV has silicon brake fluid and there is some debate on the compatibility between DOT3 and DOT5 fluids in the system. When I've had dash brake light issues in the past, after...

The previous threads are not wrong. If your relay works as you describe, it is the wrong one. The 12V is provided by the pink/black wire and the light blue wire is the ground. There are two types of relays like the GPR in these trucks. One is a base grounded unit, it is grounded through the...

Close, the two Bosch relays are for the Voltmeter and Gen 2. Basically the same thing, isolating the 24V from the 12V cab circuits. Later, Joe

The A2/A3 trucks were not delivered from GM as a dually. They were a 1028 that was converted to dually with a kit that was put together by GM for the military. The kit came with a D70 rear. Later, Joe

I'm fairly certain that the A2/A3 kit was exactly the same. The only things affected were the fenders, hubs and rear suspension. The only difference is the designation based on which truck was used for the conversion, a 1028 or 1028A1. All of the CUCVs came with 4.56 gears except for the 1009...

Do not use a compact pickup to pull a full size truck... you're just asking for a world of hurt. Get a bigger truck or go see what is wrong with it and try to drive it home. Later, Joe

FD is Fire Department modification. If it came from GSA and not GL, it could have been used by a forest service as a fire vehicle and they can make a bunch of modifications. BTW, a civvie headlight harness may not work because of the blackout lights. They are in the same harness as the...

That is correct, they are all in one loom that comes from the firewall main plug along the inner fender, goes through the support behind the overflow bottle, runs outside just under the bottom of the grille, and back in where the NATO slave cables go through. There is a ground on the left side...

Welcome to the site... First off, the headlights are on the same circuit, not separate. You can download the tech manuals from the 'Resources' tab at the top of the page. You are looking for 9-2320-289-##. The wiring diagrams are in the -20 and -34 manuals. The first thing I would check is the...

I don't know about the GM stuff, but I've installed cruise control in three Ford trucks and two Jeeps, all I needed for them was the cruise control box, the servo, speed sensor and the buttons on the steering wheel. For the 79 Bronco, I needed to pull the small harness to the control box, but it...

As far as I know, the pump is the original 1985 pump. It leaks like a sieve when it's off to the point that it's hard starting in the morning. The quote I got from a local shop was $5-550 so if the consensus is that kr is a good vendor, I'll probably be ordering a pump from them after the new...

The resistor is the big black box looking thing attached to the firewall directly behind the air cleaner. It is only available through the military supply system or surplus unless you get a used one. It is not always a failing resistor that causes the glow plug failure, it is failing glow plugs...

As long as the plugs are not swollen, yes it is like spark plugs except no gap. If the tips are swollen and won't fit through the hole, then you will have other problems to deal with. Do a search for 'swollen glow plug' on here for detailed suggestions on how to get them out. The general...

Hi Mark, I'm in need of having my 1009's injection pump resealed because the throttle shaft seals are shot and the leak is getting worse. I've been contemplating finding a local shop to do the work, but that looks like a really good price for a reman'ed pump. How well did they handle the...

The M1010 is not any heavier duty than a standard M1008, and they have the problematic DUVAC charging system to boot. As others have said, if you really want a CUCV pickup, get a pickup. If you end up not getting the ambulance, please pass the info along so someone who wants a 1010 can get it...

The Duvac system is in the 1010 ambulances and some late 1028s. Most that I have seen are the 86's but there might be some earlier ones too. The Duvac system is a 200 amp 24V system with two 24V alternators in parallel instead of two 12V alternators in series. The Duvac controller is a blue box...

Reading over the TM, the 208 is very similar to the 242 I did so it's not hard if you go slow and pay attention to where the thrust washers go. Do make sure you have a really good pair of snap ring pliers, both the type with pins and the flat pads because those snap rings are big and very stiff...

Even better than a Chilton's, why not download the -34 TM because it has more detailed instructions on rebuilding the T-case. I've rebuilt a NP242 transfer case out of a Cherokee, they aren't very hard. Just take it slow and keep up with all the bolts. Later, Joe
