The time has finally come! I got myself a 1985 CUCV M-1009!!!!





Hello SS brothers and sisters!





After many years of looking, I finally got an M1009 as I’ve always wanted. Long story short I got this from SS user 48cj2a. Below are his mods since he’s had it.







1985 CUCV M-1009 Project Milverado



(8-29-10)

Purchased a 1985 CUCV M1009 (Blazer) with 48K from my local Police Dept in a Sealed Bid Auction. They procured it from Ft Carson, CO so there is very little rust and it is in excellent condition. They drove it all the way from there to Central, IL.

They swapped the 6.2 into another CUCV they already had that was hydro locked and then rattled.

I've been searching for a donor vehicle (Suburban, Blazer or Pickup) as I don't know what if anything is missing.

I've was hoping for a Silverado packaged truck for A/C, Cruise, P/L, P/W and possibly except able door panels and seats w/console.

Everything in Central Illinois within 150mile range has been way overpriced so the look continues.

Pulled the 6.2 yesterday and got it on an engine stand. My concerns were correct as a few wires were cut on the engine swap.

I will pull off oil pan first, what else should I look at or look for from the hydro lock diagnosis?

Still looking for a donor vehicle for engine.

Went to the Pick a pull last Friday, scored a good 87 tilt column with cruise and intermittent wiper module for $60 came with keys so pulled the door locks as well.

Also grabbed the dual head lamp harness and turn signal lenses out of the broken grill, the fender Silverado emblems for a theme idea, the dash Chevrolet emblem and a/c vents and ducts above the glove box (trim piece has broken)

Thinking about going back for the p/w, p/l pieces but the harness looked like a bear to pull. Also would like to grab the dash speakers w/wiring and brackets. The cab corner ones were already gone.



(9-24-10)

Craigslist local score today off an 88 Blazer...

Complete firewall A/C box both inside and outsides with controls and wiring plus inner ductwork. Still need the radiator side condenser

Both front door panels, P/W regulators & P/L actuators plus all wiring and relays (man that relay was a bugger to get loose)

Rear tailgate P/W regulator and all wiring from the dash switch to the gate (frame mount wire clamp was also a bugger)

Both Buckets and Rear Seat

Spare tire

Need some Blue and Pink fuse box ends for the P/W wiring, broke the clips removing them.

All for $150 and some sweat work.


(11-15-10)

Have not posted since my Birthday in Sept on my CUCV Build but can finally say we are back on...

In the mean time I pulled the motor and got it on a stand to assess/diagnose the problem:

Had been looking for a donor in the mean time.

Scored an 87 CCLB on local CL with a replacement 6.2 Target engine, sounds like it runs good so bought it and they delivered it for fuel money yesterday.

87cclbleft1.JPG



I started a little body disassembly Sunday afternoon, getting one fender and inner fenders well off and the other one tonight. The DLS time is killing me with only about an hour of daylight after work.

Hope to get the radiator drained and the core support off tomorrow and get a good look for any thing I need to address before swapping into the CUCV.

Did find a fuel leak that ended up being a broken injector return line so swapped a good one from the old engine.

Hopefully when done I can part out or sell what's left and recoup some of it back.



(11-17-10)

Got the radiator drained, disconnected the radiator and heater hoses, oil and tranny lines, wiring harness, and have the core support loose but got to dark so hopefully tomorrow and pull it.

Also learned it is an emission free J Code 6.2 so that’s another plus.



(11-19-10)

Just about ready to break out the tripod halogens...Do have a 4 day weekend next week so depending upon what I get done this weekend, I should make some good progress.



(11-20-10)

Made some real progress today.

Took most of the day but got the engine and tranny pulled together from the Crew Cab. Instead of fighting the motor mounts I unbolted the frame mounts and tranny mount, disconnected the exhaust, driveshaft, speedo cable, and shift linkage and it came out with a little persuading. Found another of the 101 uses for the Hi-Lift Jack...

62lhframemt.JPG
62rhframemt.JPG


Had a large can of oven cleaner I've been saving for no reason and emptied it on both. After the clean up and separating the tranny It’s now on the engine stand to evaluate anything I need to transfer over from the original engine.
62cleanup1.JPG

62cleanup2.JPG



After getting the engine removed and looking over the firewall cover, I'm going to try and use it as well. Might give a decibel of noise reduction.
firewall.JPG



(11-27-10)

Fought the reinstall of the 6.2 for a couple hours yesterday trying to get the tranny bolts to line up so today I started off the moring pulling the dash pad, speaker, cluster, wiring harness, firewall covers, wiper motor, and stainless gutters on the donor Crew Cab. All went relatively well.

Then spent a couple more hours after on the 6.2 and decided to just pull the front clip on the CUCV.

It was a real pain with the bumper and brush guard on but I did get it off. I think I will probably take the fenders off when I reinstall it.

After I got the clip off the 6.2 seamed to go in a lot smoother and I got all bolts started and even was able to persuade the dipstick into place to catch the upper bolt and the starter shield to catch its correct bolt just at it got dark tonight.

I will say the upper two bolts started pretty easy from the top since I was not fighting a HEI distrib for clearance.

Hope to get them tightened down tomorrow and begin getting everything else hooked up.



(11-28-10)

Made better progress today...used the pry bar under the manifolds and was able to get the motor mount bolts in on both sides with a little frustration.

Got all the tranny bolts tightened down, center firewall pad mounted, p/s pump mounted, and the wire to the gas tank fished through the flexible conduit and connected, before having to stop and go for the annual quest for the Christmas Tree.

At least it was sunny but in the 30s versus last year with foot of snow on the ground.

Didn't get as much done as I hopped for my 4 day weekend but further then I was a week ago for sure.



(3-15-11)

Finally getting some decent weather again so spent a few hours Saturday and all day Sunday working on the CUCV.

Not getting 12v to the Alt and Glow Plug Relay for some reason. Dropped the starter to check the fusible links on the starter harness. Traced the wire to GP relay and is all good as is the wire to the Alt. Ran a separate 6 gauge wire from the battery to the GP relay it is getting fire. Took a few cycles to get it started and all the fuel lines purged but she took off after that and seems to run pretty good.

Disassembled the front clip and got the radiator support and passenger fender mounted. installed the Crew Cabs wiring harness in the dash and got the tilt column installed.



(5-14-11)

I swapped in the crew cabs interior dash harness and all the gauges work but the low water is staying on.

Installed the tilt wheel.

Ordered and received some red LEDs from superbrightleds.com to bulb the cluster and heater back lighting. I've seen some builds on cleanup, painting the cluster housing and may end up doing that (left mine stock light blue) as I'm not getting the results I'd hoped and heard from others who did it with redoing it.

Need to install the cigar lighter socket in the ash tray still and try to get the dome lamp fished (the CUCV does not have a dome lamp and has a plate tacked over the hole)



(6-5-11)

Weather is getting real nice and I'm finally catching up with other things so I can get back on this.

I have about a quarter play in the steering wheel from side to side so need to figure that out and hopefully close up the dash in the next few weeks, and take a test drive.

Anyone have any ideas on the low water lamp. I have not ohm’d out the wire but rad is full and the wire is plugged into the sensor on the tank below the fill cap.



(6-6-11)

Looking for all of the cruise parts for a 6.2...

I forgot to mention I was able to sell the 2wd Crew Cab locally on CL after keeping a few items. If you see my parting a 6.2 ad you will also see that I've been able to part a few items from the pulled CUCV motor so I'm actually at almost a $100 in the black from the donor truck purchase to gain the replacement engine.

The donor truck supplied 12V engine harness, dash harness, gauge cluster, good brown dash pad, engine, radiator, firewall insulation and a few items I actually resold separately.

CUCV options added to date:

firewall insulation
tilt wheel w/intermittent wiper switch and cruise
gauges (oil pressure, water temp, voltage) and red back lighting

power locks and windows including tailgate ready to be installed

gathering A/C parts

Wiper and Washer Upgrade from 87 Chevy Crew Cab

Windshield Wiper and Washer Upgrade/Conversion – took about two hours with cleaning included and finding tools, yours could take less.

We all know the early wipers and washers suck on the GM square body trucks compared to those available on the GMT400 and newer trucks.

When I was removing things from the donor crew cab, the wipers was a definite must so this is a build thread on how I converted/upgraded to this newer option on my 85 CUCV Blazer. I don't know what year the washer nozzles attached to the wiper arms started but it was interesting to learn the holes for the option were actually already there on the CUCV Blazer body and this was a direct bolt on. If you are lucky enough to get all this from a donor truck at a u-pull-it also get the washer bottle, harness and tubing with the T or Y adapter. The washer bottle has the washer pump physically mounted to the reservoir and is a much better design than the vacuum pump integral to the wiper motor design type.

Here are the (stock) crappy wipers with the washer nozzle poking through the cowl vents.
oldwipers.JPG



This is the wiper arm release clip that will need to be released by a pick.
oldwiperarmclip.JPG




See the clip in the mirror being released by the pick
oldwiperrelease.JPG




You will need to pry the arm base away from the shaft with a large screw driver.
oldarmremoval.JPG




Now loosen the front hood hinge bolts and remove the rear bolts entirely to allow the hood to pivot forward and gain access for the cowl panel to be removed without interference of the rear of the hood. (you can remove the hood entirely if so desired)
lhhinge.JPGlhhoodbolt.JPG




With the hood now tilted forward remove the three cowl mounting bolt (9/32 ¼”socket). There are pins that go into the body at the rear of the cowl to secure it to the body, so lift up on the front of the panel and it will lift out at an angle.

Update to wiring the washer pump into the circuit...

I'm still using the CUCV front and rear lamp wiring harnesses, but installed the Crew Cab donor trucks interior wiring harness to obtain the intermittent wipers, all cluster gauges etc. The two wires for the washer circuit (pink and white) were removed from the donor harness by inserting a terminal removal tool (small screwdriver will also work) into the terminal end of the bulk head harness connector to release the terminals. I then had to remove the brown w/white stripe and black w/yellow stripe (blackout lamp) terminals to replace with the washer pump circuit.

Upon reinstalling the harness I did not have washers yet (quick test of pump checked good) so I removed the wiper delay module mounted to the column and reconnected the harness without the module. Washers worked so I must have a bad module. I also swapped the wiper motors as the factory CUCV wiper motor would not operate in the intermittent mode. Found my spare module and swapped it in...works better but not as fast as I desired. Guess I'm too used to the GMT400 Yukon and GMT800 Suburban’s performance, but the washers are much better for sure.

I'll update the wiring install picture into the bulkhead when I can get to my home hard drive...I'm away on Military Duty until Sep 16th.
Finished removing the exterior lighting & horn override/black out lamp harness from the CUCV interior harness and next plan is to get it modified back into the Civy donor harness from the crewcab.

This is a cool feature on the CUCVs.

With the flip of a switch all the exterior lamps and the horn no longer will work and give your position away in a tactical environment. Flip the switch down and blackout front and rear bumper lamps come on which helps your spacing in a convoy during night driving Ops. Flip the other B/O switch and a hooded headlamp keeps you from being seen from the air but gives you enough downward lighting from a single b/o headlamp that you can still travel.

(Labor Day Wknd 3-5 Sep 11)

Had the interior harness in and out a few times trying to get the B/O wiring installed correctly.

I'm at a stand still until I can review the 87 crew wiring diagrams a little more closely along with the CUCV. I carefully extracted the Packard terminals from the CUCV bulk head and fuse box to reinstall in the Civy's and I have a couple circuits installed incorrectly.

Service lamps all work but I lost brake lights, the left T/S and flashers honks the horn continuously, right T/S activates the buzzer continuously and the horn button does nothing.

I also disassembled the cluster and lined the entire housing and the cluster cover with 3M aluminum tape for reflection purposes for the red back lighting LEDs. I also installed the lighter socket and the fiber optics to the ash tray and installed some corner Kicker dash speakers I got on the http://chevyk5blazer.com for sale section.

I would like to find a good factory Delco ETS AM/FM radio too.



Instrument Cluster Upgrade To Gauges and Quartz Clock and Red LED Back Lighting from 87 Chevy Crew Cab

I've seen some builds on cleanup, painting the cluster housing to brighten the gauge back lighting but took a different approach.

I disassembled the cluster and lined the entire housing and the cluster cover with 3M aluminum tape for reflection purposes.

I then ordered and received some WLED-x5 red LEDs from http://superbrightleds.com to re-bulb the cluster, heater and 4WD Shifter Console back lighting to a more tactical look much like the M-35s and M-923 series Military Vehicles.
cluster3mfoil.JPGclusterdeisel.JPGclusterredled.JPG


(10-28-11)

Took several attempts to get the wiring correct but I finally got it figured out and have the blackout lamp circuit installed into the factory fuse box (no bubba splices) My last attempt had me puzzled for a while...left turn signal constant horn, right turn signal & hazards constant seat belt buzzer no service lights, brake lights, or horn

Installed the harness back in today got it all buttoned up and now no gauges or 4wd light

Had to get away from it for a while so I removed the grille to access the horn. I removed the dual horn wiring from my donor front harness and swapped it with the single horn wire in the CUCV harness. Had an extra horn and works as it should but turns out they are both "F" note horns so I need to go to the pick n pull and get a different note for the factory dual horn option. I also installed some bling from a parting out purchase over on the 67-72 site. It was the chrome and gold bow tie and that isn't quite tactical so hit it with the wire wheel to scuff it up and shot it with a few coats of flat black.





(6-23-12)

Been a while since I made an update but I started working on the CUCV again over the last month. I got another set of dual Horns with the "A" and the "F" notes so I swapped in the "A" note behind the NATO plug and the horns sound 100% better.

I actually had the cluster installed and kept blowing gauge fuses so I thought I might have crossed or shorted a wire and ended up pulling the wire harness again for the umpteenth time;( turns out I had got a little sloppy with the foil tape and was shorting some circuits causing the fuse to blow.

1988 K5 Blazer Seat Upgrade

Installed seats from a donor Blazer I purchased.

I had to swap the seats to the CUCV bases as the Civy bases did not align with the bolt holes in the CUCV floor.


88K5seat.jpg88K5seats.jpg

First things first I siphoned out the old diesel. Man was that stuff smelly! Per SS user
2INSANE he suggested I remove all the old gas, oil, tranny fluid, coolant, and so on. Put fresh gas in, fill the new fuel filter up with tranny fluid and a whole bottle of seafoam. Sure enough, that worked like a champ! M1009 is running great but I am having an issue the m1009 won't turn off when I remove the key so that shut-off solenoid might be bad or it's getting voltage when the key is off???

Joe,

Good to see you started a new post.

Like I told you after I replaced the starter and determined that was the major cause of my starting issue I was having second thoughts on selling.

But I think its found a great home and some new excitement in preserving it more to a daily driver.

I think the factory civilian mods I performed are good ones and hope you do too.

When I get some time I'll research the wiring again for the B/O Lamps, if you look at your post #5 you see I did this labor day weekend in 2011 so memory is a little weak.

Also when the weather gets better I'll look for the gun hardware - its burried in the garage somewhere.

Before you look to replace the seats back to stock CUCV I'd look to have them redone in a simular Mahogany Brown color with todays upholstery materials. These seats are way more comfortable than the factory seats.

Many from other forums that were watching my build over the years would like to see its progress continued so when I see some progress I'll point them here. Hope you finish the A/C install and the Power Windows/Locks.

Got to thinking...dangerous

There should be some coiled up white and orange wires near the kick panels on both sides. These are the civilian dome light switch wires harnesses.

Also the dash portion of the front door power lock harness is running to both sides. Also think there may be some wiring near the glove box area.

The Cruise control wiring is around the steering column thru the firewall and includes a vacuum hose with its harness to go to a brake switch specifically for that purpose.

I absolutely love it! But I would have understood if you had a change of heart, you put in many hours of love and sweat into this gem!

Awesome! I really want to get those up and running, yes haha life is busy so I don't blame ya, I did look behind the water container as suggested but came up empty-handed, I will look further once I have a moment.

Yes, that would be so cool if I could put those back in! Thanks in advance!

That was the plan to get OEM but after sitting in the current setup I think I'll just have them redone and go that route.

Yes please do so I already go some suspension parts coming and I plan on documenting everything!

Thanks again for everything!

I'll have to take some pictures as I plan on putting some LED lights but make it look factory within the cab. Very nice to know that I have those already wired up!

Yes! Can't wait to get the power windows in! I want to get the tailgate power as well, any suggestions on that?


Is there anything more I need to do so I can get that running? Is it a simple plug-and-play for all said wires and vacuum hose?


Thanks again, Art!
